I have found him rather annoying opponent, since - believe me or not - his wings always prevent me from seeing what's he doing. And because his wings are always on the move, they distract me quite succesfully. And more than that, sometimes the wings even hide my own character from me. "Oi! Where did you go? Ah, there you are... lying on the ground..."
One of the three outpowered girls, at least in TTT. I just finished playing few arcades through in TTT with Yoshi- and Kunimitsu, and Jun was always a "problem". Her hits make a lot of damage and she has a large variety of 'em. I guess the same goes for Unknown, too, since she always imitates Jun first.
Nothing especially, only that his blows keep me in the air for quite a time. His kick spins the character at least 360?, even more, maybe. His punches stun easily. Luckily tho', he's not as fast as Xiaoyu.
Nothing fancy. Just plain bored at his face.
"I won't play as him/her!"-characters:
I'll play, once someone tells me how to make him stand on his own two feet for once.
Just plain annoying. I just don't like her. That's it.
They're clumsy. They're slow. I don't fight with the animal characters.
Just take a wild guess why.
That's my list. How about yours?
