The Beginning of The Clown...

Gotham City:

Arkham Asylum

"Oh... You're Joker? That explains almost everything." - Dr Carry Feather said it after hearing story about Zephyr Breeze becoming Joker.
"Almost?" - Joker asked.
"Yes. I think, I know why I'm here. I want to now why did do that horrible things." - she answered.
"I will make it easy and help you, I stoped taking my medications since they've closed offices." - Joker looked at her.
"Oh, that makes a lot of sence... So what now? Do you want to meet with your friends? I've heard that they're comming today!" - she said it with a smile.
"No, cause I won't be here when they come..." - Joker grinned.
"What do you mean? You're cuffed to the table..." - Joker didn't answered, he started to laugh and then to sing...

That's life, and as funny as it may seem
Some ponies get their kicks
Stompin' on a dream
But I don't let it, let it get me down
'Cause this fine old world it keeps spinnin' around

Gotham City:

Arkham Asylum
Few Hours later...

"You can get in there but be aware that this look is... terible." - Police officer said it to Mane Six that went to crime scene.
"We will be fine, thanks for your help." - Twilight spoked as she and her friends entred the room. It was trult terrible, Dr Carry Feather was lying in blood puddle. A pencil was stuck in her head, propably a murder weapon. On the wall there was a sign: Put On A Happy Face

"Celestia! That was realy Zephyr? My own brother couldn't do such a thing!" - Fluttershy looked away as she saw something written on the wall.
"That's not Zephyr..." - Rainbow Dash spoked.
"What do you mean?" - Pinkie Pie asked.
"It was Joker, Zephyr is dead. We need to find him and make him return our Zephyr!" - Rainbow was clearly crying right in that moment as she was speeking.
"Well, this is going to be hard considering, what he've become." - Applejack said.
"I can help you." - somepony in the dark said it.
"What do you mean? And who you are?" - Rarity asked.
"I'm a millionare. I can help you by giving you money for hunting this monster, and after that finding a cure for him." - he revealed.
"But who are you?" - everypony asked.
"My name is Bruce Wayne."
"Wait, you're son of Thomas and Martha Wayne! Your parents were killed during this whole clown protests!" - Rainbow Dash noticed.
"Yes, and don't worry I won't make it personal, I just want to help." - Bruce said.
"Well, thanks. I hope that we will find him..." - Fluttershy looked again at corpse at the table. "Fast."

Gotham City:

Wayne Manor
Later...

"Master Bruce, I know that you want to help that poor soul, but is that truly necessary?" - Alfred, trusted buttler of Wayne family asked.
"Police won't find him, I need to help them. But without training, I can't do it. I have to go..." - Bruce looked at his friend.
"Don't worry, it's only one year. But, in while I'm gone, be sure that Mr Fox will finished that suit and vehicle in time." - Bruce added.
"Well, ok. I'm still don't get it... Why Bats?" - Alfred asked.
"It was my greatest fear ever since I was a kid. It's time for criminals to share my fear..." - Bruce answered Alfred's question and then left for his journey...

Gotham City:

Ace Chemicals
Meanwhile...

Joker and his thugs entred Ace Chemicals. They've killed everypony in there and then stand in front of a large vat with chemicals.

"Ok, Boss What are we doing here? There's nothing in here we can use..." - one of the thugs asked. Joker only looked at him, smiled and stabed him.
"You see, these chemical are going to help me become something more than just a clown with makeup..." - after a while thug died, and then Joker turned to others.
"Anypony have something to say? No? Good. Thant wait for me here, if I won't get out of there in 5 minutes, wait for me a little bit longer." - Joker without any second thoughts jumped into chemicals.
"You think he's alright?" - one of his thugs asked others.
"Well I hope so. I don't want to get back to penguin and hope for the best." - another one said.
"Look! He's flying back. He's ok guys!" - another thug yelled happy.
"So, how do I look now?" - Joker asked.
"Well, your skin is white, but well your mane is green." - one of them said.
"That's almost like before but at least you don't have to wear makeup anymore... Well besides one thing..." - another spoked.
"What?" - Joker asked.
"Well, your smile. You will have to paint it with something red to make it, or..." - thug hesitated to say it.
"Or what?" - Joker asked curious.
"You can use a knife and cut off smile on your face... Don't get me wrong, that's just a thought." - thug answered.
"Well, that's a good idead. But I think, I will stick to red lipstick or paint. But keep going with those ideas I like them." - Joker smiled.
"Thanks Boss!" - thug said happy.
"What are we waiting for? Move out, unless you want to get cought." - Joker said.
"GCPD! Stop." - a police officer screamed. They've shot a few times in direction of thugs, but they've manage to escape.
"Damn it!" - one of them yelled.
"Don't worry Jim. We will get them next time." - it was Bullock detective and partner of Jim Gordon, a Captain of GCPD.
"I hope so. I've made a promise to Bruce Wayne and I'm planing to keep it." - Gordon said.
"Never giving up huh?" - Bullock looked at his partner.
"You have no idea." - Gordon said.

Gordon was a good Detective and a great Captain, with Bullock they've made a good team. Soon they're going to get some help from a friend. Gotham and with it also whole Equestria will soon change forever, what will happen next? That's a story for another time.

Good night. And always remember... That's Life!
