Hammer

From Xenosaga Wiki

The navigator of the Elsa Von Brabant. Hammer has a vast knowledge of the net, and at times his opinion on how to fly the ship clashes with that of Tony's (the Elsa's pilot). In spite of the fact that its his job, Hammer doesn't seem to like scavenging the wreckage of starship disasters, like the wreck of the Woglinde. This character in Xenosaga resembles a non-anthropomorphic animal version of a similar character also named Hammer in Xenogears.
