I thought I would make a blog where users could make their own what ifs. As long as their appropiate, I'll add then up here for other users to see. I have three ideas:
"Surpassing Fathers": Gotenks tries to prove he's stronger than his dads. He battles Goku and Vegeta at Super Saiyan 3, and wins. Gogeta appears and challenges him. He manages to defeat him. Vegito then appears in front of him. Gotenks barely beats him.
"Reunited Brothers": After his defeat on Planet Namek, Mecha-Frieza returns to Earth, bringing Tarble with him. When they arrive, they find Vegeta. Vegeta is able to convince his brother to help him and he switches sides and helps Vegeta defeat Frieza.
"Gogeta Unbound": In order to prove he's the strongest in the universe, Gogeta releases 10 random villians from Hell. He accidentaly releases Dr. Wheelo, Lord Slug, Turles, Janemba, Bojack, Android 13, Broly, Cooler, a Meta-Cooler, and Hideugarn. After defeating them all, Vegito appears. Gogeta manages to defeat him, proving himself the strongest.
Bardock.'s What Ifs:
The deep evil released: Not vegeta, but piccolo becomes majin, he and gohan pull up a big fight, but since their friendship is so strong, piccolo recognises gohan in the end and together they're going to try stopping majin buu (majin piccolo = the ultimate what if character :P)
An unexpected fusion: Piccolo and Vegeta are facing super buu, first goku and gohan wanted to fuse but buu killed them both before they got the change, the only way left to defeat buu is for those 2 to fuse and creating vegeccolo/picceta!
A metal match: In hell mecha frieza and metal cooler have a match to decide who is the true strongest of their kind!
A different world: Bardock is so angry on frieza that he becomes super saiyan right before him, frieza transforms into his second form and the battle for the planet vegeta begins right in front of it!
Ire flowa222's What Ifs:
tarble:the super saiyan!? on namek tarble has to fight the z-fighters and easily outclasses them...but when he has to fight vegeta things take a turn vegeta fights frieza and get's killed tarble is enraged at his brother's death and turns into a super saiyan and kills frieza with his ultimate galick gun and leaves namek in a space pod
