Renown for his exceptional taste in sarcasm, Nickel is a critical character who is also snarky, churlish and ill-tempered. Nickel's most identifying trope is his trademark sarcasm, which he uses to convert mean thoughts in his head in order not to come off as rude and disrespectful to others. Though this strategy may not always work, Nickel still considers sarcasm as an art, and himself an artist. He carss deeply for his alliance, but has a hard time showing it.
