Gilliam Knight

Gilliam Knight (ギリアムナイト) is a knight-like robot in Mega Man 7 and 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 dog enemy from Super Ghouls n' Ghosts, which will lunge at the player.

Trivia
In the artwork, what was green sprite-wise is sky blue.
