Doctor Finitevus was an Echidna from the city of Albion, and one of the last known surviving citizen of that city by birth. He was transformed into an Albino Echidna after using his creation, the Chaos Siphon Suit in an attempt to drain Chaos Knuckles' power and restore him to normal. After this, Finitevus's mind has slowly transformed into that of a villainous mad scientist, who betrayed his city to the Eggman Empire. When he was first discovered by Sonic the Hedgehog and Knuckles the Echidna, he was working for the Dark Legion and was subservient to Lien-Da. Shortly after this however, Finitevus left his position as a Legionnaire and began enacting his own schemes.
