History
The Coral Crab is an Atlantean object of power. Strange journeyed into Atlantis to take the crab after Namor refused to hand it over to Doctor Strange. Its removal unleashed the Brilliant One, a massive sea serpent that threatened the nearby Aquaria. Namor was able to recover the crab and returned it to its rightful place.[1]
At some point it ended up in Doctor Strange's possession again who added it to his Forge Inventory.[2]Properties
The powers of the Coral Crab are unknown.
