Great stuff, Bill 9000! Welcome back to the boards!
I really dig the original Crusader costume; that crazy mix of colors makes him almost as colorblind as Alan Scott!
The origin is cool, too; a nice mix of Clark Kent, Indiana Jones and Kent Nelson.
Odd to see a "second generation" hero actually older than his predecessor, but the costume's pretty cool, if a bit like a "negative" image of the Simpson's "Radioactive Man."
I see the Hank Pym influence in the SA Crusader, but with that fin on his head and the two-tone tunic he reminds me more of the GA Atom in his later costume. Those specs and the general vibe also put me in the mind of Marvel's 50's hero, 3-D Man.
The Bronze Age version is fun! He looks like he was designed by Dave Cockrum for the Legion!
Great stuff! You should be doing the Batman cartoon instead of the hacks they've got doing it now!
