Future Gohan with 1 hand ssj held himself against android 17 and 18 ( still died though
filler. gohan never actually stood a chance. with both arms, 17 stated he did not even need 50% of his power. gohan got cocky and got himself killed by a far superior opponent.
IIRC the androids (cyborgs really) in the future timeline were weaker than the ones in the main timeline
according to trunks, who you forget, at that point in time never actually fought them when they were serious as they never had any need to use their 100% skills on him
There is seemingly no 'perfect' way to truly say goodbye. So I gathered a bunch of them!
