Superheroes for Kyle

My son in law Kyle is a superhero aficionado.

Superman versus Batman right?

But who’s the hero in the lower right-hand corner?  I really have no clue, yikes!

Help! I was hoping to send Kyle a clever note with these buttons but if I don’t know who the lighting bolt hero is I’ll let him down….

Flash Gordon? I think Flash Gordon had lightning bolt ears?

P. S. Don’t ask me why the upper left-hand button is missing it’s too long of a story ….
