Mr. Onyx is Jim Hawkins' first officer in Treasure Planet: Battle at Procyon. Mr. Onyx is a Cragorian, and often helps keep Jim on the path of duty; his obligations as an officer of the Empire. Mr. Onyx is also known to be Mr. Arrow's nephew, as mentioned by Jim Hawkins in the beginning of Mission 1 in Treasure Planet: Battle at Procyon's Campaign. It is also assumed that Mr. Onyx is very tall, even taller than his uncle, since it is shown in photos in the game that Jim doesn't even reach his shoulder.
