From Bulbapedia, the community-driven Pokémon encyclopedia.
Infi (Japanese: インフィ Infi) is a character who appears in Giratina and the Sky Warrior.
She is the program that pilots the Megarig. Her name is taken from the word "infinity" and her design incorporates lemniscates.
There are holograms of her spread throughout the airship, may be so that she could scout the Reverse World, without the need to get out and report anything to Zero.
During the ending credits of Arceus and the Jewel of Life, it was revealed that surviving data of Infi was recovered from the Megarig by Newton Graceland after the machine was destroyed.
