The new super saiyan transformation that's going to appear in the new Dragon Ball Z movie. Goku will be the one that achieves it (much to the disappointment of Vegeta fan boys.)
Goku fan boy: Dude, did you know that Goku transforms into a super saiyan god?
Vegeta fan boy: INCONCIEVABLE!!! Akira Toriyam needs to stop trolling Vegeta!
