Gotham City

"So, the Joker took over the nuthouse and dozens of inmates escaped the asylum?" Cisco summed up.

"And earlier tonight, there was one… lad, who was unbelievably and monstrously large and strong. Similar to Bane but much more horrific." Alfred summed up over the comms.

"We need to spread out and find how many inmates escaped from the asylum." The Flash ordered.

"I'll fly up and scour the city." Supergirl said as she flew up, while the Flash, Vibe, Killer Frost and Elongated Man with the Birds of Prey spread across Gotham.

Arkham Asylum

"We need to find the Joker before he unleashes more chaos in Arkham." Batman ordered.

"I think it's a little late for that." Wild Dog grumbled as two inmates attacked him with knives but Wild Dog grabbed one by his arm and knocked him down as Mr. Terrific jumped at another inmate, knocking him down.

More inmates tried to attack but the Canary used her Canary Cry to take them down.

Mr. Terrific engaged two more inmates as one of them threw a punch but Mr. Terrific blocked and grabbed his hand before kicking him in the leg and flipping him over his shoulder.

Henry and Sara were walking down the corridor as Sara spoke up. "Henry… about what happened earlier-"

"What?" Henry turned to her as he noticed the worried look in her eyes.

"You were going to beat that guy to death." Sara pointed out as Henry sighed.

"I told you, Arkham brings back bad memories to me." Henry said. "There are things that happened here that I don't want to talk about." He quickly turned around.

"Oh, why keep it bottled up?" Darhk taunted, as he was in an office, dressed as a doctor. "Didn't Thompkins tell you that you need to let people in?"

Henry growled, ignoring Darhk.

"Coming back here was a mistake." Henry snapped. "The sooner we sort this mess out…"

"…the sooner you flush us out of your mind, is that your plan?" Malcolm finished, dressed as a guard.

Sara held Henry's arm. "Hey." He turned to her with a consoling look in her eyes. "We're gonna figure this out. I promise."

"How are we going to get into the control room?" Arsenal asked.

"Through the vents." Batman suggested as Green Arrow fired an arrow above and pulled down the hatch.

"Courtyard is secure and the guards have taken care of the inmates. Everything else is on lockdown and we'll be able to take control of the asylum soon enough." Spartan said.

"I wonder how the hell did Joker escape the prison on Lian Yu." Green Arrow growled.

"We can ask him when we find him." Batman said as they went through the ducts.

Gotham City

The inmates were attacking a small shop, holding the civilians as hostages before the Flash sped in, taking them down.

In another part of the city, Killer Frost, Vibe and Elongated Man cornered a group of inmates as they tried to attack but Killer Frost froze one of them to immobilize, while Vibe blasted two of them down, while Elongated Man stretched his arms and grabbed two lamps before launching himself at the two remaining inmates like a slingshot, taking them down.

Black Canary, Catwoman, Katana, Batgirl and Huntress were helping the policemen secure the docks as they incapacitated the inmates escaping from Arkham Island on ships.

Arkham Asylum

"Overwatch, how is it going?" Henry called out.

"Well, Team Flash has taken care of most of the inmates that tried to escape Arkham." Felicity said. "How about you?"

"Well, we're trying to take back control of the asylum and what I would like to know is how the hell did the Joker escape the prison on Lian Yu." Sara snapped.

"He didn't." Felicity said.

"What?" Henry and Sara gapped.

"I just checked. Lyla said that the Joker hasn't moved from his cell on the island at all ever since you locked him up two years ago." Felicity said.

"Then how the hell did he take over the asylum?" Henry demanded.

"Maybe there's an impostor, or follower." Snart quipped as Henry ignored him.

"Let's go to the security room and make sure that we've got eyes on the asylum." Henry suggested.

"Hello? Anyone copy?" Someone called out from a radio of a dead guard near them as Henry picked it up.

"This is Henry Fyff."

"Fyff. Yeah, I know who you are. Listen, we've got a problem."

Henry and Sara went through the ducts as they saw under them through a hatch Commissioner Gordon and some policemen as across them was a bald shirtless man, with cut scars across his body, who had a guard strapped to an electric chair on a platform hanging above the floor.

"Let him go, Zsasz!" Gordon ordered.

"Not another step or I will fry him!" Zsasz snarled as there were more inmates assisting him and guarding the room.

"What are we going to do?" Henry whispered.

"I think I can take them." Sara pulled out pairs of knives from her belt.

"Zsasz is dangerous. We're gonna have to catch him off-guard to stop him." Henry ordered. "On three, we get the drop on them. One, two, three."

Henry and Sara descended down from above as they knocked down two of the inmates. Sara kicked the trigger away from Zsasz's hand as Henry tackled one of the inmates to the wall, headbutting him and kicking him in the stomach and throwing down on the floor. But Zsasz lunged at Henry, roaring as they fell over the railing and fell down on another platform that collapsed until they fell onto some power lines.

