The Mad Hatter - Batman: Arkham Unhinged

The nomme-de-guerre of Jervis Tetch, The Mad Hatter was a cruel and sadistic man who thought he was the real life embodiment of Lewis Carroll’s Mad Hatter. Focusing his crimes around hats, tea and Wonderland, he wished nothing more than to find “his Alice.” To do this, he would go about kidnapping blond women he deemed to look like the titular character, killing them when they no longer did what he wanted. 

A frequent enemy of Batman, he would implement many of the principles and theories he learned about as a former neuroscientist, stripping people of their free will and turning them into mindless puppets loyal to him. 

Over the years, he would work with other like minded individuals, forming the rag tag team dubbed The Wonderland Gang. 

Following the closure of Arkham Asylum, The Mad Hatter was transferred to Arkham City.

With only a few mind controlled henchmen and no real power of his own within the prison, The Mad Hatter attempted to capture and break Batman’s mind and spirit, turning the vigilante into his very own Dark Knight. However, this plan ended disastrously, with an irate Batman incapacitating Tetch, before leaving him lying unconscious in his apartment. 

Berating himself for his shift in priorities, Tetch concluded that he needed to redouble his efforts and find Alice, who he believed was somewhere in Arkham City waiting to be found. 

Setting his sights on Vicki Vale, who he had seen talking with Batman earlier that evening, he ordered Tweedledee and Tweedledum to bring the Channel 3 reporter to the Hat Shop, taking up his former haberdashery as his new base of operations. 

While this was going on, he set about procuring his other guests. Kidnapping Pamela Isley, Selina Kyle, Jenna Duffy and GCPD Officer Ruiz, he placed them in a hypnotic daze, dressing them up as notable figures from Alice’s Adventures in Wonderland and Through the Looking Glass. 

With the last of his victims dressed and assembled, much to the displeasure of Vale who called him perverted for changing her clothes while she was unconscious, he set about performing the finishing touches to his plan. 

Springing the trap, The Mad Hatter gassed Batman with a modified version of The Scarecrow’s Fear Toxin, forcing him to endure a horrific nightmare that would push him to his very limits. 

Yet, even with this advantage, he was still no match for the vigilante, who used a sonic batarang to destroy the Hatter’s Master Controller, freeing all his victims from their trance. Terrified and outmatched he fled into Arkham City, first attempting to hide in the sewers and later in the backstreets. Though he was never truly safe, constantly pursued by those seeking revenge against the man who had stolen their free will. 

Jervis Tetch - Batman: Arkham Unhinged

The alter-ego of The Mad Hatter, Jervis Tetch was a talented neuro-scientist and part time haberdasher who, from an early age had a deep-seated obsession with Lewis Carroll’s Alice’s Adventures in Wonderland. 

Believing himself to be the Mad Hatter incarnate, he styled himself after the character, quoting the book on a regular basis. 

He developed an unhealthy desire to find his “Alice,” targeting, stalking and kidnapping young blonde women he found to be attractive; killing them when they no longer lived up to his ideas of who Alice is to him. 

Brainiac-5: Original Timeline - Young Justice: Phantoms

Hailing from the 31st Century, Brainiac-5 was a Coludroid member of the Legion of Super-Heroes. 

Fighting against Dru-Zod's attempt to overthrow the United Planets, he helped defeat this rebellion, returning the Kryptonian general and his loyalists to the Phantom Zone. 

His future was drastically altered when Zod's son, Lor, stole a Time Sphere and travelled back in time to murder Conner Kent, the young hero "Superboy" who inspired the Legion to form and fight injustice in the universe. 

However, this blip in the timeline was corrected with Lor's death and Conner's survival, resetting the timeline with a 99.84  

Brainiac-5: Revised Timeline - Young Justice: Phantoms

A Coludroid member of the Legion of Super-Heroes, Brainiac 5 is a vastly intelligent and hyper-logical being who specilaises with facts and figures. 

He travelled back to the 21st Century in a Time Sphere to return Saturn Girl, Phantom Girl, and Chameleon Boy back to their own time, much to their surprise and delight of his teammates, who'd pretty much resigned themselves to their fate of being stuck in the past and beyond any hope of extraction. 

Dreamer - Young Justice: Phantoms

Hailing from New Genesis, Dreamer is a New God and one of the five Forever People, alongside her long-term lover Bear. 

She was a friend and ally of Conner Kent, having met and worked with one another in 2010 to recover technology stolen from New Genesis. Since then they have stayed in touch. 

When New Genesis was under threat from the rogue Kryptonian Lor-Zod, Dreamer and the Forever People came together to form Infinity Man, teaming up with Kilowog and Metron to stop the time-travelling menace before he could power up the Phantom Zone Projector and free his parents from the Phantom Zone. 

After learning that Zod had targeted another location than the one they were guarding, they all Boom Tubed to the Boiling Lake Crater. Though they were too late, Zod - despite failing to rescue his parents from the Zone before the Projector was destroyed - escaped, killing the Green Lantern Tomar-Re out of spite. 

Months later, Dreamer and Bear accepted an invite to Conner and M'gann's wedding, travelling to Earth to celebrate the prestigious occasion with the couple. 

Garfield Lynns - Batman: Arkham Unhinged

A trusted member of Roman Sionis, aka Black Mask's "False Face Society", Garfield "Gar" Lynns was an arsonist and pyromaniac in charge of burning down the Sionis Steel Mill during the group's first reign of terror. 

However before he could start the blaze, he was knocked unconscious by Batman, foiling Sionis' revenge against his deceased parents and Bruce Wayne. 

Garfield, now going by Firefly, would remain in contact with Black Mask over the next several years, returning to the False Face Society whenever called upon. 

Firefly - Batman: Arkham Unhinged

The alter-ego of Garfield Lynns, Firefly was a notorious criminal and pyromaniac operating in Gotham City. Deriving satisfaction and thrills from lighting fires and watching the destruction unfold, he was well known for his overwhelming desire to see everything burn. 

Before wearing his signature costume in the field, he worked with Black Mask, aka Roman Sionis as an enforcer for The False Face Society, using fire and explosives as his primary weapons in the gang's criminal attacks across Gotham. 

Firefly was a persistent thorn in the side of both Batman and his allies. 

Years later, after escaping from Arkham City, Sionis reached out to his old friend and ally with a proposition; to take revenge against the Warden, Professor Hugo Strange and his Tyger forces that had turned Gotham into a violent police state. Eager for this opportunity, and to also taunt Strange in his failure to catch and imprison him in the Supermax, Firefly targeted places of significance for Strange, keeping the Professor distracted long enough to allow for Roman and The False Face Society to hit Tyger shipments and amass enough supplies to escape Gotham for good. 

Heavily invested in the mission, Firefly failed to make the rendezvous at the Gotham Trainyard, forcing Sionis to leave him behind.
