Let's see...

There's The Von Strucker Twins. Then there are the Ultimate versions of Quicksilver and Scarlet Witch. The Hulk and She-Hulk. Dormammu and his sister Umar. Baron Mordo and his half-sister whose name I forget.
I can't remember the other instances, but there are/were a few others..

Totally off topic, but this reminds me of something I heard recently, claiming that Luke Skywalker is the ultimate redneck. They made a compelling case for it, too: he lived in a shack in the middle of nowhere with a yard full of junk, he bought broken stuff from the junk dealers, he lived with his aunt and uncle because his dad killed his mom, and he made out with his sister.

Captain CuCr.
Captain Carrot.
Captain Planet.
Captain Caveman.
Captain Stubing.
Captain Stingaree.

On a day when I have more energy, I might complain about all the joke answers; but yes, Captain Stingaree is indeed the correct answer. All yours, JTR.

All he needs is a six-pack of beer and one of them thar tee vees so as he can watch himself some nascar racing.

Are you sure that's right? Cause, I just tossed that in as the only captain made by DC with an "S" to start his last name. I needed the match for Stubing, who, as we all know, is far more evil.

I'll need a few moments to come up with something new to ask.

Stay tuned.

I'm sure that's right, and just to complete the "S" analogy, it was in Secret Society of Super-Villains number six.

And aren't you forgetting Captain Storm?

Argh......

I can picture the issue, but not the third captain. This wasn't when Captain Comet was still duped by them, was it? I'll guess Comet, even though I think this happened after he figured out they were badguys.

Aaaaaaaand I didn;t refrezh the thread before I posted. Dur!

Yes, I forgot Captain Storm. I can't even recall him now. I also left out Captain America, Captain Crunch and Kirk. There are too many captains in fiction.

However, there is this for you;

Who knew you'd be a comicbook character one day ?

True That!!!! The list of Captains could go much longer even, but I don't wanna go there.

As a side note, I did like a Geoff Johns Flash story where Captain Cold comments that he took the "title" of Captain to make himself seem more important...nice touch.

European. Doesn't count. Also, one's dead, so that can't contribute to "rampant."
Again, European, so it wouldn't count, except for Jeph Loeb coming in and ruining everyone's good time. I don't count it based on Loeb's involvement.
Shut up. No way. Marvel wouldn't.
Demons. Doesn't count.
Both European and dark wizards. Doesn't count twice.

I suppose (I hope?) we just have different ideas of the use of the word "rampant."

Dormammu and his sister are not demons. They are other-dimensional beings.

And, unless you're a pure blood Native American of pre-columbian ancestry, you have europeon blood in you.

Also, who said Mordo's sister was a dark wizard?

As for the Hulk, he has kids by She-Hulk in the recent storyline "Old Man Logan", in the Wolverine title. It's set in the future. And The Hulk says he had to force She-Hulk to be the bearer of his children.

Over on the Marvel Masterworks message boards, I suggested a trade paperback collecting What If? #4, Captain America #'s 153-156, and Captain America Annual #6; stories of the other men who've held the title. I suggested the title Captains Outrageous. If Marvel ever publishes this they owe me money. (I'd settle for three free copies.)

How about if instead, they send you a new issue retelling the origin of Captain America and how he and the Red Skull are actually half brothers, and that Bucky is the Skull's son and it's written by Bendis? And he and Joephisto autograph it for you?
