After Wii Fit Trainer's training, the gang was set to continue their adventure and ended up at Suzaku Castle, But first, here comes a new challenger. There was a thunderstorm, and the challenger was in his fighting-ready stance. He said, "I'm looking..." then, Link, Samus, Fox, and Spider-Man faced the challenger in the shadows. He then said, "For a..." and Link, Samus, Fox, and Spider-Man stood there in their fighter-ready stances. Finally, he said, "Challenge." He then came out the shadows and said, "Hadouken!!", while doing that attack ar the four of them.

It was the Wandering Martial Artist, Ryu.

Ryu: "Well, this is Smash...come on."

Mario came in with a Neutral Aerial, but was discarded by Ryu's Up Tilt and Shoryuken.

Ryu: "Shoryuken!"

Did his Standard Attack on Link before finishing him off with a Dash Attack.

Ryu: "Kyah!"

Pit held up his shield, but was shield-broken by Ryu's Side Tilt, Collarbone Breaker.

Ryu: "Hyah!"

Duck Hunt tried to get him with Wild Gunmen, but Ryu ducked and was repeatedly using his Down Tilt Attack (Weak) until the Gunmen was pantsed and was embarrassed while Duck Hunt laughed, but Ryu was serious. He did his Up Throw on Falco and threw him upward, but Fox came in just in time and got Ryu's heel from the aftermath of Ryu's Up Throw and Down Smashed him.

Ryu: "Ha!"

He fired an Hadouken, his Standard Special Move.

Ryu: "Hadouken!"

He did his Side Special, Tatsumaki Senpukyaku on Rosalina and Goku.

He did his Up Special, Shoryuken, on Mega Man.

Ryu: "Shoryuken!"

Ike then came while Ryu was charging up his Down Special, Focus Attack, but reversed it when he saw Ike row around him and got him, and Ike was stunned.

Ryu: "... Koo-yah!"

Captain Falcon used a Turnaround Falcon Punch, But Ryu's Focus Attack acted like a counterattack and took the blow, while Captain Falcon was stunned and Ryu cancelled his Focus Attack state and used his customized Shoryuken.

Ryu: "Shor-yu-ken!"

He did his Back Throw on Blaze and broke one of the signs. He went up against Lucario by using his Front Air, Up Air, a couple of (Weak) Down Tilt attacks, then a (Strong) Down Tilt, He then used customized Hadouken, but red, called a Shakunetsu Hadouken.

Ryu: "Shakunetsu."

He then finally finished him off with a Down Air Meteor Smash.

Finally, there was a Smash Ball and Ryu got and did one of his Final Smash, Shinku Hadouken.

Ryu: "Shinku... Hadouken!"

After that, the others wanted to recruit Ryu to join their team since heroes always worked together.

Mario: "Cool, we got another third-party character, who is also from Capcom like Mega Man."

Goku: "Ryu. It's good to see you again, since we battled in the Tournament."

Ryu: "Son Goku. It's good to see you again too. I heard this world is in danger. So I'm here to help."

They all started to go to the Final Destination where Master Hand, Crazy Hand, and the other villains were.
