Notable Attacks/Techniques:

- Crystal Valley: By violating the reality of Earth ORT can transform his surroundings into the environment of Mercury. It alters everything into crystalline-like structures, including living beings as trees. This is a beautiful yet frightening visage that can drive any human insane just by looking at it. The Crystal Valley is far superior to Arcueid's Marble Phantasm in power. Yet, for the ORT this is an ability as natural as breathing.

Other: Despite Mercury being the smallest planet in the Solar System ORT is probably the strongest - and the laziest - Aristoteles in the Nasuverse. Interestingly, the ORT has no real appearance in any Type-MOON works yet. The profile above is mainly based on the background information found in databooks and logical powerscaling.
