Go Go Tomago, as portrayed in the "Big Hero 6" manga series titled "Baymax" in Japan, is an adaptation of the film protagonist of the same name.
Go Go Tomago is a sarcastic, laconic and blunt young woman who is a directly involved participant in the special science program at the San Fransokyo Institute of Technology.
Go Go has a pretty strict no-nonsense policy and holds a very calm, cool, in-control, unaffected, tough-skinned and untouchable persona that only ever comes undone in her relationship with Hiro, often to comical effect. This interaction between Go Go and Hiro is often sparked by them intentionally getting under each other's skin, resulting in the other lashing out in passionate frustration (accompanied by violence on Go Go's part). As shown in her interactions with Hiro, Go Go seems to have no qualms about laying her hands on other people if she sees fit, Hiro being her favorite target (much to his chagrin).
Go Go was involved with the science program at SFIT along with her friends Honey Lemon, Wasabi, Tadashi and Fred. It was here that she met Hiro Hamada, Tadashi's genius brother. Not long after meeting him, she told him to "Woman Up" before promptly striking him on the head, giving him a look and leaving the room. Following Tadashi's death, she agreed to help Hiro along with the other members of their circle in his quest to catch Tadashi's killer. She immediately attacked Hiro thereafter when he blatantly called her dumb in a sentimental speech of gratitude.
- In the manga, Go Go and Hiro have what is described as a "love-hate" relationship, where the individuals actively express feelings indicative of animosity and general frustration towards each other despite the underlying care that they share for one another.
- In Japanese literature, this relationship is often classified as and paired with the term, "tsundere," a combination of two words reflecting an active flop between that of an antagonistic and brusque disposition and that of a caring and warm disposition towards a character.
