Hammersaur is a dinosaur/walking crocodile-like Bakugan with hammer-like hands. Anchorsaur is Hammersaur's opposite counterpart and the two are often used together.


Hammersaur is a bipedal reptilian Bakugan that resembles Anchorsaur. Unlike Anchorsaur, Hammersaur has large armored hands which are its distinguishing feature. It is almost always used with Anchorsaur because of their similarity. The similarity to Anchorsaur is probably evidence of being on the same evolutionary lineage but have split into two different evolutions.
