unreal inlet
(I really want some feedback for this) 
So some of the ideas I thought about for his legendary start emote would be:
Gohan breaking out of Raditz’s Space Pod
(Kinda like Broly’s emote)
Kami’s ship landing with Gohan hopping off
(Kinda like Trunk’s emote)
Gohan getting his potential unleashed from Grand Elder Guru then leaving, landing on the ground
Gohan rushing in to save Dende from a random Frieza Soldier (Soldier gets kicked far off), next scene is Gohan telling Dende to “hurry” as in to run
That’s all the ideas I can think of right now, but please tell your ideas by commenting and what you think of mine!
