Yes he was during the battles with Super 17 and Omega Shenron.
Mystic Gohan is stronger than SSJ2 Gohan.
ssj2 gohon
No, Mystic Gohan is far stronger than in his SSJ2 form.
Dabura is slightly stronger than ssj2 adult gohan. All we know that is teen ssj2 gohan is stronger than ssj2 gohan adult when he was a teenager power level =45 adult gohan ssj2 =40 dabura= 41.8 I think that dabura is slightly stronger than ssj2 gohan adult, but I also think that mystic gohan power level is slightly stronger than teen ssj2 gohan. I see his power level 48.5. Dabura is only stronger than gohan ssj2 ,1 and base in adult than I think that ssj2 teen gohan and mysic gohan are strongest forms of him and dabura is slightly stronger than ssj2 adult gohan.
SSJ2 teen Gohan pwn Broly but in movie 10, he wasn't SSJ2, he was in MSSJ.
Theme of Gohan
Well gohan when he was a teenager he went ssj2 pretty quickly so probably goten might go ssj2 never know surprises can happen.
Gohan nevers dies in GT
well that's tough to answer in my opinion it would be vegeta because vegeta is the exact same lvl as goku and goku is stronger than gohan therefor vegetas stronger
No, ssj4 is far stronger
Teen gohan power level is 12,000,000 and at full power 16,000,000 and ssj2 35,000,000
the first ssj2 was teen gohan in the cell saga after android 16 was killed, some people thinks its vegeta but he didnt go ssj2 until the majin buu saga
