Not to jump on the bandwagon, but I agree with the sentiments so far. I have no hatred for Broli, I found the first movie to be entertaining (the second and third were rehashes, but had their moments). Still, it is a bit goofy to go, "Well, he's invincible. Just because."
Besides, with all the entertaining alternate universe tales, it seems like a lost opportunity. I mean, I'd gladly take a reality where something unique happened, like Broli was the Saiyajin sent to Earth, who was adopted by Son Gohan and raised to be Earth's savior (but just happened to be the legendary SSJ). I mean, come on. How cool would it be to see Broli in the trademark orange gi proclaiming that
he was Son Goku?
Not to mention,
that would be an interesting flashback comic. Instead of Movie 8 in a very-slightly altered form, we'd see DragonBall if a good-hearted Broli was the protagonist. Not to mention the other ramifications it would have (Broli fathering Gohan anyone? Vegeta absolutely crapping himself?
).
