leader, Sergei. The Arctic Incident In Artemis Fowl and the Arctic Incident, he has used the gold he stole in the first book to buy himself a fancy apartment in Los Angeles, under the alias Lance Digger. He quickly returns to his old ways, and becomes a thief known as "The Grouch", after another certain personage, famous for stealing one of every Academy Award trophy. After being 'found'/abducted by Artemis and Holly Short, he helps them break into Opal Koboi's laboratories (which he helped design with his cousin Nord), in exchange for a two-day head start, which he takes as soon as the mission is over. The Eternity Code In Artemis Fowl and the Eternity Code, he is initially working for the Antonelli family as a "monkey" (which means someone who is good at breaking into places) under the alias Mo Digence, but intentionally foils a plot to kidnap Artemis to get the secrets of the C-Cube, and subsequently assists him in breaking into the Spiro Needle to steal back the C Cube. After this, Artemis Fowl helps him by changing the date on his original search warrant, rendering all further convictions void. Artemis gives him a gold medallion which is actually a computer disc with information to help Artemis recover his memories after the mind wipe. The Opal Deception In the fourth book, Artemis Fowl and the Opal Deception, he is en route to his hearings when he hears of Commander Root's death and escapes from and steals a LEPrecon shuttle, knowing that Holly couldn't have committed the murder and regarding Root as a 'sort of' friend (He is spared from Koboi's revenge as the LEP didn't advertise his involvement in her defeat to save face). He delivers the disc Artemis gave him to Butler, Artemis' bodyguard, restoring Butler's memory and allowing the two of them to come up with a plan to rescue Artemis and Holly Short from Opal Koboi, in the Eleven Wonders Exhibition in the Lower Elements which was full of trolls in literally the last minutes. Mulch joins forces with Holly Short, Artemis Fowl, and Domovoi Butler. Mulch sneaks aboard Opal's vehicle and moves the shaped charges to the "booty box." He also steals all of Koboi's precious truffles along with one of her diamond earrings. In the end, he forms PI (Private Investigator) service with former Captain, now civilian Holly Short.
