Intoduction
Wiz: We’ve got two supervillains here. One is the King of Koopas and the other is a merciless warlord from Earth -12!

Boomstick: Yeah, and I haven’t seen a Dark Knight battle yet!

Wiz: Bowser, Mario’s archenemy and self-proclaimed King of Awesome.

Boomstick: And the Merciless, the combination of Ares and Batman! I’m Boomstick and he’s Wiz.

Wiz: And it’s our job to analyze their weapons, armor, and skills... to see who would win in a DEATH BATTLE.

Bowser roars in!
History will be written soon.

The Merciless wages with death!
'''Boomstick: Oh look! It's Ares with a Wonder Woman Logo!'''

Wiz: You're partially right. It's actually Bruce Wayne wearing Ares' Helmet, but he does bear similarities to the God of War.

'''Boomstick: Then why does he have this God Killer sword? Wasn't it from Slade?'''

Wiz: It is so, but a different version of it. His history dates back to Earth -12, one of the worlds in the Dark Multiverse that was destined to die. Here, he presumably grows up in his world's Gotham City and eventually takes up the title as Batman through unknown means.

'''Boomstick: And that's when later on, he finds out that Ares constructed a helmet that would amplify his powers a hundred fold. Basically, if you get hit by somebody wearing it... you can kiss yourself goodbye, if you had time to.'''

Wiz: Batman, along with his world's Wonder Woman, teamed up to try to remove the God of War's helmet and defeat him. A two year war ended up ensuing, with Batman and Wonder Woman falling in love with each other during this time.

'''Boomstick: However, Wonder Woman makes a BLUNDER by getting hit with one of Ares' attacks. Which drives Batman completely nuts. This leads to Batman believing Wondy was actually dead. So he ended up taking the helmet, putting it on, and ended up killing Ares. Wait, Wiz, if there was a Wonder Woman here, wasn't there an army of soldiers and a Justice League?'''

Wiz: Actually, yes. There was an Earth -12 Justice League and Earth -12 Amazons. By the time Batman witnessed Wonder Woman getting stunned, the Amazons and Ares' forces all perished in battle. To follow up, after Batman kills Ares with the helmet, he also kills Wonder Woman, since he found out that she was merely stunned, but not killed. There, he ends up killing various criminals and later heroes in his world until his Earth began to collapse.
