Gotenks
In a nutshell
Gohan is a very defensive character capable of effectively countering every method of attack his opponents try. He is a charge character, and as such, is perhaps the only character who is at his best when down-backing. He has the best anti-air in the game in the form of a flash kick, strong crouching normals and multiple good guard counter options. The trade off is that he is generally bad when he is forced into action, having no mixup game and no good options against heavy zoning. For Gohan, defense is the best offense; space yourself at midrange so that you can react to your opponents' pathetic attempts to mount an offense, and if they start turtling and regenerating, feel free to start hopping all over them, or just regenerate yourself.
