He is quiet, competent, and very loyal, but perhaps his most valuable trait is his almost endless patience. Once Prowl is assigned a task, he will keep at it until it is accomplished. He works with proven facts, not imagination or guesses. If he has any doubts, he will radio Optimus Prime, his commander, before proceeding. He hates doubts in any form, and he strives to make everything he encounters reasonable and logical. He believes it only when he can explain it. On a personal level he is friendly, but not too sociable. He's a listener, not a talker, unless someone says something unreasonable. Then he will demand an explanation.
