He is brown and small with a grey stomach, mouth and some white hair.
He was the best friend of Decka. When Decka vanished, Orb did what his parents advised him to do in case of trouble and called Max Tennyson, who then sent Ben, Gwen and Kevin to help. They found out that Mayor Coleman had imprisoned Decka and had fed him meat. Mayor Coleman was not aware that when Decha's species consumes meat, they turned into their feral forms, and as a result Decka caused widespread destruction before Echo Echo returned him to normal. Orb and Decka then returned to their planet, Decka vowing never to return to Earth ever again.
