|This is what a living math equation look like?|
Dkrtzy RRR is a "bio-sentient" math equation. He was discovered by the mathematician Timph Rye. Timph found him while trying to see it would be possible for willpower to be "derived formulaically". He became the Green Lantern of Space Sector 188 under unknown circumstances. Mr. RRR's tendency of mind wiping people have been controversial among the Guardians of the Universe (although not enough to put him on supension or fire him). According to Green Lantern Tomar-Re, only the Guardians can be aware of Dkrtzy's presence.
He has a Green Lantern ring and lantern thus giving him the powers derived from the them. He can enter people mind and erase their mind. The latter is his preferred method of attack.
