Author's Note: For posterity's sake, I will be adjusting the timeline of the show to coincide with the year 2015, because I can and it makes it easier to list dates. Now, the story takes place about four months after the final episode.

2:00 AM

Jack pulled to a stop at a diner off the road. He stepped out of the car, clicking the lock button on the zotter as he closed the door. He stepped up to the diner's entrance and walked in.

"Good morning, honey." The middle-aged waitress greeted him.

Jack examined her, adjusting his glasses. She was in her 50s for sure, and had red, wavy hair with traces of gray in her roots, which had yet to become brittle. She had brown eyes, and a fair complexion and appearance. She was about 5'7" and rather skinny. All in all, she was rather attractive for her age, Jack thought.

Jack stepped towards the counter and leaned against the counter.

"Hello, beautiful." He smiled, biting his bottom lip.

The waitress blushed as she returned the smile.

"Just for you, then?" She asked.

"Just for me… Joyce." Jack read her nametag. He took a seat at the counter right in front of her.

"What's a nice young man like you doing up so early?" Joyce asked. "Don't you sleep?"

"Not today." Jack said. "I have things to do."

"I see." Joyce took out her pen and put it to the notepad in her hand. "What'll it be then, hon?"

"Hmm… I'll have… a waffle, with a side of bacon and hashbrowns. And a glass of water."

"No coffee?" Joyce asked, scribbling the order down.

"Coffee doesn't agree with me."

"Okay then. Coming up." Joyce tore the ticket off the notepad and brought it to the kitchen.

"As… rning… mut…" Jack adjusted his earpiece as it began to pick up static. "Br… ood."

"What are you going on about?" Jack mumbled to himself. He pressed a button on the earpiece and the signal became stronger.

"Repeat… warning… Mammoth… Lantern District."

"A mammoth? What's wrong with these people?" Jack pushed the button again and the channel went silent.

Jump City

"Warning: Mammoth has been sighted in the Lantern District. All units, proceed with caution. Lethal force is authorized."

"He was bound to show up sooner or later." Cyborg remarked.

"Let's move out, Titans." Robin said.

*Insert main title theme here. One, two, three, four, go!*

Lantern District

Mammoth had already taken care of most of the police force sent to apprehend him. He tossed around the squad cars as they arrived and beat down the officers that managed to get out of their cars. Soon he turned his attention to the rest of the illuminated Chinatown surroundings. His attention was short-lived as Robin's exploding Birdarangs hit him in the back. Mammoth groaned and stumbled as he recovered from the attack. He turned around to see the Titans scouting on a rooftop.

"Anyone ever tell you that going solo was a bad idea?" Robin asked him.

Mammoth growled and roared defiantly at them.

"Guess not." Cyborg said.

"Titans, go!" Robin called as they all leapt to action.

Cyborg immediately fired his sonic cannon at Mammoth as Starfire fired Starbolts. Mammoth raised his arms up to brace against the attacks. Beast Boy changed into an elephant and charged at him. Mammoth placed his hands up and caught Beast Boy by the horn, stopping him in place. Beast Boy quickly transformed into a python and coiled around Mammoth's arm and torso, restricting his movements. Mammoth growled as he struggled, trying to grab at the snake. Raven remotely restrained his arms and hands, forcing them down. Cyborg and Starfire simultaneously charged at Mammoth, punching him in opposite sides of the jaw. Mammoth staggered backwards, trying to keep his balance. Robin drove his Bo staff into the ground and vaulted upwards, delivering a powerful kick straight to his face. Mammoth was sent flying backwards and crashed hard into the ground.

"Don't tell me that's it." Cyborg said, confidently. "I was expecting more, to be honest."

Mammoth stood back up, pulling the snake Beast Boy off of him and tossing him away. He roared at the Titans and slammed his fists into the ground.

"You had to say it, didn't you?" Raven said to Cyborg.

"Come on." Cyborg said. "It's not like we can't handle him. It's one of him, and five of us."

"Knowing the math doesn't give us an advantage."

"If we were all taking a math test, it would." Beast Boy said. "I mean, it's not like this guy knows any math."

"Will you shut up and pay attention?" Cyborg shouted as he fired another round from his sonic cannon at Mammoth.

Mammoth shielded himself from the blast with his arms, charging towards the three of them. Starfire made a beeline for Mammoth to intercept him. The two reeled their fists back as they neared each other, and connected with each other. The force from the punch sent out a minor shockwave that split the ground beneath them. Mammoth winded his other hand back for another blow. Starfire swiftly avoided the attack and punched him directly in the side of the head. Mammoth shrugged off the blow and swung at her again. Starfire grabbed his hand and tossed him towards the others.

