Cousins with an uncanny resemblance to each other, Deever and Dumfree Tweed both shared criminal leanings and a fixation on Lewis Carroll's Alice in Wonderland. Teaming up, they've modelled themselves after Tweedledee and Tweedledum from that book, planning often outrageous, absurdist schemes to trap the Batman.
Arkham Origins Incident
It is unknown if the Tweeds had started their criminal career and if they've encountered Batman at least once at this point.
Between Arkham Origins and Assault on Arkham Incident
Around this was when the cousins started there criminal careers.
Assault on Arkham Incident
Tweedledum and Tweedledee were not present in Batman: Assault on Arkham.
Road to Arkham Incident
When Batman brought Joker back to Arkham Asylum, Tweedledum and Tweedledee were playing at the seesaw close to the entrance to island. They escaped the island once Batman drove through the gates, leaving their hats behind in all the hurry.
Arkham Asylum Incident
Though they had escaped Arkham, Riddler had set a riddle involving them. When scanning the seesaw, the riddle "Tweedledum and Tweedledee SAW it. Can you SEE it?" will be solved and their bio can be unlocked.
Between Arkham Asylum and Arkham City Incident
After the shut down of Arkham Asylum, the cousins attempted to leave Gotham but didn't know that they were being monitored by Hugo Strange (and, incidentally, The Riddler), who had the villains transferred to Arkham City when they were apprehended by TYGER at a checkpoint on the edge of the city.
Arkham City Incident
Batman did not encounter either of the Tweedles during this incident.
Before Arkham Knight Incident
After being hired by Penguin to steal the latest incarnation of the Batmobile, their failure led to their incarceration in Gotham City central holding. While there, the Arkham Knight fired three shots with a shotgun, in the holding cells that they and Tweedledie were being held in, one of them explicitly at one of the Tweedle cousins, indicating that all three are dead.

Psychological Profile: The Tweed cousins obession with Alice's Adventures in Wonderland is similar to that of Jervis Tetch but unlike Tetch the Tweeds are not delusional so much as severely dependent on each other with a shared fixation on extreme roleplay. They know they are not Tweedledum and Tweedledee but none the less delight in acting like them. Their complex rhyming and compicated in jokes and prolong their treatment sessions but the intense aggression they show when separated hardly make things easier.
- Obsession with Alice in Wonderland
- Skilled criminal masterminds
- Despite being cousins, could pass as identical twins
