Prowl

Prowl (Cervo in Canada, Pantera in Italy) is an Autobot of many virtues - he is quiet, competent, loyal, and possessed of almost endless patience. When Optimus Prime appoints Prowl a task, he can be guaranteed that it will be completed to the best of Prowl's ability. Prowl is not given to speculation or estimation - the only realm in which he will work is that of the proven fact; if he can't explain it, he will not believe it. He hates doubt, and strives to make a situation as simple and logical as possible, purging excesses of concern from his mind by going to Optimus Prime for assurance. Prowl is friendly, but only as a listener; as a talker, he is not so sociable, entering a conversation usually only when someone makes an unreasonable remark, and demanding an explanation.
