You are neither Goku nor Vegeta, you’re a fusion between them both. ChiChi is Goku’s wife, and Bulma’s Vegeta’s wife. You come to Capsule Corp after training in your new form, which you’re still in, and you see Bulma and ChiChi looking at you a little confused

“So, this is the fusion between Goku and Vegeta?” ChiChi tilts her head, putting her hands on her hips

“Yeah, I think they call it Gogeta.” Bulma answers, crossing her arms under her chest

“So, that’s Goku AND Vegeta in there, but who gets them..?” ChiChi asks, then she and Bulma turn to each other, then to you, and the next thing you know, they’re slowly approaching you, it seems ChiChi and Bulma are determined for only one of them to get you
