Krabo was originally a human guy named Jacob. Jacob's boss ██████ accused Jacob of murdering 9 customers at the ████████ that Jacob worked at. Jacob was found guilty in court and taken to ████████ High Security Prison. Then Urbanshade went by selecting prisoners to take for experimentation. Jacob was one of the selected and taken to the ████████ Scientific facility along with Sebastian Solace. Then the scientists at Urbanshade experimented on Jacob by mixing his DNA with crab DNA., Pufferfish DNA, and ████████ DNA And because of memory loss, he forges his new name to be Krabo. Then Krabo and Sebastian got thrown into a submarine to go to the Hadal Blacksite for further experimentation. Then Sebastian and Krabo made a containment breach at the Blacksite and caused Urbanshade to send thousands of expendable ████████ to retrieve the ████████ that powers the Blacksite. Later, Krabo was found innocent, he did not kill the 9 people that he was accused of, yet he was never informed of this. Then he was sucked into a portal leaving Sebastian behind. Then he broke out, stole prince ████████'s grimoir, and started surfing the cosmos of the omniverse, searching for Sebastian ever since. He has made many allies along the way such as ████████ and ████████, thus increasing his chance of finding Sebastian and stopping Urbanshade from sending more expendables to the Blacksite and stall retrieval of The ████████.
