By the time Gogeta arrived back at Earth, Whis was already there. "What form is this?", Gogeta asked. "Super Saiyan 4. You most likely are unaware of this, but when Frigid was controlling Fris, he merged another universe with our's. That universe contained this form.", Whis explained. "We should go to Kami's Lookout and come up with a new plan.", Gogeta said. "I have a better idea, we should have a base in the Time Chamber.", Whis recommended.
Gogeta was then unfused. "Sorry to say this Whis, but I've already entered the Chamber twice, I can't go in again.", Goku explained. "I can remove that limit.", Whis informed the two.
