History[]
Tracking Knuckles the Echidna[]

Willoughby and Mason track Knuckles
- "Agent Willoughby, we got a problem. It's a code red, Knuckles has left the Green Hills Zone. We have to inform Commander Walters."
- ―Fairley to Willoughby[src]
In 2024, when agents Willoughby and Mason were tracking Knuckles the Echidna, who was leaving Green Hills, Montana, agent Fairley suggested they report this to Commander Walters. Willoughby proclaimed control of the situation, taking the SAT surveillance offline only for her to access. Mason disposed of Fairley by banishing him to the Mushroom Planet. Willoughby called The Buyer afterward, promising to bring him Knuckles within 24 hours.[1]
Infiltration into G.U.N. Headquarters[]

- "G.U.N. Headquarters is right there. Let me go in, get the key and destroy anyone in my way. I want revenge!"
"Patience, Shadow. Just let us handle this, and I promise you'll have revenge on a scale you couldn't possibly imagine." - ―Shadow the Hedgehog and Gerald Robotnik[src]
Team Sonic and Team Robotnik, the latter being led by a vengeful Gerald and his estranged grandson Doctor Eggman, both infiltrated G.U.N. Headquarters for the second keycard to the Eclipse Cannon. In order to hit G.U.N. HQ with the cannon before the destroying the entire world with it, the Robotniks danced down a laser hallway while Tails took control over the building thanks to Tom and Maddie Wachowski, disguised as agents Randall Handel and Rachel. Sonic chased after the Robotniks, bypassing the building's forcefield and finding himself in the vault where the keycard was held. Rockwell stopped them from taking it by operating tiles with variable gravities, the system controlling it being broken by Knuckles.

Once the floor's effects wore off, Rockwell took the keycard, Tom, disguised as Walters, taking it from her. As Tom attempted to leave, Shadow teleported inside the building, punching Tom and taking the keycard for himself, teleporting back to the Space Colony ARK, which started to ascend to space, and giving the key to Gerald while Tom is hospitalized outside the headquarters.[2]
