This form exceedingly surpasses its predecessor, Super Saiyan Blue 3. Goku Black has his own version of the form is called Super Saiyan Rosé 4, which possesses a different hair color due to him being an actual god with natural godly ki. Form mainly used by (MY FUSION OC's) Zenick and Zackith, stronger then anything in time or space Gallery.
This would put Super Saiyan God and Blue far, far above Super Saiyan 4 in terms of a strength increase though. Goku's base form, in GT, is considerably above where Goku's base form in the Buu arc and the Battle of Gods arc is, yet the guide indicates that Vegetto's strength is at or above Super Saiyan 4 Goku's strength. However, one moment of Dragon Ball DAIMA's final fight suggests that Super Saiyan 4 may be similar in power to Super Saiyan Blue.
Dragon Ball DAIMA's final episode, "Maximum," sees Goku return to his Super Saiyan 4 form to battle with Gomah, who is growing increasingly strong thanks to the power of the Evil Third Eye. Description Combining both the appearances of Super Saiyan 4 and Super Saiyan Blue, Super Saiyan Blue 4 gives the user a godly blue aura and engulfs their skin in bright blue fur. The user's hair slightly grows just like an SSJ4 and the form also creates a red outline around the user's eyes.
Games, print, and anime a like, most of them conflict with one another but there is a common thread amongst them. SSJ4 and Blue are different animals. Just like how SSJ4 was meant to be a different type of SSJ transformation to begin with in the first place.
Blue is the more powerful form, I'll get that out of the way right off the bat. Goku's SS4 form is a fan favorite, but how does it compare to Blue Evolution? We explore the strengths and weaknesses of each transformation and decide which is the strongest. Super Saiyan 4 (超スーパーサイヤ人じん4フォー, Sūpā Saiya-jin Fō) is an advancement of the Super Saiyan and Golden Great Ape forms that first appears in Dragon Ball GT, with an updated incarnation of it later appearing in Dragon Ball Daima.
As part of the Great Ape branch of Super Saiyan transformations, the Dragon Ball GT incarnation of the form is separate from the standard. The Super Saiyan 4 of the Grand Tour How Goku achieved Super Saiyan 4 in Dragon Ball GT was vastly different from how it happened in Daima. 4 cause it feels like a step towards/an in between of the Giant Ape form.
I remember reading the rational behind Super Saiyan God just being Goku but red was that his different forms were getting away from Goku's base design and this was a sort of course correction. I feel like Blue kind loses that by just being Super Saiyan but blue. Super Saiyan 4 is the superior form in every way.
It obviously has a far better visual design, and also has much more meaningful integration into past lore for both the Saiyans and Goku personally.
