Go Go Tomago is a character who appears in Kingdom Hearts III.
When San Fransokyo comes under fire by the Heartless, Go Go and the rest of Big Hero 6 run into Sora, Donald Duck, and Goofy during the battle on the San Fransokyo Bridge, and the parties decide to team up to turn back the invasion of the Heartless. Go Go is first seen being sent flying, nearly hitting Sora, Donald, and Goofy, before Hiro and Baymax arrive to see if she's okay. After Baymax runs a medical check on her and finds that she only suffered a concussion, Go Go is still out of action for the time being while Baymax aids Sora, Donald, and Goofy with dealing with the Heartless on the bridge and forcing them into retreat, as Baymax diagnosed that Go Go was not to be moved until her head could be stabilized.
Back at Hiro's place, a recovered Go Go and the rest of Big Hero 6 are disgusted and disheartened by the headline in an online news article regarding what happened on the bridge, which casts doubt that the team can defend San Fransokyo and encourages the citizens to evacuate while they still have the chance. After Hiro formally introduces Big Hero 6 to Sora, Donald, and Goofy, Sora explains about the Heartless and their origins to the team. When Honey realizes they have no way to actually combat them, Go Go voices her concern that they are just giving up, with Baymax calculating their odds to be very slim to none. Hiro decides to put Sora through a simulation to help the team combat against the Heartless. This inspires Go Go to have her discs defy gravity to climb up buildings to evade and attack from various angles, giving her a wider attack range. After getting a good name for their team, they are soon called to action again when the Heartless launch another attack on the city, where they soon have to contend with the original Baymax that Hiro had to leave behind when he rescued Abigail Callaghan from Alistair Krei's Silent Sparrow portal when they fought her father as Yokai, who has now been corrupted by the Heartless and is attacking the city alongside the Heartless. With the support of Sora, Donald, and Goofy Go Go and the rest of Big Hero 6 are able to defeat the corrupted Baymax and restore him to normal.
During the game's credits, Go Go and the rest of the team continue to defend San Fransokyo with both of the Baymax by their side and strike a pose to the cheering crowd.
