Hello there gorgeous! Might I say you are looking as beautiful as a... rainbow?” - Rainbow Core

Rainbow Core, voiced by Harry Callaghan, is an easter egg character that can be seen midway through the game. He has a single line of dialogue where he flirts briefly with Mel before leaving on his management rail. After he leaves, Virgil seems flustered by his presence, asking Mel if she “(got) that core’s serial number”.
