Shirokumachine GTV

Shirokumachine GTV (シロクマシーンＧＴＶ) is the large polar bear enemy in Mega Man 7. Appropriately enough, three of them appear in Freeze Man's stage. The first two simply roar and create icy spike balls to swat at Mega Man. The third one also does so, but also makes icicles fall from above.

Trivia
Shirokumachine is a combination of the words "shiro kuma" ("white bear" in Japanese) and machine.
