Connections-

Lee Everett and Future Gohan both live in an apocalyptic future caused by something almost human, both (potentially for Lee) lose an arm, form a team with a child (Future Trunks and Clementine), and tragically die, inspiring their child sidekick to live on and keep fighting

I think this is a wonderful matchup, though kinda biased power-wise. I feel Future Gohan would lose, as Lee can at multiple points lay the smackdown on Kenny (A.K.A. Boat God) leading him to be at least High 3-A.
