Not to mention that since Suparar's anime and manga follow the same basic outline but deviate from one another, it's really confusing as to what is meant to be "canon" in regards to Super.
I think "it's a promotion for the anime!" Is a pretty weak argument against the manga. Like, did Goku go SSJG or not against Hit? Does in the manga, doesn't in the anime. Gotenks is SSJ3 against Beerus in the manga, he isn't in the anime. Little differences like that. I guess it's better to see them as two seperate existences.
