When I try to load any of the versions I get this:
Mod File: EpicFightMod-1.16.5-5.0.6.jar
Failure message: Epic Fight Mod (epicfight) has failed to load correctly
java.lang.NoClassDefFoundError: net/minecraftforge/event/entity/living/EntityTeleportEvent$EnderEntity
I think it has to be the problem with entities like Ender man, and Ender mites and I play with only one mod which is optifine.

Remove it. Optifine is very unfriendly to mods.

You should update the forge version to avoid this issue. The latest Epic Fight mod's matching forge version is 36.2.0
