Cosmic Seed

The Cosmic Seed is a fictional item featured in the animated superhero television series Marvel's Guardians of the Galaxy. It appeared in the pilot episode of the show, "Road to Knowhere".

Description
The Cosmic Seed is a powerful device of cosmic origin that is designed to accelerate life energy. It was contained within a CryptoCube, which was genetically encoded so that it could only be opened by someone with Spartax DNA.

History
The Ravager space pirate known as Yondu Udonta acquired the Cosmic Seed, and intended on selling it to the highest bidder. Before he could make a move however, he was captured by the Kree Pursuer Korath, who took it from him and delivered it to his master, Thanos. The Cosmic Seed was recovered by the Guardians of the Galaxy and brought to Knowhere where it could be identified and appraised by The Broker. Guardians leader, Peter Quill, who was half human and half Spartax was genetically capable of opening the cube. The power of the Cosmic Seed wreaked havoc on Knowhere, which itself, was the dormant head of an ancient Celestial being. The very structures on Knowhere began attacking the Guardians because of its proximity to the Seed. The Cosmic Seed also accelerated the life cycle of Guardians member Groot, who grew to twice his normal size and mass and raged out of control until his colleagues were able to bring him down.
