She’s so adorable and cute in that form and many other super saiyan forms.

The Power of Friendship mixed with Divine Ki.

Gloriosa: W…what is this form?! How could you possibly have become so much stronger?!?!
 
Twilight: Well, it’s quite simple when you get down to it. You see, while I was training under Queen Faust, I discovered a way to infuse my Super Saiyan God Super Saiyan transformation with the magical energy of Rainbow Power. Not only does this form increase my strength and ki power to unprecedented levels, but like the other God forms, it doesn’t prevent me from using my magic; in fact, it actually enhances my magical abilities!
 
Sunset: I-impossible! A Super Saiyan transformation that amplifies the user’s magic…?
 
Twilight: You know, I just realized I haven’t given this form a name yet. Let’s call it…Super Saiyan Rainbow. Now then, how about we test out just how powerful it really is?
