You still didn't tell me how it works. I honestly'd like to know. An obviously malfunctioning part of his suit🙂. I have no idea how long he's been using this failsafe, but it also wasn't happening against Carnage. You may not think Batman was a goner, but Joker sure did. These are the scenarios I have for what was about to happen
No Joker--Carnage, who had Bats in a grip sends a spike through Bat's face.
Joker there Carnage thinks he's bluffing about the bomb--
Carnage:Yeah whatever b**ch. I know you ain't that crazy.
*Carnage, who had Bats in a grip sends a spike through Bat's face.*
Joker: I've forgotten more about crazy than you'll ever know!
*detonates bomb. Marvel and DC's 2 main icons are now dead, along with Carnage, Joker and anybody else who was in Gotham @ the time.
Joker there Carnage knows for certain he's bluffing about the bomb--
Carnage:Yeah whatever b**ch. I know you ain't that crazy.
*Carnage, who had Bats in a grip sends a spike through Bat's face.*
Joker: Oh My God! I can't believe you did that
*Spidey and Joker stand there in shock as Carnage turns Batman's corpse into a puppet(You don't wanna know how🙁)*
Batpuppet:Neither do I!
Spidey snaps out and sneaks Carnage, breaking his neck before he can put the puppet down and counterattack. He then catches up to Joker(as he did in the book) and splatters his head with one punch.
Spidey:Batman's death was my fault. With great power there must also come great responsibility. My responsibility from this point on is to take out MFers like this so they can't hurt anyone. Look out psychos! I'm not pullin' my punches anymore! The kid gloves are off!
