I'm a big fan of Tom and Mark so this is like Christmas and Birthday rolled in one...

Batman meets Sgt DAD from Combat Jacks - by Jason Baroody and Mark McKenna

That's a definite first time ever crossover!
Batman and Sgt DAD (from Mark McKennas creator owned comic "Combat Jacks") are waiting for the next attack of the Jacks.
I sure hope at least one of them turns around soon...  ;)

Batman vs Juggernaut - by Victor L. Castro and Mark McKenna

Pencilled by Victor L. Castro (here's his deviantart page) and inked by Mark McKenna (here's his website).
I had a lot of fun working with Victor and Mark on this one (okay, they did the work and I butted in with an idea a few times :)
In the previous post (which should be right beneath this one or here) there are a few work-in-progress scans of this commission, look it up.

The road to Batman vs Juggernaut by Castro and McKenna

This was the first rough sketch by Victor.
Juggernaut was on top of his list of characters to put in a 'Batman and...' commission and I liked the pair-up idea immediately.

One of the work-in-progress sketches by Victor.

The final pencil art. This was copied by Mark McKenna to make an inked version.
