All month long we will feature brand-new Cool Avengers and X-Men Comic Book Moments in celebration of their fiftieth anniversaries this month. Here is an archive of all the past cool comic moments that I've featured so far over the years.

Today we look at Captain America making his Silver Age debut in Avengers #4 by Stan Lee, Jack Kirby and George Roussos...

The issue opens with that rascal Namor throwing a block of ice that a bunch of Inuits were worshipping into the ocean. As it turns out, that block of ice contained Captain America, suspended in animation!

As the ice melts, the Avengers' submarine (they were in the area tracking Namor) comes across Cap and then we get one of the most awesome re-introductions you'll ever see...

How much of a stunning example of Captain America's coolness is that? He wakes up twenty years in the future and he basically just has a quick freak out and then he pulls a Fonzie and suddenly he's totally calm.

Then, for good measure, he's like, "Hey, bunch of powerful looking folks I just met, I bet I can kick all of your asses." And then he pretty much DOES JUST THAT!

That "try to conquer me" panel is just a stunning display by Kirby. So much casual awesomeness there.

It's three pages and Captain America has already solidified himself as an awesome addition to the team. What a great story by Lee, Kirby and Roussos! As for THE moment, I dunno...I am partial to the "try to conquer me" panel, but I can see the "Who am I?" sequence of panels as being "the" moment, as well.
