Gator’s real name is Gerald, but he doesn’t mind being called ‘Gator.' Everybody calls him that. Gator has a calm, grounded personality and an adventurous spirit. He has been designed to work in the high mountains in a land far away. He longs to travel and is excited about going to sea and this makes him a hero in the eyes of Percy, who sees in Gator the brave engine he would like to be.
Gator's nickname comes from his unusual shape and look of an alligator.
