In the battle against Universe 11’s Toppo, Vegeta takes his power to new heights in Dragon Ball Super episode 126. It’s a form of Super Saiyan Blue, but the hair, the eyes and the aura display a more intense blue color compared to the standard Super Saiyan Blue. The form has had a few names bounce around by fans including Super Saiyan Blue 2 and Super Saiyan Blue Limit Breaker, but the official name hadn’t been revealed until recently.
The official name is actually Super Saiyan God Super Saiyan Evolution (or Super Saiyan God Super Saiyan Shinka in Japanese). Quite the mouthful! The information comes from the Japanese card game, Dragon Ball Heroes. It’s possible the name could be changed in the future, similar to how Super Saiyan God Super Saiyan (SSGSS) was renamed to Super Saiyan Blue or just Blue in Dragon Ball Super. The name ‘Super Saiyan God Super Saiyan’ was not mentioned in the Dragon Ball Z: Resurrection F movie itself, where the form made its debut, but rather that name was first revealed as part of marketing for it through Shueisha’s Weekly Shonen Jump Magazine. We can see Super Saiyan God Super Saiyan Evolution being renamed to Super Saiyan Blue Evolution or just Blue Evolution.
As you may have already noted, in addition to the more intense blue color, Super Saiyan God Super Saiyan Evolution contains now visible pupils (similar to Super Saiyan 3, Super Saiyan God and Ultra Instinct). The light particles of the aura now display a stronger sparkle, being bigger and taking the form of four-pointed stars, as well as the subtle yellow glow of the Super Saiyan Blue disappearing completely. You can take a look at visuals of both the original Super Saiyan God Super Saiyan (Super Saiyan Blue) and Super Saiyan God Super Saiyan Evolution below.
