Mar's tail lashed out again as Kodai charged, whiffing through the water as he stopped just shy of being hit and dived instead. That was good, he could take a hit but wasn't a meathead about it and knew how to adjust his strategies. She was about to race off again when suddenly Kodai transformed again and she found a massive whale-like dinosaur looming in front of her. Immediately a tingle of unease went down her back and along her tail, the sheer size putting her on edge as she hesitated for a moment. The huge blip of an electrical field was putting her on edge too, but that was something most other people wouldn't understand.

She really, really wasn't a fan of huge creatures and especially not huge whale-like creatures in the water, and reflexively muttered a warbled "Big..." to herself.

But she had a student to teach and needed to set a good example so she pushed those irrational feelings aside and made her move. Not for the ocean floor, but up towards the surface - aiming to launch herself out of the water with enough speed and power to arc through the air and hopefully make Kodai lose sight of her as she used his current forms size to try and get into his blind spots. She'd have to be careful to not get hit, but if she managed to dive back into the water she was going to do her best to stay out of his line of sight. The benefit of being so small compared to such a large opponent was every movement Kodai made would be easy to see - and feel, with the shifting of the water - coming.

Plummeting towards the ground with Serpent, Mar's tail slapped against the side of a wall they were fortunate enough to fall near and redirected their momentum sideways. It was still a rough landing, but far safer than falling straight down into concrete. Not for her own sake - she used Serpent as a cushion anyways - but to make sure the villain didn't get too hurt. Between some blood loss and the impact though, he was definitely down for the count. Opening her mouth to make sure she didn't make the bite worse, the shark hero had a sleepy look on her face as she went through the motions of using a piece of Serpents own clothing as a makeshift bandage.

Even though he was unconscious for now, Mar kept one hand on the side of his head so he couldn't try to aim at anyone and get them with a sneaky blast as she went about restraining him properly.

"Good work, Phanta-aaahhh-smagoria." Mar returned the thumbs up only to bring her hand to her mouth to stifle a yawn mid-sentence. She was exhausted after using so much energy and could really use a nap around now. In response to Lucille's question she held her thumb out sideways in a so-so gesture that meant she was fine but tired before asking: "Arm okay?"

Finding a cozy enough wall to prop herself against while Hotshot finished up with Stoneskin, the villain ended up crashing through the building barely a foot away from her. It didn't bother her any, arms crossed under her chest and head down as she did her best to resist the call of a nap for a little longer. She was listening though and she chimed in with a deadpan "That's right." to go along with Lucille's teasing. Besides, a bloody steak dinner sounded good right now. With a nod and retrieving her cellphone, with a blue and white shark case on it, and finding a wall to lean up against she called it in. "Tiburón here. Need pickup, three villains. Minor injuries."

Hanging up after the extremely concise call in, Mar gave her side a rub before chiming in once more on the banter between Lucille and Hotshot. "It's good exercise anyways, Lu-Lu..." Head tipping down, Mar fell asleep on the spot.

Back when she had first become a pro hero, the brief glimpse she got of lightning clipping Lucille's wing or Hotshot's clear exhaustion would have distracted her and she definitely would have gotten herself squished. Today though? Mar knew to have faith in her fellow heroes and knowing when and where she needed to intervene, and sludge raining down from above was all the signal she needed.

"It's called Hollow Hunger, I'll let you judge if that's cool or not." She answered, dipping backwards as the hammer hands barely missed crushing her. The two big blocky quirk-enhanced hands slammed together with a thunderous bang, Mar's foot coming up as she turned to the side and slammed her foot down on the top of his hands hard enough to make him stumble forward. Then she was hopping over him before he could recover, tail smacking him in the face as she went and making him stumble backwards with an angry growl as he whirled around to try and swipe at her before she could follow up with an attack at his back. Except, Mar wasn't there and his fist hit nothing but air as the shark hero bolted away from the fight.

"Running away? Some hero!"

