Miserix (SMU)

SM Miserix was killed by Blair using Pumpkin Magic. Apparently, he had been placed in some kind of seal beforehand, which made the killing easier.

Absolutely nothing else is known about SM Miserix's life and death, because all records of it were deleted in BZPower's database crash. It is possible that SM Miserix was part of one of the Shattered Mirror invasion forces, which would explain how he met Blair, if their confrontation occurred in the Original Universe instead of the Shattered Mirror Universe.
