Tong
Tong is the self-proclaimed greatest Asiatic overlord since Genghis Khan. He created the Great Red Brain in "Marvel Family" #80, and apparently died when it fell from its casing onto him. But he returned in "Marvel Family" #82, having devised a way to grow animals to enormous size. He first uses a battalion of giant rats then giant pythons and kidnaps the soldier Hank, but the Marvels use the dog Yank to track Hank while disguised as peasants. They get to Tong's base, an old house, where they are knocked out from behind by a guard whose attention is aroused by the barking of Yank, chained by their thumbs, and gagged. They are nearly eaten by a giant lizard, but while Yank distracts it, Freddy removes Billy's gag with his leg brace, allowing him to free the others as Captain Marvel, although the lizard apparently kills Yank with a deadly bite. They defeat Tong's lizard battalion which is being dropped by parachute and discover Yank is still alive, allowing him to be saved.
