Shugoki + Gladiator = "Ornstein and Smough".

Centurion + Gladiator = "The Pasta Bois".

Lawbringer + Peacekeeper = "Good Cop/Bad Cop" (which is which? No one knows!).

Highlander + Aramusha = "Jack and the Scotsman".

Raider + Warlord = "Ledge-Lord Lunacy".

Conqueror + Warlord = "Bumper Cars".

Lawbringer + Conqueror = "Supervised Probation".

Any more ideas?
