Though GT is a very overpowered series, Vegito would still be significant in the mix.
Hypothetically, Vegito can turn SSJ2 (Both Goku and Vegeta can turn SSJ2) and SSJ3 (Gotenks turned SSJ3 though Goten and Trunks were only ordinary SSJ). Now, if this SSJ3 Vegito, End of Z (stronger than the Buu Saga counterpart) would go 1-on-1 would any GT Villain, which ones do you think he would be able to beat?
Minor Villains (Ledgic, Lord Luud, Cardinal Mutchy Mutchy)?
Golden Great Ape Baby Vegeta?
Each Shadow Dragon?
What are your thoughts?
