The Exiles then discover there is a second team conscripted by the Timebroker, Weapon X, whose missions typically involve killing or maiming innocents and heroes. The two teams join forces to rescue a group of children from a Sentinel prison camp. However, the teams are told the second stage of the mission is to kill one of the children – David Richards (son of Rachel Summers and Franklin Richards) – who will apparently grow up to become a powerful supervillain. Weapon X is willing to kill him, but the Exiles are not and the two teams fight until the Timebroker intervenes. Sabretooth (of the Weapon X team) agrees to stay behind and raise David Richards himself.
