Origin

After the destruction of the Nova Corps by the Annihilation Wave, the Xandarian Worldmind secretly sought out new recruits during Richard Rider's sleep hours. Morrow, a Mephitisoid, was among those first selected to be a new Nova Centurion. Soon after his selection, the Worldmind transmitted an emergency signal as the result of nearly being destroyed by Galactus. Morrow joined with the four other Centurions to have been selected thus far -- Malik Tarcel, Qubit, Irani Rael and Fraktur -- and tracked down the Worldmind's signal.

Earth proved to be the destination. Morrow arrived with his fellow Centurions at the tail end of the Skrulls' attempted invasion. They fell right in line behind Richard Rider, the Nova Prime, in helping keep the peace after the invasion's aftermath. These efforts included dealing with a hostage situation perpetrated by the Serpent Society, during which Morrow enjoyed launching Anaconda through the roof. He later followed the lead of Robbie Rider in apprehending Dragon Man.
