The Mick

The Mick is a mysterious entity which appears to be the primary antagonist in the plot of Twilight Heroes, who is first mentioned during the quest Protests Aren't for Amateurs. Although it is unknown if the Mick is an individual or an organisation (as suggested upon completion of the said quest), evidence found by a superhero in the Byzantine Interior of the Unborn Base hints that the Mick is indeed an individual.

History and appearance in Twilight

Upon taking Rage to Twilight PD, Rand tells the player,

"We're not sure, but that's our best guess. This isn't the first time we've heard of him, and it usually comes up in relation to some of the crime syndicate activities. He might have been connected--remotely--to the John Steele guy you put away. Anyway, the kid that calls himself Rage says he never met The Mick, though. One of The Mick's hirelings actually recruited him."

Doing this immediately unlocks the hitherto uncompleted quest Cat and Mick-y Mouse Game. The Mick is then subsequently implicated in the theft of goods from ships at night in Go Fish and is revealed in Go Fish, Again to have connections to the Unborn Army.

It is possible that the Mick may somehow be connected to or actually turn out to be Michael Ace himself. This appears to be plausible, given that "Mick" is a slang word-or even a pet name-derived from the name "Michael", and Michael Ace was connected to shady dealings and encounters during C.H.I.P.S. (Casino Heroes Investigate Purported Scandal), Don't Cry for Me, Zion-tina and Through the Dimensional Rabbit-Hole.

Trivia

Despite being a possible combat encounter or chracter in the future, the Mick is not present in the game as an NPC for obvious reasons.
