Gilliam Knight

Gilliam Knight (ギリアムナイト) is a knight-like robot in Mega Man 7 that is native to Shade Man's stage. While indoors, or when the moon is obscured, he is a knight on a unicycle wheel. Under the full moon, he turns into a wolf. This is not only a nod to werewolf legends, but when in wolf form, the Gilliam Knight strongly resembles the Weredog from Super Ghouls 'n Ghosts, which will lunge at the player.

In knight form, the Gilliam Knight is easily dispatched, but upon transforming to a wolf, it becomes dramatically tougher and considerably more dangerous.

Other media
Gilliam Knight appeared in Mega Man Gigamix and the Rockman 7 manga. Here, it is no different in appearance than its game counterpart other than the addition of a few bolts and different pupils in its wolf form which give it a very feral, threatening, and all-around vicious appearance.
