Often wears cowboy hats and sleeveless plaid shirts when he makes public appearances.
His phenomenal vocal range
Often does multiple voices when he does voice over work.
Provided four distinctly different voices for four characters on Beast Wars: Transformers (1996) - Predacon flier Waspinator, Maximals Rattrap, Dinobot and Silverbolt, more than any other actor provided for the series.
Silverbolt, the Fuzor Maximal he voiced on Beast Wars: Transformers (1996), was called "Grifo" in some European countries.
One of the few Beast Wars actors who didn't completely hate working on the much maligned sequel series Beast Machines (1999), McNeil later recalled that during recording sessions his colleagues, such as Garry Chalk, would often flip out in anger over the changes made to their characters.
Auditioned for the Predacon Fuzor Quickstrike when he auditioned for Silverbolt during the second season of Beast Wars: Transformers (1996) and was certain he would be cast as Quickstrike only to be surprised that he was chosen only for Silverbolt instead, which he said was actually the most difficult of his Beast Wars characters in part because, ironically, he was asked to play Silverbolt with roughly his normal voice.
