This is set in about the first year of the five year gap, but there is no one apart from the original team and Wolf, although Zatanna is mentioned.

(The others will be coming in soon I promise)

This chapter - Halloween trouble. Klarion casts a spell that...Well I will let you find out. I will say no more.

Hope you enjoy.

Robyn

"Well that was. . . interesting." Artemis announced as she collapsed onto one of the sofas in the lounge soaking wet, in the half destroyed, multi-coloured Mountain.

The rest of the team plus Wolf were lying all around the lounge room. Aqualad was groaning having only just woke up, Robin and Kid Flash had double Cheshire grins, Wolf was sitting between Robin and Superboy, and Miss Martian and Superboy were sitting next to each other covered in paint.

All their costumes were destroyed.

"Let's agree next time we see Klarion that we punch him extra hard, this was so not whelming." Robin decided, but he was still smiling.

An anonymous groan from the team voiced their agreement.

Earlier that afternoon

"Hey guys! Asterous costumes." Robin cackled as he and Wally walked out of the zeta-tubes into the Mountain.

The two troublemakers were wearing nearly matching costumes. They both had a baggy orange t-shirt saying 'Camp Half-Blood' around a Pegasus, blue shorts and red trainers with white wings coming out of both sides. Both of them had a necklace with different coloured beads with weird designs on them. Completing the look; they had bright, mischievous blue eyes and curly, short brown hair. The shorter boy, presumably Robin, was skinny and slightly elfish. The other boy was slightly taller, most likely Wally, and he also has elfish features.

"Woah. Who are you guys supposed to be? And how on earth do you look like that?" Artemis questioned slightly impressed (not that she would admit it).

She was also dressed up. She had a black braided wig and grey eye contacts. She wore old worn out hunting boots, a long black hooded jacket that fell down to her thighs, tawny trousers, a sturdy brown belt and light green shirt. A Mocking Jay pin was attached to her hoody, a plain wooden bow sat in a black quiver alongside arrows.

"Wow. Katniss costume, really Artemis, it's fitting I guess. For your information we are Conner and Travis Stoll, the prankster sons of Hermes from the Percy Jackson and the Olympians series. Robin is Conner and I am Travis. Zatanna gave us a charm that let's us look like them more." Kid Flash stated proudly.

"Wow! You guys look amazing!" Miss Martian exclaimed as she entered the room with Superboy following.

Miss Martian had changed her appearance. She stood taller than normal, but had kept her fiery red hair, freckles and green eyes. She wore a short blue skirt, black leggings and a grey striped shirt. On closer inspection her fingernails were painted red.

Superboy stood next to her dressed up in red checked shirt, a black jacket over the top. He had matching brown shoes and jeans and even his hair had been dyed brown.

"Miss Martian is correct, all of you look amazing." Aqualad stated as he entered the room. It only took a second for him to figure out who the couple were dressed as (it helped that Miss Martian had been talking about it for several days) - Amy Pond and Rory Williams from Doctor Who. It was a British show that M'gann had found one day and loved, she had even convinced Superboy to watch it with her.

Kaldur had combed his hair to the side and wore a black robe lined with green on the inside, a snake with the words Slytherin stitched on one side. He wore a white shirt and green and silver tie underneath the cloak and held a wand (stick) in his hand. He was Draco Malfoy from one of his favourite surface book series Harry Potter.

"Thanks, we were going to be these amazing acrobats that I heard about. You know the Flying Graysons? But we decided against it, it was so sad what happened to them and the poor little boy having to witness it? Just horrible. Hey Robin, didn't you help bring their killer into justice when you were first starting out?" Miss Martian asked.

"Yeah I did. You are right, it was terrible what happened to the family." Robin answered trying not to let his true feelings affect his voice and trying to ignore Kid Flash's eyes on him. He was very glad that M'gann had decided to dress up as someone else.

Wolf padded into the room with dirty black fur and a black mask and cape. He trotted towards Robin who cackled at everyone's confused looks, he rubbed Wolf's head as the wolf sat next to him.

"Robin. What is Wolf dressed up as?" Aqualad asked with as sigh at the youngest.

"He's the Bat Hound!" Robin grinned, Zatanna's charm making him look even more mischievous than ever.

"Wait, who? There's a Bat Hound?" Artemis/Katniss questioned. "How many of you are there?"

Robin cackled then disappeared into the shadows.

"Crazy Bats!"

A few hours later and it was a perfect time to go out trick or treating. The whole team was ready and Superboy had even reluctantly put a collar and lead on Wolf. However, just as they were ready to leave the cave was plummeted into darkness as all the lights went out. The team was immediately alert, looking around for any threat.

"Emmm, anybody else creeped out by the fact the lights just went off and it's Halloween?" Kid Flash asked nervously.

A cackle echoed around the room. The team glanced to where Robin had been previously only to find him still there looking just as confused as the others.

"Robin, please tell me that was you." Artemis begged.

"For once it wasn't." Robin replied his hand already reaching for his utility belt, he always kept it on him at the cave, even if he was dressed up like he was today. Before he could bring anything out a red light exploded in front of the team, temporarily blinding them. Once they could see again they were greeted with the sight of Klarion petting his cat Teekl.

"Hello, Justice Brats. I was bored and it's Halloween so I decided to play trick or treat with you brats. Aren't you lucky? But you don't get the choice of what you want, I do. Seeing as you keep interfering with my brilliant and chaotic plans, I choose...Trick!"

