Gohan first turned ssj2 while fighting Goku in the hyper bolic time chamber while training for an instant while exhausted from training for 20 hours then he transformed into it again when cell killed android 16
yes gohan can turn super sayian 1 actually gohan can even turn super saiyan 2
gohan turns super saiyan 2 in episode number #170 It's actually DBZ Episode 185-Awakening
gohan was the first one to turn super sayain two
Z
super saiyan 2 gohan because if gohan beated cell and cell can beat broly so gohan can just do father son kamehameha
Gohan is stronger if goku is in his normal form but if they are both in super saiyan 2 form or if Goku is in super saiyan form then goku is stronger.
if gotenks made him made super saiyan 3 wouldn't matter because gohan would be as strong as gotenks super saiyan 3 plus teen gohan rulez
Actually Gohan goes super saiyan 2 in the episode The Unleashing.
Unfortunatly, no. You can do Father-Son Kamehameha with Super Saiyan 2 Gohan though. Actually you can just be super saiyan gohan and have super saiyan goten on your team -- dbz11
no the highest level he can go is super saiyan 2 the highest he can go is super saiyan 2 but goku can go super saiyan 4 and gohan has a great amount of speed.
160 is when he first went super saiyan 2 after training with goku (his dad) as a super saiyan 1 he was angry because cell killed so many people and killed one right in front of him so he got angry and went SUPER SAIYAN 2. P.S super saiyan 2 is the highest super saiyan gohan can do but in dragon ball AF gohan goes super saiyan 4 and goku goes super saiyan 50 that is all i can tell you.
i believe that the hair is bigger on ss2 and he will have more muscles on his body
