After the death of Wingfoot's grandfather, the Keewazi chief, the Council of Elders called on Wyatt to accept the position as tribal chieftain. At the same time, the alien known as Terminus came to Oklahoma to devour Earth's resources, and the Fantastic Four arrived for battle. Wyatt met the foursome's new member She-Hulk, and he helped the team battle Terminus. Wingfoot postponed his investiture as chief of the Keewazi, and followed the Fantastic Four instead, returning to New York with Mister Fantastic and She-Hulk. Alongside the Fantastic Four, he journeyed to an alternate Earth, and helped battle the Warlord. He soon began an intimate relationship with She-Hulk, and helped her confront magazine publisher T.J. Vance. He continued this relationship after she left the team (after the Thing's return) and ended up becoming involved in her adventures as well. He was part of a group of innocent citizens kidnapped by a teleportation beam when S.H.I.E.L.D. went after She-Hulk. He helped her to escape confinement by pressing the appropriate amount of weight onto the pressure-sensitive floor of the cell they were confined in. This was a difficult task as She-Hulk is much larger than his already tall form. This incident was part of an internal power struggle within S.H.I.E.L.D. and to further complicate things, one of the citizens was actually a sentient colony of cockroaches. They went after the corrupt S.H.I.E.L.D. officer in charge, endangering everyone on board and anyone the helicarrier might crash in to. She-Hulk soon neutralized the threat, and Wyatt survived the crash of the helicarrier. Alongside the Fantastic Four, Wyatt then battled Doctor Doom (actually Kristoff). Alongside the Fantastic Four, Wyatt later investigated a temporal zone surrounding Central City, California. Wyatt then attended the wedding of Johnny Storm and Alicia Masters (actually Lyja in disguise). Wyatt later became engaged to She-Hulk; alongside her, he battled Carlton Beatrice, and then broke off the engagement. Wyatt later accompanied Ka-Zar and Shanna the She-Devil back to the Savage Land.