"What do you mean?" Aqualad asked trying to buy his friends time. They were creeping around trying to circle Klarion, cursing how under prepared they were.

Aqualad's distraction was all Robin needed, a Bat-a-rang flew out towards Klarion. Unfortunately Klarion saw it coming and knocked it away with very little effort.

"Uh, uh, uh Bird Brat. No more toys for you!" Klarion laughed before he started chanting a spell.

The team rushed forward in sync in an attempt to stop him but they were too late. Another bright red light flashed around the cave blinding them once again and making them black out. As soon as they were unconscious on the floor, Klarion gave one last laugh and disappeared again.

Twenty minutes later, the first person woke up and rolled off the floor. It was Conner Stoll, not Robin anymore no, Conner. His older brother Travis, who before was Kid Flash, followed fairly quickly. The prankster brothers looked around the room and upon seeing the strange people and alien surroundings they shared a glance before deciding to get out of there. The Bat Hound stretched upon waking and moved out of the room.

Katniss Everdeen, formerly known as Artemis, awoke with a gasp before grabbing her bow and retreating to search out the new area.

Any Pond and Rory Williams, previously known as Miss Martian and Superboy, sat up with a sigh, wondering where the Doctor had dropped them this time.

Draco Malfoy, formerly Aqualad, was last to wake up. He first checked he still had his wand and tried to figure out where he was, moving away from where he woke up he went to find a way to return to Hogwarts.

Klarion's 'trick' spell had made them believe that they were the character they had dressed up as.

About an hour later was the first time any of them met each other. The groups had all been moving around the cave trying to find a way out (with no success). Katniss had an unfortunate encounter with the Stoll brothers. She had crept into the lounge with her bow at the ready, but was still surprised when Travis and Conner dropped down from the roof throwing water balloons. Needless to say she tried to kill them with arrows. Key word being tried, she failed as the boys kept dodging and hitting her with more balloons leaving her completely soaked and furious.

The second time anyone encountered someone else was when Amy and Rory went looking for the Doctor only to find, yet again the mischievous Stoll brothers. This time though they got covered in sparkly multi-coloured paint and glitter. The two adults ended up chasing the brothers around the Mountain trying to stop what they thought were aliens.

The third time involved Draco Malfoy and the Bat Hound. Malfoy kept his nose high as he encountered the dirty beast and the so called beast did the same, completely ignoring the strange boy in his search for Batman and Robin.

It was not the last time that a group met up but none of them worked out well. All involved pranks, several included failed spells, an attempt at wielding a sword, a flying (more like falling) dog and many an arrow being shot. It left the cave decorated in multi-coloured paint and lots of glitter and all parties involved spent the night wandering the cave very confused and lost. They had no idea where they were or why and who the other people were in this place was.

Thankfully the spell wore off at sunrise. Everyone was promptly knocked unconscious where they were as the sun rose outside the mountain, this time they all woke up at the same time exactly twenty minutes later. They all woke up with a groan, dazed and confused by the events of the night. They only had vague memories of the whole night and they were very confusing memories.

They managed to find each other, meeting in the hanger, and tried to piece together exactly what happened - sharing notes on the memories they had. They couldn't help but laugh about the events of the night, although they did have a lot of cleaning to do and were dreading when an adult discovered what would happen (there were lots of cameras around the cave - ones they were decidedly not checking). They had moved to the lounge as they talked, collapsing from exhaustion soon after they made it. It was mostly a side affect from the spell or the fact they had been up all night.

"Lets agree to never do that again." Aqualad half pleaded, only just awake.

"Agreed, but where did you two pranksters even get all the equipment to prank us?!" Artemis questioned, still covered in glitter and splattered in paint.

"We were the Stoll brothers you should never doubt our pranking abilities." Robin grinned mysteriously

"Besides what happened isn't what we should be focusing on. We never even got to go Trick or Treating - meaning no sweets! It's the end of the world as we know it!" Kid Flash exclaimed dramatically.

The only answer was a collective group sigh.

Meanwhile at the Watch Tower

"So . . . What are you doing?" Superman asked the rest of the original seven (minus Batman), plus Black Canary, Green Arrow and Aquaman, for the fifth time.

He had found them sitting around the monitors watching one set of cameras very closely and had wondered what they were doing. They had been so focussed on said cameras that they hadn't answered him the first few times he'd asked.

"Watching the Kids. Klarion came and cast a spell that made them think they are whatever costumes they were wearing." Flash finally answered before cheering as a boy with curly hair, who he assumed was Kid Flash dropped a water balloon on a girl with a bow, who he guessed was Artemis.

"Shouldn't you help them them? They could get hurt?" Superman asked not understanding their lack of concern.

"Nah, the mountains under lock down so no one can escape. Only if it gets serious we will interfere, besides it's entertaining. Now shut up and let us watch." Green Arrow replied this time as a dirty brown dog padded into another room with a boy in green.

For once Superman did as he was told and sat down and watched with the rest of them. He was still very confused though on who everyone was and what exactly was happening.

An hour later Batman came in, he'd gotten suspicion when the Watch Tower had been too quiet and he hadn't been able to find any of the missing adults. Batman glared at the group upon discovering them watching the kids. No one had noticed him yet.

"As you seem to like slacking from your duties, you can help the Kids clean up tomorrow. All of you." Batman spoke up making everyone jump turning to meet his glare with guilty looks. Batman left without another word, heading back to the zeta-beam so he could got to the Mountain and collect Robin.
