Okay, so Tea's been scrubbed out, and replaced with a tiger.
Name: Yeong Lee
Nickname: Leon
Code Name: Tiger
Age: 21
Gender: Male
Appearance:
He never wears a top because he's always warm due to his fur (although shedding in summer is a bitch), and although he'd rather not wear pants, he understands the need for them... in fact the Professor kinda made it a rule after an embarrassing incident when he ran past the girls dorm sans clothes. Luckily, the Prof. was able to wipe the incident from everyone's minds, except Leon's as punishment.
Powers: Leon possesses the ability to perform what he calls "The Sonic Roar". Basically an hyper enhanced version of the fear-inducing attribute big cats' roars have anyways, Leon's is strong enough to destroy a solid wall. Luckily, he has a decent enough level of control over it to not wreck everything when he speaks. But beyond that, he can't control it's strength. He only uses it if he's damn sure it's necessary. Other than that... well, Leon is a tiger... everything else is related to that. He's agile, flexible, stealthy, has enhanced senses, claws, fangs, about 2x the strength of a normal human, and a highly dextrous tail. He does have cat weaknesses too. He LOVES to be petted, shiny objects distract him easily, he likes to chase things (and hunt things), and yes... he will fall for the laser pointer trick... Every. Single. Time.
Personality: Leon is a guy who loves to have fun. He's always running around, looking to for something to do with anyone. He's really easy to be friends with. He's also noble to a fault. Unfortunately, he's also highly competitive and hates to lose. Plus he can be very, very territorial. Most of the time he can keep it within reason, but really... don't take his things or argue with him when he says something is his. On top of that, he loves to flirt with and tease the ladies of the mansion, no matter if they are single, taken, shy, outgoing, pink, blue, green, fluffy, fat, skinny, he doesn't care. "A kitty's a kitty" (I'm sure you can figure out what the pun is. And it's actually ironic. He has no idea that a certain word can be used to describe a cat AND lady parts. He's actually talking about himself being friendly).
History: Lee was born to a Chinese mother and American father in a small town in Ohio. His only physical mutation at birth was his tail, but his parents loved him anyways. Because he was bullied growing up, his mother taught him how to defend himself, but only if necessary. As he grew, though, he began to develop more tiger-like traits. By the time he was 12, Leon was an adorable little tiger-boy. But this only made it harder to hide being a mutant and the stress made it hard to contain his more cat-like nature. One day, he ending up biting a kid who picked on him, sending the kid to the hospital. Leon was so ashamed he ran away. Unfortunately, that night, the boy's father found him and started wailing on him. Scared for his life, Leon remembered something he saw in a documentary on Tigers and roared at the man, trying to scare him away. He ended up both deafening the man, and shattered his glasses, blinding him in one eye. The scream led his parents right to him, and horrified, they knew Leon couldn't stay. So they sent him away to live with relatives up in New York. While there, Leon refused to speak, scared he might kill someone, and spent the next eights years as a mute. Desperate to help him, his aunt and uncle finally managed to convince his parents to talk to a man well known for helping mutants. Next thing he knew, Leon was standing at the gates of the X-Mansion. Here he felt accepted and free. He even began to speak again, learning how to control his "Sonic Roar", and getting back to how he used to be. Fun.
