There is a fan animated series on youtube called Godzilla vs Ultraman.

To be honest I never heard of ultraman before but looking at this seems pretty cool

Rocketeer called, he wants his helmet back

adding to the other persons comment yea that late showa godzilla had this flabby muzzle like a bulldog and it was cute lol

awesome art! but why does godzilla have such an uncannily friendly barney the purple dinosaur face?
