In his first movie, Godzilla Raids Again, Angilas was Gojira's enemy, but in his later films Angilas become Gojira's friend and battled against the invading space monsters. Angilas had no fancy breath weapon, just sharp teeth, claws and a body coverd in spikes, this never stopped him from taking on larger, more powerful daikaijuu. This is probably what makes Angilas so popular.
