When there are as many comic book issues as both DC and Marvel have, creators are undoubtedly going to run into some writer's block when trying to come up with new heroes and villains after the more familiar and generic good guys and bad guys.
Villains, especially, seem to take a turn for the weird the more developed a comic brand becomes. From personal vendettas against facial hair to a fascination with kite flying, some DC supervillains are so specific or outlandish that they come off as completely bizarre.
Calendar Man
Every DC supervillain has its gimmick or theme, just like the Hallmark holidays of the year. But, one particular supervillain decided to make his gimmick all of the Hallmark holidays of the year.
Complete with the months of the year tattooed all around his head, Calendar Man is obsessed with all of the different holidays throughout the year and centers his crime around them. Nowadays the character has a darker connotation, but he originated as a joke villain who had separate costumes that corresponded to whatever holiday his shenanigans were themed around.
Kite Man
Kites are a childhood pastime to some people, but for Kite Man, it's his entire identity. Kite Man recently had a renaissance after being a fan favorite side character on Harley Quinn--so much so, that he's now getting his spin-off series.
Kite Man is another DC supervillain that started as a joke to pop culture fans. His name, Charles "Chuck" Brown, is an homage to the famous Peanuts protagonist. He is canonically not the brightest bulb in the pack and his love for kites comes off as endearing instead of threatening.
Captain Cold
Although Leonard Snart had an edgy and cool makeover in the Arrowverse, giving him major main character energy, his origin in the comics is a little stranger. If DC comics fans heard the words "cold" and "villain," they would automatically think of Mr. Freeze, who Captain Cold seems to be a less interesting version of.
After working with his grandfather on an ice truck, Snart escapes his abusive father and starts a life of crime, wearing a visor to supposedly protect his eyes from gunfire. Wanting to defeat the Flash, he sneaks into a cyclotron lab with a weapon and discovers that combined with the cyclotron, his weapon freezes air, thus becoming his entire brand.
The Heckler
The Heckler is one DC villain that is little-known but has big-screen potential, mostly because of his strange nature. Not much is known about his motivation for fighting heroes or his villain personality. Called the "Bugs Bunny of supervillains," The Heckler has no actual superpowers.
Instead, he fights off superheroes with sarcasm and aimed insults, often getting them to effectively defeat themselves, slapstick style. In his off-time, he owns a diner and is the exact opposite of The Heckler. While his villain persona is confident and witty, his real-life identity, Stu, is anal and easily frustrated.
Javelin
Javelin throwing is a commonly known and widely respected Olympic sport--but it doesn't make much sense as a supervillain identity. However, that's exactly what German former Olympian Gunter Braun centered his villain persona around.
A Javelin is a very cumbersome and impractical weapon for a villain to use, especially if they need to hit someone more than once. Although Javelin's javelins were outfitted with some other weaponry, the most effective use of the spear came from Harley Quinn as she stabbed a giant starfish's eyeball with it.
Weasel
Another strange member of The Suicide Squad's Task Force X was Weasel, a human-sized rodent man hybrid. Weasel is almost entirely animalistic with no special powers besides being more durable than the average rodent or man.
Weasel's comic origin is even stranger--and less funny. Jack Monroe was constantly bullied and compared to a weasel by his peers. When he grew up and became a professor, he was convinced that his contemporaries were plotting against him getting tenure, and he dressed up like a weasel and murdered them.
Gorilla Grodd
Possibly serving as the inspiration for the science fiction film Planet Of The Apes, Gorilla Grodd was a telepathic and supergenius gorilla who was bent on taking over the world. After an alien ship crashed into his gorilla colony, the alien aboard gave them all super intelligence and plans for a Gorilla City.
When his plan for world domination is ruined, he is seemingly defeated by The Flash but continues to return again and again, using his telepathic abilities to try to control the minds of others and the world at large.
Ratcatcher 2
What's stranger than a villain who telepathically connects with an army of rats to do their evil deeds? The answer is the second version of the villain who telepathically connects with an army of rats to do their evil deeds.
Weirdly deciding to just tack on a "2" instead of coming up with her name, Ratcatcher 2 is anything but a carbon copy, and she has heaps of main character energy. Banding together with an entire sewer system of rodents may be very bizarre, but Ratcatcher 2 still manages to be one of the most relatable of the Taskforce X members.
Polka-Dot Man
There's nothing particularly scary or villainous about polka dots. They're used as decorations for children's bedrooms and birthday parties regularly. It is, however, strange and unusual to have a supervillain launch energy-infused polka dots at people.
It seems that The Suicide Squad was chock-full of strange anti-heroes. Fans are calling Polka-Dot Man specifically, however, one of the best characters that James Gunn has brought to the DCEU. His timid and odd behavior combined with his flashing polka-dot power makes for a weird but entertaining show.
The Beard Hunter
Quite possibly the most strange character in all of DC is The Beard Hunter. The name itself is bizarre enough, but the supervillain is also characterized by a hatred of all facial hair because of his hormone deficiency and inability to grow one for himself.
An enemy to the Doom Patrol, The Beard Hunter was an obsessed serial murderer who hunted down anyone with facial hair, collecting the beards as trophies of his crimes. He was largely a pushover who lacked confidence and held the delusion that a movie would be made about his efforts as a supervillain.
