Charles would sigh as he watched the other students, shaking his head as he stood up "I guess it be my turn then.." he says softly to himself thinking to himself about the powers that was shown. Even though he already showed the teacher an idea of what he was capable of he decided to show some more for the others "I'm a slime man.. I can take any appearance I desire for a time as long as I have enough mass.. along with other things I can do" he simply states to them as he turns himself into werewolf and back, then simply brings up his hand and it extends rapidly turning into a spike, he'd stop it before it went to far returning to his normal slime form before returning to his human form again. "no need to be aggressive to show off mine after all unless it's just to show off how I can take a hit" he simply states before sitting back down next to Koharu waiting to watch the next person.
