Who is Ronan & The Sentry?

I know both of them are a part of the New Avengers but who are they? When was their first appearances, in which comics, what are their super powers? I am deffinitely not new to comics but I am new to these two characters.

Thanks that clears everything up for me, I can't believe the sentry's first appearance was in Venom: The Lethal Protector #2, I had seen him before & didn't even know it. Thanks again.

Two lame-ass characters who "officially" members but only make guest appearances in reality.

I just found out Sentry killed Carnage, WTF! He killed Carnage! That can't be!

I still think you are a little confused here. On the link that thekahn put up, you should look at Robert Reynolds. He's the Sentry in New Avengers and with his mini now. I'll post a bio of his so you can check him out.

And I happen to think that both Ronin and Sentry are wonderful characters with a lot of potential. Hopefully Sentry will make his presense known more in the next arc.

Not a battle. Stuff like this goes in the comic forum. Or better yet, in the "Comic Book Questions" thread in the comic forum *hint-hint*

Moved.
