Monstrosity

The Monstrosity is an understable Doomsday Discs distance driver built around a variable rim: two sides carry a wider rim and two a narrower one, so the disc reads as an oval from underneath.

Doomsday says the uneven weight distribution changes the mold's moments of inertia around the center axis and adds spin momentum on release, while the two rim widths also give players a choice of grip. Doomsday has not published four-number flight ratings for the Monstrosity, so none are listed here.

It is a relative of Doomsday's other variable-rim design, the Abomination, and is offered in Survival, Clandestine, and Glow Isolation.
