Dr. Newton Zyme by @Kooshmeister (Bill Hiers)

The gentle biochemist Newton Zyme (that the "N" is for "Newton" is entirely Ignigeno and mine's invention) is certainly one of SWAT Kats' more underappreciated characters. In his first appearance Dr. N. Zyme was basically just a redshirt with a bad name pun, and treated to an implied gooey demise. Nobody mourned him or wondered whether he even died or not. Why would they?

When he reappeared in a second season episode explaining Dr. Viper's origins however, Zyme, despite limited screentime, revealed hidden depths and became one of the show's most well-developed characters in terms of personality, making it such a shame he was deprived of any future appearances by getting apparently killed off in the earlier episode.

Iggy and I find him adorable and sweet, and dislike his underuse in the show and his underrepresentation in the fandom and so heap as much attention on the guy as we can. Of course, the sadistic, evil Viper will always be our mutual favorite character, but good old Zyme is a close second.
