Proto Nemesis 170RD

Unreleased Proto Nemesis (known as Prototype Nemesis in the Ultimate Bey Ta Stadium) is the prototype version of Diablo Nemesis. It will be released with the Ultimate Bey Ta Stadium on October 23, 2011 in Japan.

Design
Prototype Nemesis, as its name implies, it is a prototype of the currently unreleased Nemesis Beyblade. Although it cannot be disassembled, it features a Fusion Wheel that appears to look very sturdy and thick with a somewhat resemblence to the Gravity and Leone wheels. It appears to have skull like designs on it and will be silver in colour. It also does not appear to have a Face Bolt.

Ultimate Bey Ta Stadium
The goal of the Ultimate Bey Ta Stadium is to deplete Prototype Nemesis' spin entirely. The Stadium has a spinning center, and Prototype Nemesis is placed on it. Once placed, the center will begin to spin and this Prototype Nemesis follows suit. When the Beyblade hits Prototype Nemesis, Prototype Nemesis will get sent out of the spinning center but then start to come back to it due to being attracted to it like a magnet. Prototype Nemesis will keep doing this until it stops spinning.
