Nemesis: Martian Manhunter
Other Major Foes: Zook
Appearances: One comic story
A drifter who was zapped by the idol-head, then transformed into various creatures in search of a hidden artifact. Forms included a man-sized mole, a mammal with a steel screw power drill nose, a massive condor with spontaneously combustion feathers, a colossal winged caterpillar, and a giant weasel.
Lose: The Giant-Maker (0-4)
Nemesis: The Doom Patrol
Other Major Foes: None
Appearances: 20+ comics and a cartoon appearance.
Powers: Giant-sized hybrid human being made up of ambulatory wood, gemstone, and a dinosaur, allowing him plant control, claws, rock protrusions, super-strength and relative invulnerability.
Bio: Scientist and former student of Dr. Niles Caulder who fell into a vat and came out with the ability to turn into any animal, vegetable, or mineral, often several at once. Turning these powers against the Chief, Larsen was repeatedly beaten by the Doom Patrol, often through his own anti-decay ray.
As much as I hate the slaughter the Idol-Head has seen in these matches, often erroneously in my opinion, this one was based far more on similarly tortured titles than fairness. The Animal-Vegetable-Mineral Man devours the competition with his T-Rex head.