Instead of replying Mar shouted: "Shift Change!" and jumped onto the nearest sludge puddle as hard as she could. Instead of splashing or getting her feet stuck it it she was launched into the air like she had jumped on a trampoline. Mere moments after Serpent declared his victory Mar's sharp teeth dug into his right shoulder seemingly out of nowhere, the Shark Hero clamping down at just the right spot to make it hard to use that arm without getting too close to his neck. At the same time one hand came up to slam against the bottom of his jaw pre-emptively, forcing his mouth shut as he reflexively yelled in pain and snapped his head down to try and blast her off him. The pair zigged and zagged in the air, Serpent doing his best to try to shake her loose without getting himself hurt further and struggling to get a clean hit on her with his claws.

As long as she kept Serpent from getting her with a solid claw swipe or a blast of electricity, all she had to do was wait it out. A little blood loss wouldn't kill him, but it would ensure he couldn't fight much longer at his full strength. The landing might be a little rough, though, if they did fall... but she'd cross that bridge when she came to it.

Mar pursed her lips thoughtfully at Kodai saying he hoped he wouldn't be a disappointment. If she was Lucille she'd probably give him a warm smile, maybe an encouraging pat on the back or something, and some kind words? Mar wasn't sure if she could pull that kind of reassurance off, so instead she just made a mental note to keep an eye on Kodai's self-esteem for now. It wasn't uncommon, especially among first years, and he'd probably grow out of it just fine. If not, well, that was what the teachers and the school councilor was for, right? She wasn't sure what he was so deep in thought for either but she tried her best to be patient, even if she hated waiting, and she could sense little blips of extra electrical activity from Kodai so she assumed he was doing... something. If it was Quirk related or Gear related she had no idea, but it was a little bit more electrically active than it had been a bit ago.

Finally he was ready and transformed into what looked to her like a really long nosed dolphin-shark-tortoise-thing, sort of. She couldn't be certain since she couldn't see colors at all, but the shades of gray of his transformation blended in with the water enough that she was already considering that this could be great for infiltration in the future... if she could get someone to confirm that the form blended into the water as well as she thought it did.

But then they were off, Kodai lunging after her through the water with just as much speed as she had launched herself, and right away Mar had to twist in the water and with another flick of her tail send herself off at a diagonal angle to evade his first attempt at grabbing her. She wasn't sure, but that extra long mouth his transformation had would probably be able to snag her pretty easily if she wasn't careful to keep track of her legs, arms and tail while evading. So another flick of her tail sent her down towards one of the deep, narrow crevices in the simulated ocean. Some spots were even too small for her at their narrowest point, so navigating it without losing sight of her should prove a good exercise.

If he did happen to lose her though, she was going to pop out where he could see her again just to keep the training going - she wasn't here to win, she was here to train a student who needed to get used to the water.

Kodai clearly thought his answer wasn't very good or helpful, and maybe the perpetual sleepy expression on Mar's face didn't help, but it actually gave her an idea of exactly what she needed to do. "Alright, we can do that. First things first then, show me what you can do in the water as is and that'll tell me exactly what level of training you're looking for."

Hopping into the water herself so that she could easily observe any underwater activity without the reflection on the water surface or any other kind of distortion getting in her way, she floated about with just enough movement to keep water going through her gills. While it looked calm and flat from the surface, underneath it was a whole simulated ocean complete with uneven crevices that went down deeper, artificial rocks and coral, and plenty of sandy slopes and hills. Letting Kodai have some time to go through whatever he felt like doing to showcase where he was at to her, Mar was going to get down to the actual training. Popping her head back above the surface to speak clearly, she got ready to use up a whole bunch of energy. "Kodai-san, I'm sure you already know from your combat teachers that movement and positioning is one of the most important parts of a fight, right?" She paused long enough for a response before continuing. "And sometimes a fight is also a chase, on and off, and its a hero's job to try and apprehend the villain without letting anyone get hurt in the process if they can help it. But in water you have to worry about up and down a lot more, and cornering someone isn't as simple as it is on land. So we're going to have a race and I want you to do everything you can to try and capture me. Sound good?"

