Some of those listed are in fact Easter Eggs or jokes. But where's a gigantic cyborg Super Mutant named after Dirty Harry? You mean Harry the Super Mutant? He's not a cyborg, nor is he any reference to Clint Eastwood. Harry is a popular name.
The Lieutenant is a cyborg, but why do you consider him "fun"? To me he's actually more of a threat than the Master himself. Or are you actually refering to Harry calling him "Lou Tenant"?
