Rai is Thor’s twin brother and was abandoned together with Thor at Chimera. He is the weaker twin and Thor must go to great lengths to protect him. He is slightly more chubby than Thor. Both Thor and Rai are noted for having blue-gray eyes and silver hair; Zagi finds this to be highly unusual, despite the colony's abilities of gene-manipulation. <br /> <br /> (source : wikipedia)<br /><br />
