Ship is a small Galvanic Mechomorph that first appears in "Pier Pressure". Though it possesses the Mechomorph capabilities of fusing with and controlling machinery, its personality is more akin to a dog than anything else.

In "Pier Pressure", his master's spaceship crashlands on Earth and Ship is sent to find help. It isn't long before it detects the Omnitrix on Ben's arm and tries to get his attention. However, in doing so, it destroys much of the Pier and kidnaps Julie. Following Ship, Ben finds the downed spaceship, and realizes what Ship is trying to say. After Ben rescues the owner, Ship stays behind with Ben (because, according to its master, its taken a liking to Ben). Towards the ending, Ship ended up chasing a truck leaving Julie and Ben alone. Ship is now Julie's pet dog. He can turn into a ship that is the teams main way of space transportation. In one episode Ship's owner wants Ship back and sends the Rebo brothers to capture him. In court, Ben and Kevin win and Julie keeps Ship. In the same episode, to fight the Rebo brothers, Ship mergest onto Julie, making a super-powered kind of suit around her. Ship is seen changing into a variety of forms.
