Greeeds are fictional creatures from the Japanese tokusatsu series Kamen Rider that debuted in 2011. They are known for their unique ability to absorb and utilize the desires of humans, which they use to gain power and transform into formidable beings. Each Greeed is associated with a specific desire, such as greed for wealth or power. In the series, Greeeds are often depicted as antagonists, challenging the protagonist, Kamen Rider OOO. They can create powerful monsters called Yummy from the desires they absorb, leading to conflicts with the hero. The Greeeds' quest for power ultimately serves as a central theme in the storyline.
