What would be the one thing that would make the Joker even more terrible? Why, giving him supernatural abilities of course. That's exactly what happens in Dark Horse and DC Comics' crossover miniseries where The Joker get his hands on none other than The Mask. Joker becomes gets near unlimited power in Joker/Mask, which spells bad news for Batman and the city of Gotham. The worst part? Joker's already insane!

Joker/Mask begins with Joker and his girlfriend Harley Quinn breaking into the Gotham Museum in order to destroy a variety of sad clown masks, which Joker sees as offensive (much better to blow them up for a good laugh). However, the pair come across The Mask itself. After seeing the powers it grants to one of his thugs who ignorantly puts it on, Joker kills the thug, trying on The Mask for himself. He then transforms into Bighead, complete with the yellow suit and green skin. When Batman enters the scene, Joker/Bighead begins to discover all of the supernatural abilities at his disposal, allowing him to easily beat Batman and run his Batmobile off a bridge and into the cold waters below. While Batman survives and is brought back to the Batcave, he is stuck in a coma. With unlimited power and a whole city for the taking with no protector, Joker/Bighead decides to have the time of his life, which means absolute chaos for the city of Gotham.

The GCPD have no way to stop Joker/Bighead, sending in SWAT teams and tanks which do nothing to stop him. Lt. Kellaway from Edge City tries to help them, though his advice is to just try and keep him contained. Joker/Bighead ends up taking over the news stations, creating his own TV show of terror, complete with awful game show parodies with trivia about his own crimes and killing the contestants if they get the answers wrong. He even replaces Harley with two new side pieces. While the eventual consequence of The Mask is that it makes its wearer insane over time, it doesn't matter for Joker as he's already insane to begin with. Unfortunately, this appears to seem like nothing can stop him.

Thankfully, Batman recovers from his injuries and takes the fight to Joker/Bighead. Because the only way to remove The Mask from someone is for that individual to take off The Mask willingly, Batman has to get creative. He pretends to not know that he's facing Joker, just Bighead. He calls him a pretender and a knock-off, and that at least Joker had original ideas and was sometimes funny. With his pride and reputation offended, Joker ends up taking off the Mask himself, which of course allows Batman to get the upper hand and beat him into submission.

With things back to normal and the Joker on his way to Arkham Asylum, all that's left to do is deal with The Mask. Lt. Kellaway takes The Mask back to a cemetery in Edge City. He goes to a grave with an opened casket. The headstone reads as Stanley Ipkiss, and the skeleton in the casket is wearing a yellow suit. Ipkiss was the original Bighead, and Lt. Kellaway leaves The Mask with him, hopefully to never be worn again. All in all, this miniseries makes for a great story of absolute mayhem. Joker is the perfect candidate to spend some time wearing the Mask, as he's just as crazy as anyone would be when wearing The Mask. However, one might think that while his power would (and does) increase, his personality would stay the same as its already so close to Bighead's already.

Instead, writers Henry Gilroy and Ronnie Del Carmen do something really ingenious which is to create a gradual distinction over the course of the series between their personalities, which Batman is able to take advantage of. Joker's too prideful about his rep, thinking his criminal acts serve as a high form of comedy, while Bighead's antics are more chaotic and random.  The Joker/Mask crossover is incredibly entertaining not just for the characters's similarities but for their differences as well.
