DC Comics seems to confirm that Batman's most underappreciated villains in Gotham City, in canon, are none other than The Tweedles.
They have a history in DC lore that goes as far back as Batman's classic adventures from the 1940s. Dumfree Tweed and Deever Tweed are introduced initially as nearly identical cousins (not actual twins, as so many people think) who pattern their crimes after classic Lewis Carroll characters Tweedledee and Tweedledum, two Alice in Wonderland characters who they both happen to resemble, coincidentally.
Both in canon and in real life, The Tweedles often go overlooked and oft forgotten in the grand scheme of things, despite having quite the pedigree to their names.
Their comic book history has seen the two serve as henchmen of The Joker (though Joker's weirdest henchperson is still Daffy Duck), members of Lex Luthor's Secret Society of Super-Villains, and had their own gang called The Wonderland Gang.Read more on screenrant.com
