I get that it's pretty much being suggested the reason why Bra is able to control SSJ2 is because of "Majinization" due to that being noted by Bra when talking to U16 and 18 Gohan but when it comes to using Majin Vegeta as an example for why Bra can now use SSJ2 without going insane, that's actually not a good comparison since it's not only implied but confirmed Vegeta already had SSJ2 in the Buu Saga before becoming Majin Vegeta

>Unless Salagir has his Vegeta aka Vegeta (U18) being based on the idea that Vegeta achieved SSJ2 through Majinization than okay, just throwing out Vegeta (Z) is actually suggested to have SSJ2 before he became a Majin
