When DC fans think of the world's greatest detective, Batman, their minds tend to travel to the Bat's relationships. They almost always think of the orphans and Robins Batman brings in and turns into icons. Usually, they don't think of some of the more out there and bizarre Batman allies.

Granted, a man running around in a bat suit is more than likely to attract plenty of weirdos but Batman's gathered quite a good amount of oddballs. From supernatural heroes, villains who constantly switch between good and evil, and other strange friends, the Bat has made some good yet strange friends.

Jason Todd/Red Hood

In all of Batman's allies, the Robins are the most well-known. While many fans adore each one, most have a bizarre past to them, with Jason Todd having the oddest. Batman's second Robin, Jason increasingly got more violent as his relationship with Batman progressed right up until his brutal death.

Of course, death wasn't the end for Jason as he came back as the anti-hero, Red Hood. Yet, despite his new anti-heroics, he and Batman kept an on-and-off friendship. One second, the pair is at one another's throat. The next, they're sharing dinner on the Batmobile. It makes for a weird friendship but a heartfelt one nonetheless.

Toyman

Now, by comic standards, Toyman is seen as Superman's enemy. Yet, during a run of Superman/Batman, the two heroes encountered another Toyman, a young genius boy named Hiro Okamura.

An incredibly intelligent boy, Hiro ended up helping Batman and Superman by creating a rocket and flying into asteroids. Although Batman's known to recruit young boys to his cause, Hiro always stuck out as one of the odder ones, narrowly balancing the line between good and evil.

Harold Allnut

While Batman's known for being a smart hero with plenty of gadget designs and tech under his belt, even Batman needs help at some point. Besides Hiro and a few others, Batman had another friend he relied on for help, a man named Harold Allnut.

A mute man who was always seen as an outcast, Batman would come to Harold from time to time for assistance on repairs, designs, anything he could get. Over time, Batman and Harold formed a tight bond. A bond that would be exploited by Harold when the villain Hush offered him his voice in order to betray Batman. Since his untimely death, the odd yet loving friendship between Batman and Harold has yet to resurface.

Etrigan The Demon

On his own, Jason Blood is quite the character for one to be friends with. An immortal knight cursed to walk the earth for all eternity, Batman meets Jason as a demonologist. However, he soon meets the other side of Blood: A demon tied to his immortal curse, Etrigan.

Summoned via a rhyme, Etrigan and Blood share a tenuous relationship, quite like the one they share with Batman. Even though the Dark Knight sees plenty of strange allies, Etrigan and Blood fit the description all too well: a demon and his host helping the Knight stop crime. Not to mention Batman was once Etrigan's host for a brief moment.

Deadman

Deadman comes back in his ghostly form

Beyond Etrigan, Batman has other supernatural allies. In the beginning, Boston Brand was a stuntman in a circus. However, when he was killed, he became the ghostly hero Deadman, a spirit who could possess anyone and move about undetected.

At one point during Brand's time as Deadman, he came into contact with Batman. While he would time again try and possess the Detective, there were plenty of times Deadman and Batman would work well together despite one being a ghost and the other a human.

The Outsiders

Any DC fan worth their salt knows all about Batman's strained relationship with the Justice League but some fans always seem to forget the Outsiders, a unique team that Batman put together to fight crime in places the Justice League couldn't.

With core members like Black Lightning, Katana, and Metamorpho, Batman always seemed to lean towards the stranger heroes to get the job done. Still, although the oddness of the relationship this band of misfit heroes persisted as the years wore on, specifically between Batman and Katana.

Clayface

It's apparent Batman's evil rogue's gallery always go through a vicious cycle: go against the Bat, get locked in Arkham, break out, rinse and repeat. Yet there are times when Batman's villains did try to go good; like Clayface, a former actor turned into a shape-shifting monster due to an accident.

During the "Rebirth" run of Detective Comics, Batman recruited Clayface to be a part of a new team. Slowly, Clayface began to work to do good for Gotham and be more of a hero. He even struck up a relationship with an orphan named Cassandra Cain. Unfortunately, though, Clayface ended up losing control over himself and left Batman's group after his supposed death.

Riddler

It can be said that Riddler is one of Batman's more annoying foes (at least, in the Arkham games he is). Constantly sporting a genius IQ and obsession for riddles, Edward Nygma was one of Batman's first enemies that would plague him for years to come. Then, at one point, Edward seemingly turned over a new leaf.

After falling into a coma, Nygma emerged a changed man. He ended up starting his own detective agency that would aid Batman from time to time, creating an odd relationship between the two former rivals. Of course, comics being comics, Edward was eventually back to being the villain he was but for that brief period, he was an actually interesting and non-annoying character.

Catwoman

Catwoman prepares for a heist

Out of all of Batman's rogues, everyone knows of Selina Kyle, Catwoman, and Batman's relationship. A masterclass thief, Catwoman's become one of Batman's many femes Fatales like Talia Al Ghul and has constantly led Batman on chases and multiple romantic endeavors.

Recently even, Catwoman almost married Batman. Instead, she left him at the altar and raced off, only to return to his arms. Although they are now somewhat married and together, no one would be surprised if they separated once more and continued chasing one another across the rooftops as foes rather than friends and lovers.

Bat-Mite

Bite-Mite meets with several Justice League Members

There are plenty of Batman characters who ooze evil and others who exude good. Then there are the likes of Bat-Mite. An imp from the fifth dimension, Bat-Mite has an unhealthy obsession with Batman and uses his powers to cause mischief and mayhem for the Detective.

Over time, Batman would develop an uneasy friendship with Mite, one that it would test every time. Once, the Mite caused the Joker to become an omnipotent being known as Emperor Joker who tortured Batman over and over. Although not intentional, most of Bat-Mite's shenanigans end up that way: unintentional and dangerous to his "friend."
