Raiden

Raiden is a cyborg ninja from the Metal Gear series, specifically introduced in Metal Gear Solid 2. While he is a minor cameo in the original YTP series, he is a major player in the game.

Characterization
In the original YTPs, Raiden did nothing but cut one tree a whole lot. However, in the game, he does not do this. Instead, he is found in a cloud by Raichu, who saves him. Raiden's function is mainly in battle. He has defeated or assisted in defeating the following: Several bears, several cacti, the Troll Cloud, the Sun Baby, several WarYEEors, and a Super TaYEEnk. The obvious reason why he doesn't do much outside of fighting is that he's a bit of a psycho. The less obvious fact about him is that he's too scared to jump down from a cloud.

Abilities
As a cyborg ninja, Raiden has superhuman strength, speed, and durability. He also has a high-frequency blade, which can cut through nearly anything, including objects that can not physically be cut, such as fire.
