Pompous Guy is a strange man from I Think, Therefore We Are.
First involved with Lady Shalice early in her story, Pompous Guy forces himself upon her, curious about her unique features. Determining that she is only an animal, he claims her as a pet of his own. When she counters that she can do magic, Pompous Guy doesn't believe her, forcing her to levitate some of his furniture into the ceiling. Pompous Guy then sells her off to Block of Man.
The two encounter each other again, this time in a diamond mine. Suggesting that the owner of the mine is Pompous Guy, he screeches his head in panic when the mine erupts in flames, giving Lady Shalice enough time to make her own escape without notice.
