Hector McGill is a character from Attack of the Alligators!. He is the assistant of Dr. Orchard. They live in a lonely house on the Ambro River. Orchard has found a rare plant (Sidonicus Americanus), that grows only in this part of the Ambro River. From it, Orchard has developed a food additive called thermine, which greatly increases the size of animals fed with it. This discovery obviously has great potential as a solution to the world food shortage, and even greater financial implications.
