Suggested by Sonic Ryu got a good boost thanks to Asura’s Wrath but I don’t think that will be enough to take down Frieza here. Frieza got his golden form which massively boosted his stats to the point where there are very few who can reasonably hope to take him down. Ryu has the edge in actual combat skill but it just doesn’t make a difference when your opponent is that much stronger than you. They aren’t in the same league and Frieza could end the universe on a whim. Frieza wins.
