Battling Boy's father fighting the "Dragosaur".
In Batman Year 100, I had room for a couple of long fight sequences, but I felt cramped even with 200 pages. This fight scene from BATTLING BOY alone is about 50 pages. It's liberating to have no page restrictions. I wish Kirby could've had 50 pages for one fight scene, imagine what he would've done.
The extended cinematic sequence is one of the best gifts we've inherited from manga.
