Harrison Chase was an eccentric millionaire whose primary hobby was botany. In its pursuit, he assembled the world's largest collection of plants and disdained humanity in favour of plant life. He even composed music for the plants in his greenhouse.
Chase was obsessive about his plant collection. He deemed himself the greatest collector of plant life and considered it the most helpless and beautiful thing in the world.
Chase learned from a government official, Richard Dunbar, that a Krynoid pod had been found in Antarctica. He bribed Dunbar regularly for information. Chase sent his best man, Scorby, and a scientist, Arnold Keeler, to steal it.
The Krynoid came into his possession and it infected Keeler, who slowly changed into a Krynoid himself. Chase would not allow Keeler to get medical attention. He accelerated the process by feeding it and tried to study the plant's biology.
The creature grew bigger and more powerful. Chase began photographing it when it attacked him; he became psychically linked with it, and began to aid it in its plans to destroy animal life and become the dominant lifeform on Earth.