If he didn't have any objections, Mar was going to give a "Ready, Set, Go!" before diving back underwater and with a powerful flick from her tail send herself rocketing through the water. She wasn't actually all that much faster than him, she assumed, since she wasn't a speed focused hero or anything. But she had experience in moving around underwater, and she wanted this to be a learning experience - so if Kodai tried to grab her she was planning on making hard work.

He might surprise her and get her on the first or second try, but she had some tricks up her sleeve and was planning on making him learn to restrict her movement options if he didn't figure it out on his own right away.

Mar was maybe a little late to the party. Not because she had been busy with work of the heroic or teacher-ic variety, but because her quick power nap had maybe gone on longer than expected. She'd been using a lot of energy lately though, so could you blame her? She doubted anyone would hold it against her, but she hurriedly donned her costume and made her way to join the rest of the teaching staff and visiting heroes unwinding and having fun.

So Mar joined the party wearing a cowboy costume she had modified to account for her tail, a prop lasso wrapped around one arm. Bringing one hand up she greeting everyone with a still-sleepy-sounding: "Howdy, ya'll." in her best attempt at a cowboy impression. Which was comical more than accurate, especially with the half-dead lack of energy she put into it right now. But she didn't pay that any mind, turning her attention to seeing who else was here and what costumes they had come in. She spotted a big frog, a hula girl, a really elaborate princess looking kind of outfit, a mummy, some kind of horror villain, a couple she didn't recognize, two that seemed to be wearing normal clothes but maybe it was some kind of cosplay? And when she spotted Lonewolf, Mar almost wanted to facepalm - she'd gone with cowboy because she figured nobody else would here in Japan! Well, at least his outfit was different enough from hers, going for a more realistic approach or something, that she didn't feel too dumb.

She was still waking up a bit, but she had heard something about a costume contest on the way in? Honestly she wasn't sure who she would vote for, everyone had fun costumes - even if she didn't get what some of them were. Maybe the frog, since it seemed the most unique... She'd give it some thought while seeing who to chat with, maybe check out the drinks and snacks while she was at it?

"Fine!" Mar shouted back to let Hotshot know she was good. A bit sore, and definitely getting tired, but no concerning injuries. Cracking a sharp-toothed smile of her own in response to Lucille's, she brought her arms up over her head in a quick stretch as the three heroes successfully regrouped. "Don't worry about it if I pass out the second we're done here." She noted quietly, more for Hotshot's sake than Lucille's. Lucille was already well aware of how quickly the shark hero could slip into a nap after a fight.

"Yeah, I got him. Some kind of blocky, armored-arms thing or something." She wasn't sure how to describe it really, so she called out a quick: "Oi! Big guy! What do you call your Quirk-hands-things?"

The big guy looked surprised and like he was about to reply when suddenly his two allies were on the move and he wasted no time in following suit. While Hotshot handled the small one and Phantasmagoria handled the fast one, Mar had to duck and weave to avoid the barrage of palm strikes being sent her way. He was advancing on her too, forcing her into a slow retreat. Probably trying to break them up again. The attacks was one thing, but his tough talk prompted her to scoff as she dodged and twisted, tail slapping out to catch against the side of his extended arm and forcing him to stumble to the side. "Yeah, I'm tired, so the sooner we deal with you guys the sooner I can sleep."

Mar followed up with a kick, the man blocking with his palms as he tried to regain his footing and momentum. Mar didn't press the attack though, slipping around to the side as he lashed out with another palm strike that would have caught her in the side if she hadn't been ready to dodge. As it was it still glanced against her like she'd gone sliding shirtless across a brick wall, leaving a stinging abrasion where his hand had passed by.

"Then let me send you into an early nap with these hands of mine - I call them Hammerhands!" Another tail slap pushed the big guy back a little as he continued his pursuit of Mar, and the hero paused long enough to ignore the stinging in her side and ask: "Like the shark?"

"No!"

Apparently he didn't like that comparison because his charges came faster and more reckless. The problem was, her attacks didn't seem to be bothering him all that much either. Phantasmagoria and Hotshot seemed to be in standstills of their own too, but Mar wasn't too worried. She just needed to wait and find the right moment to give a decisive strike.
