X5-471, 332231418471, or "Krit", is one of the twelve X5s who successfully escaped from Manticore in 2009.
Helping Max[]
Krit, along with Syl, joined with Max, Zack, Logan Cale, and a betrayed Lydecker in an attack against Manticore after the death of his sister Tinga.
Behind the Scenes[]
Krit was planned to reappear in "Love Among the Runes", but Joshua Alba was unavailable and a new character named Biggs was created.
Joshua Alba is Jessica Alba's real-life brother. It's not stated whether or not this is supposed to suggest any genetic relationship between Max and Krit.
