I found some worthy candidates to research your find, Lopehole:
The Aftermath (1982)
tagline; Hell in the Aftermath; who will survive?
Mad Max‘s bizarre mutant biker-gang leader was (strangely yet memorably) called Toecutter. The Aftermath has a gang of mutant weirdo bikers led by B-movie god Sid Haig’s ‘Cutter’. Despite the utter lack of originality, the story (slightly influenced by Planet of the Apes: astronauts return to Earth to find it a post-apocalyptic wasteland inhabited by gangs of violent criminals et cetera) and direction actually make this a very watchable B-movie.
Endgame (1983)
tagline; For An “Endgame” Champion In The Year 2025, There’s Only One Way To Live. Dangerously
‘Escape from Mad Max 2’ again; this film shares many parallels with the later The Blood of Heroes (see below) and looks forward to The Running Man, but is much more fun than either. Telepathic mutants, violent game shows, warriors, what’s not to like?
Stryker (1983)
tagline; After the holocaust, nothing matters but survival also, perhaps better; The Odds are a million-to-one. And Stryker is the one.
Uninspired taglines for an uninspired movie; Filipino exploitation master Cirio H. Santiago (TNT Jackson, Nam Angels) directs this opus in which, after the inevitable apocalypse, the world is running out of water (of course), and a group of Amazons guard the last known freshwater spring but are attacked by a gang of blah blah blah, until moody, monosyllabic tough guy “Stryker” turns up to help them out. You know the rest.
