Well, I don't really understand the question but I'll try this answer.
Vegito has no time limit because of the potara earings which make two people one.
Gogeta ( Super Gogeta) has a descent time limit depending on strength of the two people.
Gogeta (Super Saiyan 4) probably your capitalized Gogeta, has a short time limit because of how strong Super Saiyan 4 is. Now if this doesn't help I do apologize but this is how i read the question.
Goku and Vegeta dont Transform in the story of the original anime only in the DBZ movie Fusion Reborn which i believe is movie #12.
when you beat the game (after you beat kid buu) you can do almost all levels over (in alternate version) and you do those over and you will get the characters you dont have. this only includes (broly,super buu,and gogeta)
first it start by looking like a rash and it starts to scratch and itch a lot it begins to cold down when you dont scratch then the more you scratch the faster it looks like a lump on your face it constantly grow until it limite it really cotagious keep that person away from people and dogs and other animal
you do a partner fight e.g vegeta and goku. please note that you must unlock the fusion you want from story mode, you press 2 on wii im not sure on others. You must have suffiecient blast stocks
