Marco Belunjay

Marco shares the Jiggle Butt Gang's exaggerated self-confidence, theatrical behavior, and willingness to treat ridiculous criminal schemes with complete seriousness. He readily follows the Leader's plans and participates enthusiastically in the group's signature techniques.

His individual personality receives little development apart from the trio. Like the other two members, his bravado tends to disappear once Fairy Tail's stronger mages begin retaliating.

Marco participates in Secret Jiggle Butt Art, the fighting style shared by the Jiggle Butt Gang. The trio weaponizes pressurized gas released from their posteriors, producing concussive attacks accompanied by an overwhelming odor.

Gas-Butt Triple Ecstasy requires all three thieves to form a triangle and combine their output into a blast powerful enough to damage the interior of a train. Gas-Butt Triple Ecstasy Fire Special ignites the discharge, while Point Blank Ecstasy allows an individual member to use the same principle at extremely close range.

No separate personal magic or conventional weapon is established for the Fairy Tail incarnation.

Marco first appears with the Jiggle Butt Gang when the thieves hijack a freight train carrying gold. Their robbery brings them into contact with Natsu Dragneel, Lucy Heartfilia, Gray Fullbuster, Erza Scarlet, and the rest of their traveling group.

The gang temporarily recruits Wendy Marvell, whom they enthusiastically proclaim their "goddess," before Fairy Tail brings the robbery to an end.

The trio later resurfaces during the search for the Infinity Clock, attempting to steal a component discovered in the Library of Magic. Their scheme again collapses after provoking Erza.

The name Marco Belunjay properly belongs to the corresponding Rave Master character; Fairy Tail's Lackey B is not personally named in the anime.

Wonderful Gocche corresponds to the Jiggle Butt Gang's unnamed Leader and directs Marco and the other lackey.

Karen Berg corresponds to Lackey A, Marco's fellow thief and regular partner.

Wendy Marvell is temporarily recruited into the gang and treated as its goddess.

Natsu Dragneel opposes the gang during its freight-train robbery.

Erza Scarlet later becomes the trio's most dangerous opponent during the Infinity Clock search.
