But i've only seen this happen a few times in the series. so i will have to give it a thumbs down. Because i think it will be a waste of time. But thats what i only think, maybe someone other people will like it.
In the Series when Gokou and Vegeta are getting knocked around
by Super Buu and Gokou is trying to convince Vegeta to fuse. They
both throw a Generic Beam at buu at the same time. It looked
awsome. Two mighty saiyans side by side fighting for pride and their life
EDIT:
Almost forgot to add. When they are inside Majin Buu I remember
this one part when Vegeta and Gokou touch cheaks and put their
hands over each others and then do a huge blast. I dont remember
if Gokou says "Kamehameha" and vegeta says "Gallet Gun/FinalFlash".
So my guess it was the Big Bang Kamehameha Attack! lol
