Similarities between Marvel & DC characters

Which characters were the inspiration for other similar characters of different publishers?

Namor > Aquaman is an obvious one.

Green Arrow > Hawkeye. Also an obvious one.

Green Lantern & Green Lantern Corps > Nova and Nova Corps (this one's just my opinion but they really do share some resemblance)

DeathStroke > Deadpool. Come on. Ones name is Wade Wilson, the other's is Slade Wilson. And they look identical enough that one could be wearing the others alternative costume.

Swamp Thing > Man-Thing. Both made their debut in the same year so I forget which one was the original idea but I like them both so I don't care.

Catwoman > Black Cat

Alfred > Jarvis

Who else?

Hmm... Let's see:

Superman > Hyperion

Superman > Sentry

Superman > Gladiator

Superman > Blue Marvel

Superman > Wundarr the Aquarian

That's a lot of Superman rip-offs.
