Well...ok...yeah. But....that's usually how it goes isn't it?
Killer Croc. Superhuman strength, regenerative power, nearly impenetrable skin, enhanced smell, etc.
Bane. Venom is the equivalent of superpowers since it gives him superhuman stength and of course he actually broke Batman's back so he can fight and DOES his own fighting (well he HAS had henchmen but when it comes to batman he usually prefers fighting him)
Ra's al Ghul. no real superpowers aside that the lazarus pit make him immortal, but he rivals Batman in fighting skills.
That's just off the top of my head, there's more.
Clayface - shape-shifter with enhanced strength, extreme control over his body's composition, and can not only disguise himself as anybody or anything he wants, he can also form various body parts into lethal weapons.
Manbat-half man half bat hybrid, high strength, expert flyer, sonar.
Solomon Grundy- Undead zombie with super strength, resurrection power (he can be killed but he gets better).
As Milk said these are the three I came up with off the top of my head, and there are indeed even more.
It's apparent Duuuuuude is clueless about the Bat, with his mention of King Tut, he's quite obviously stuck in the 60's.