Cyborg shouted as he charged at Mammoth and delivered a decisive blow to his back. Mammoth howled in pain as he fell to the ground, trying to grab at the injury site.

Beast Boy transformed into a giant anaconda and once again wrapped himself around Mammoth to restrain him.

"Keep your eyes on him." Robin said as he approached Mammoth.

Mammoth groaned as he tried to get up. Beast Boy tightened his grip on him, keeping him pinned down. Robin pointed his staff at Mammoth's face.

"Don't move." Robin said. "What are you doing here?"

"What does it look like, bird boy?" Mammoth growled.

Robin pressed the edge of the staff under Mammoth's chin.

"I'm only going to ask nicely once more."

"I'm not saying anything to you." Mammoth growled at him.

"You can keep not saying anything in prison." Robin swiftly kneeled down and punched Mammoth in the face, knocking him out cold.

Beast Boy reverted to normal form and let out a loud yawn.

"Please tell me we can go back to bed after we get Tons-of-Fun back to his cell." He said.

"We need to see to it personally that he's locked up." Robin said. "I don't want any surprises. Beast Boy and Starfire, keep an eye out for possible reinforcements. Cyborg, you and I will make sure that Mammoth stays down until the police arrive. Raven, pick up all the officers and tend to their injuries. When they call in for the transport, tell them we're coming along."

"You don't think things are just this simple?" Raven asked.

"No."

"Raven's got a point." Cyborg said. "We dealt with all of our heaviest hitters months ago. You can count who we missed on one hand. Mammoth's just a punk running blind."

"That's why it stands to reason he would join up with whoever's left. We're not going to let things get out of hand."

"Dude, don't you think maybe you're… overthinking things?" Beast Boy asked.

"We can't take any chances. We're not letting our guard down."

"Okay, then…"

The police quickly arrived on the scene to take care of Mammoth. They attached many shackles to his limbs, binding him so tightly that he couldn't move his arms or legs a bit.

"You think these pitiful strings will hold me?" Mammoth taunted them.

"They were made to hold someone much stronger than you." Sergeant Yates responded. "You're not going anywhere we don't want you to."

"Sergeant." Robin said to get his attention.

"We appreciate the help." Yates turned to him. "Don't worry, in an hour, he'll be staring at a newly-reinforced cell."

"We're coming with you."

"Is that necessary?" Yates asked, curiously. "Is there something that we should be concerned about?"

"It's just a precaution. Nothing to worry about."

"Alright, then. If you say so. Once we get this guy loaded up, we can get moving."

The Titans looked on to see the officers struggling to move Mammoth into the back of the transport vehicle. Mammoth, who wasn't making things easy for them, sneered at the scene.

"Let me give you a hand." Cyborg moved past them.

BAM! Cyborg punched Mammoth in face once, before grabbing his arms and tossing him effortlessly into the truck.

"Uh… thank you." One of the officers said.

"No problem." Cyborg replied.

"Alright, let's get this ugly sucker back where he belongs." Yates said. "Let's move it!"

"Let's move out, Titans." Robin said. He, Cyborg and Beast Boy climbed into the T-Car as Raven and Starfire levitated into the air to follow from above.

The police officers moved into their cars and the transport started towards the prison.

"Why do we have to follow them?" Beast Boy complained. "Come on, things are different than before. No one's gonna come to help Elephant-Man."

"There's always someone out there."

"Don't tell me you think Slade is somehow involved." Cyborg said.

"It wouldn't be a stretch." Robin replied.

"I knew it!" Beast Boy shouted. "It's always 'Slade this' and 'Slade that' with you!"

"He's a dangerous person." Robin growled. "Have you forgotten that? He's the only one left capable of causing massive damage."

At that moment, the threes' coms units rang. They opened it to hear Starfire speak.

"I agree with Robin." She said. "We must protect the city against any threat."

"Even the imaginary ones?" Beast Boy asked.

"Yes. Of all of us, Robin is the most skilled at understanding the bad guys. I believe we should trust in his abilities the same way he does."

"Agreed." Cyborg reinforced the sentiment.

Robin smiled confidently with the reassurance.

"Oh, come on!" Beast Boy shouted. "Raven, please tell me that you've got my back on this one?"

"Uhh, I could say that…" Raven said. "But it would be a lie."

Beast Boy growled as he put away his com and crossed his arms.

"Suck it up." Cyborg said. "We're doing this, and it's not gonna be with your attitude. We need to be ready for anything."

Much Further Away…

Jack opened the door to his car and stepped in. He pressed a button on the center console and the monitor turned on.

"Recalculating…" The GPS said. "Course set for Jump City, 84.6 miles away."

"Don't go anywhere." Jack turned the key in the ignition and the engine roared to life. "Here I come."
