Shirokumachine GTV

White Bear Machine GTV (シロクマシーンＧＴＶ) is the large polar bear enemy in Mega Man 7, and appropriately enough, it resides in Freeze Man's stage. What's odd is there are three of them (unlike the traditional two large enemies in most Mega Man games). The first two just 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
Shirokumashīn is a combination of the words "shiro kuma" (white bear) and "mashīn" (machine).
