He then disappeared from view to fight a war in Otherworld against the demonic Goat, who had attempted to subjugate the multiverse. His brother Jamie, now cured of madness, was a key ally and Brian tried to cajole Betsy into joining as well. Relations with his sister deteriorated as the Corps tried to put her teammate Fantomex on trial for murdering a young Apocalypse, arguing that it was still a crime to kill a child for what they may become. Ironically, in the end it turned out the Goat was a future version of Jamie who had been turned evil and Betsy, who had been forced to sacrifice her emotions to win in battle, stopped the villain by killing the contemporary Jamie; she then berated Brian for leaving the choice to her. He was left bitter by the loss and estranged from his sister.
