Cobalt Metroid

Cobalt Metroid is a user on The Metroid Clubhouse Forum. He also participates as a character in The Epic Quest Saga. Technically, the user was responsible for starting all of Epic Quest, for he was the topic poster of Random Battle Royale.

Ye Olde Battle Royale
As previously stated, Cobalt originated the thread, and was its first poster. It is believed that the character Cobalt Metroid orchestrated the entire Battle Royale, for some unknown, twisted purpose. He opens by smiting with a rubber chicken (BR:1:1). He was also apparently allied with Jacen Solo.

Later, he brings "zombification" into the battle by resurrecting as a zombie and zombifying others. This plays a significant role (if you can call anything in that thread significant).

After being killed in conflict with Jacen, Cobalt possesses him. Jacen killed himself, killing Cobalt, and he re-materializes and arms himself (BR:2:3). He tries to hit on Samus and is swiftly rejected.

During the X Parasite war, Cobalt climbs a tree (BR:2:12). He is destroyed along with the Solar System when The Baker blows it up.
