As Mega Blastoise, it develops two smaller shells over its arms, each with their own water cannon. The two cannons on its back are replaced by a single, central water cannon of greater size. This cannon extends forward over Mega Blastoise's head and is said to have a blast range of over 6 miles (10 km). Small ridges develop over its now-red eyes and extend to its ears. The larger cannon can retract into its shell. The ears angle slightly backward and there is a small point on its chin.
