Yes, Disaster has an alternative/secondary name (Walter: But the name isn't said/used by my other characters except Sebastion).

Sebastion is a new character of mines I've been planning out. He's a musician who plays the piano, harp, cello, and triangles. He's good friends with Disaster but depends way too much on him. By the way, he's an Austrian black and tan hound.
#DisasterCC #SebastionCC <- I wanted to put Sebby but that will be confusing #Dog
