Knuckles the Echidna

Knuckles is a character originating from the Sonic the Hedgehog franchise. He has a minor role in Phoenix Wright SPEED Attorney and a supporting role in Phoenix Wright Turnabout Portal.

As a Police Officer
Knuckles first appears in Phoenix Wright SPEED Attorney as a police officer watching over the scene of Big the Cat‘s murder. He tells Phoenix Wright that he can’t investigate, but he changes his mind after Phoenix informs him that he is an attorney. He asks Phoenix not to touch the scene, but Phoenix searches anyway and finds a Chaos Emerald, which proves instrumental in solving the case and revealing that the murderer was Shadow the Hedgehog, rather than the defendant, Miles ‘Tails’ Prower.

Phoenix’s Ally
While pursuing Manfred von Karma, who is on the run after being accused of sending a ‘cake bomb’ to Phoenix’s Office, Phoenix and Dick Gumshoe find themselves in Sonic World, where they meet Sonic. After explaining the situation to him, Sonic decides to gather his friends to help apprehend the prosecutor. Manfred and Doctor Eggman then confront Phoenix and Gumshoe before escaping in Eggman’s ‘egg fly car thing’. Sonic returns with his friends, and Knuckles is among them. Tails and Shadow are present as well. After Phoenix informs them that Manfred and Eggman intend on taking over Ace Attorney World, he finds a note on the ground revealing that they intend to steal Chaos Emeralds and then go to Mario World for power-ups. The group decide to go to Mario World to catch them. Knuckles reveals a Chaos Emerald and throws it on the ground, creating a portal.

After arriving, Shadow suggests that they wait for Manfred and Eggman to arrive. Two hours later, Mario appears and informs the group that they were present two hours ago, and that they have now gone to Bowser’s Castle.

Upon arriving, the group discover that a moat separates them from the castle. Knuckles attempts to jump over the moat, but falls in and dies. Tails tells the group that he’ll respawn and they go on without him. They are caught by Manfred and Bowser and locked in the dungeon, but Mario manages to blow up the door so the group can escape. Unfortunately, he also accidentally destroys a pillar, and the castle starts to fall down. Knuckles, who has respawned, gets killed again when a rock crushes him.

Knuckles respawns again during the final battle with the BESK team’s giant robot. He attempts to punch it, but it crushes him and kills him once more. It is unknown whether he respawned again afterwards.
