Vegeta in 63

[Void]

Vegeta's aura has a clear change when he starts beating up on Black, there's even lightning around him at the end. I assume Super won't bother explaining, but do you think this is just to show he's more powerful or did he actually transform into some pseudo SSj2 Blue form? Another thought that I've had is that he "mastered" the form in a way similar to Goku and Gohan did for SSj in their first RoSaT trip before the CG. What do ya'll think?

There's been lightning for SSJB and SSJR (which has a similar looking aura). I don't think he achieved any sort of new form, so much as just got stronger.

I thought that's just SSJB's ordinary aura.