Sara was facing four inmates, two of them with guns and two of them with knives and pipes as they attacked her but Sara blocked with her sticks before going into offensive. She hit one of them in the knee and kicked. another one in his chest, knocking him down.

The remaining inmates fired from their guns but Sara rolled away, dodging the gunshots and threw a tray at one of them, knocking him out before she flipped over, hitting the inmate in front of her in the head before rushing at the final inmate, grabbing him in chokehold until he passed out.

Henry and Zsasz got up before the former heard more taunts.

"Feels like old times, does it?" Malcolm taunted. "Fighting the inmates to survive, playing hero?"

Henry ignored Malcolm as Zsasz smiled. "The self-righteous Fyff. How sweet. Missed being back in asylum?"

"Not a bit." Henry growled as Zsasz attacked with his knife but Henry dodged and kicked Zsasz back. Zsasz attacked again as Henry blocked with his hands but Zsasz managed to scratch him in his arms as Henry hissed in pain.

"Why are you holding back? End him! He's going to kill you, you know that!" Darhk ordered as Henry ignored him. Zsasz attacked again as Henry blocked with his hands before Zsasz aimed at Henry's legs as Henry hissed before Zsasz knocked Henry back, while a hatch behind him fell down, revealing a now uncovered fuse box as Henry fell down.

"That girl that's with you, I gotta admit, she's got fire." Zsasz smirked. "I think she and I will have a lot of fun."

"Your sister, nephew, Barbara, Oliver, Laurel, Sara, none of them are safe, until you regrow some guts!" Thawne ordered behind Henry, who had enough of the taunts.

"I've been waiting a long time for this." Zsasz growled.

"Wait a little longer." Henry sneered as Zsasz attacked but Henry grabbed his hand, disarming him of his knife and hitting him in the face with his elbow. Henry then roared in rage and started to savagely pummel Zsasz in his face until it was bloodied and threw him towards the fuse box as it sparkled and exploded upon Zsasz hitting it as he screamed in pain, spasming and being engulfed in flames before collapsing to the floor, dead.

"Henry…" Sara whispered from behind him as he turned around and she was looking at him quite shocked and horrified, like if she wasn't even recognizing him anymore before he took a breath and realized what he just did. But then, he felt sharp pain in his hip as he looked down and noticed that he was bleeding until he leaned his back to a wall and slowly fell down in pain. "It's going to be OK." She assured him as he was slowly closing his eyes, while she held his wound.

"She'd never love you… to her… you're just a monster that she wants to redeem… you ended up here once… you end up here again…" Darhk, Thawne, Snart and Malcolm taunted.

Batwoman jumped at two inmates, knocking them down before another one tried to kick her but Batwoman blocked, hitting him in the knee and jumping over him, grabbing him by his neck and throwing him down.

Two more tried to attack her but Batwoman threw a batarang that bounced off one towards another before it flew back towards her before she heard cracking and loud banging and maniacal laugh from the rooftop of Arkham Manor.

"What the hell is that?" Spartan demanded.

"The Joker?" Wild Dog asked sarcastically.

"What the hell has he done now?" The Canary demanded.

"Guys?" Overwatch called out. "You're not going to believe what I found out about Deegan. He was secretly obsessed with the Joker and he was conducting experiments with Venom and…"

Suddenly, Supergirl flew towards the Arkham Manor before a shockwave went off, some debris from rooftop flying down as everyone ran away.

"Move, move, move!" Spartan ordered.

A few minutes earlier

"Batman, we have a problem." Cash told Batman.

"What is it?" Batman asked.

"Deegan took out the guards and was heading towards the manor. He's got a gun." Cash said.

The Green Arrow and Batman cornered Deegan in an office in the ruined Arkham Manor.

"Nowhere to run, Deegan!" Green Arrow growled.

"Where's the Joker?!" Batman demanded.

Deegan smirked. "Always so oblivious, aren't you, Bats? Wherever you go, whatever you do, you never get rid of me." He said with a sadistic tone that both Batman and the Green Arrow have heard before.

"What the…" Green Arrow whispered.

"You think that only because you lock the clown away in a purgatory, it ends there?" Deegan laughed maniacally as his skin was starting to go paler and paler.

"No… that's not possible…" Batman whispered.

"Anything is possible with me, Bats! You should know that!" Deegan said with cracking tone in his voice. "The doctor's obsession with shock therapies, hypnosis, Bane's Venom… a perfect guinea pig for my little experiment. Now, the Joker is reborn!" He pulled out a syringe with a green liquid and injected himself with it before he started to spasm and his muscles were getting bigger and bigger as his clothes were being ripped to shreds due to his growing size.

To explain what happened, well, all I will say is that the next chapter will have a bit of Batman: Arkham Asylum and Batman Beyond: Return of the Joker vibe.
