Ryu (Super Smash Flash 2)

Ryu is a veteran unlockable character in Super Smash Flash 2. He was revealed during the Day 2 livestream at Super Smash Con 2019. His moveset and voiceclips are taken from and Street Fighter IV. His sprite design is based on his appearances in Super Smash Bros. for Nintendo 3DS and Wii U and Super Smash Bros Ultimate.

Attributes
Ryu's ground mobility is around average. Oddly, his air acceleration is one of the highest in the game, in direct contrast to his extremely low acceleration in the official games.

Ryu has very good frame data, with most of his neutral and special moves falling under that category. Most of his moves have some use in his core kit. His down special can paralyze opponents and is especially good when punishing unsafe moves or baiting commits. His neutral special can gimp opponents with bad horizontal recoveries, due to its horizontal-only hitbox.

Ryu's throws are fairly decent. His back throw can create tech chase scenarios at low percents, turning into a kill throw at later percents. His forward throw can lead into aerial combos, due to having low base knockback and low knockback growth. Lastly, his up throw can start combos against fast-fallers.

Ryu does have some weaknesses, as he has a very poor vertical recovery. His horizontal recovery methods are also easily exploitable and laggy, thus, Ryu can struggle a lot against characters with great edgeguarding games or zoners. Plus, he has little to no approach options, considering all his Hadoken variations can be easily cancelled by any attack.

Trivia
