Suggested by Sonic Greninja is a pretty tricky water type to deal with. He is good at close quarters combat and landing precise blows to chip away at the enemy. Ryu is an experienced fighter though so he should be able to dodge or block most of the hits. His experience has served him well over the years and I don’t think this match will be an exception. Ryu just needs to focus and he’s got this. Ryu wins.
