I don't know, it just sounded like a good name for the kid-friendly version of the Justice League. Or a smaller version of it that could fit on my piece of paper that I drew too large on. This started as a I want to draw in a simplified "Mary Blairish" style drawing of Wonder Woman, then I just started adding to it till I had a team. The Atom is only in there because I didn't have enough room for Aquaman or someone else. Just for fun.
EDIT: I agree, Batman HAS to be in there- and now he is. I added a quickie of him and moved The Atom.
