The Origin of Dr. Viper
He was planning to steal the formula, Commander. And when it all spilled on him, the shock to his system must’ve been too great. - Dr. N. Zyme
Dr. N. Zyme and his partner Dr. Elrod Purvis co-develop Viper Mutagen 368. While attempting to steal the chemical, Purvis spills it on himself and seems to die, but the flawed formula causes him to revive as Dr. Viper.
With SWAT Kats nearing its end, the mystery surrounding one of its major villains is finally solved in this flashback story.
Dr. Zyme (who was killed in “The Giant Bacteria”) and his partner Dr. Elrod Purvis co-develop Viper Mutagen 368, a regenerative growth formula that the “idealistic fool” Zyme wants to donate to Megakat City but the greedy Purvis wants to sell to the highest bidder. While attempting to steal the chemical, Purvis spills it on himself and seems to die, but the flawed formula causes him to revive as the murderous mutant we all know and hate.
And when Viper endangers Zyme, Mayor Manx, Deputy Mayor Briggs and Commander Feral with his giant mutant mosquitoes, only the SWAT Kats can rescue them all. Easily the best of the SWAT Kats shorts, this is so densely packed with characters and subplots that it easily could have been expanded to a full-length episode. But then, how could we live without “Volcanus Erupts!”? A-.
Animato summary written by Mark Lungo
Burke knelt down and pulled back a ratty-looking rug, revealing what appeared to be a kathole cover or a hatch of some kind. Murray blinked.
"It looks like a hatch."
"I know," Burke replied. "What I don't know is what it's doin' in the middle of the floor here in their pad."
Murray scratched his head under his cap, thinking. He suddenly snapped his fingers. "I know what it is!"
"What?" asked Burke.
"This place used to be a base or something like that back in Mega War II, and it had a big underground bunker and stuff like that," his brother said. Burke's eyebrows furrowed under his cap. "I used to ta' have the skematics of the place from the city hall of records, but I lost 'em."
"So you're sayin' there's a whole underground complex under our feet that nobody's been down to in over fifty years?" There was wonderment in Burke's voice.
"Yup," said Murray. "And I'll bet ya two cans of tuna that that's where those jerks Clawson and Furlong are hidin'!"
