Danny followed Bobby through the halls of the Waverider, wondering where he was and how he didn't know his girlfriend's uncle was the Captain of a whole spaceship.

Stepping through a door, Danny figured this was the bridge. There was a row of chairs around a pilot chair in front of a window looking into some glowing green void.

There was some high-tech computer and a lounge in the middle of the lounge. Stepping through a door was a short Hispanic woman in a jean jacket and cargo pants. She looked up, smiling a little when she saw Bobby.

"Bobby," she said, walking over to Bobby and hugging him. "The heck are you doing here? It ain't Friday night."

"Yeah, I know, but I got a family problem," he answered, hugging her back and looking at Danny: "This is Danny. He's dating my niece and fought with a time traveler. Danny, this is Spooner. She's my best pal and current Captain of the Waverider."

"Uh, hi," Danny said.

"Hey Danny," Spooner said. "yeah, I just got the alert that there was a big change to the timeline and was about to get the team in here."

"The rest of the legends have returned on the jump ship, Captain," Gideon said. "Thanks, Gideon. Tell them to come to the bridge for a mission briefing," Spooner grinned.

"I already have Captain," Gideon said. Danny looked. In a couple of minutes, a group of people came in: an African American man, a man with pale skin and bushy red hair, a short, um, Danny wasn't sure what to call it, a furry meatball with feet or a hairy dwarf that wasn't wearing pants.

Anyways, the last one was a twenty-something girl who, for some reason, looked familiar.

"Bobby," the two guys and the hairy person said before coming over and hugging Bobby. "What are you doing here?"

"Family problems," Bobby explained, patting the guy on the shoulder. He looked at Danny. "This is Danny. He's dating my niece. A time traveler picked a fight with him. Danny, this is Bampett Muhammad, Captain Caveman, and Arthur Clawthorne, the Legends of Tomorrow, and this is I don't know," he said, looking at the familiar-looking girl.

"My name is Jo," she said quickly with a weird smile. "I'm new"

Bobby nodded. "ah yeah, welcome to the team, Jo," he said before looking to the dashboard. "lay it on us, Gideon. What needs to be changed?"

"According to Bedrock news reports, Pebbles Flintstone and Bambam Rubble were found deceased in Rock Vegas on the day they were to be married," Gideon said, showing a hologram of two people dressed as Cavemen laying on the ground.

"This couple is very distant ancestors to you, Mr. Fenton," Gideon said. Danny frowned in understanding Freakshow's son had targeted Danny's ancestors because he couldn't get to him, but why did he want to go after him?

"Why go after me?" Danny asked. "I fought his parents, which still grosses me out, and Desiree has been a pain in my neck since I was fourteen, but why travel in time to go after me?"

"Because of the circus of crime," Jo said, walking over to the dashboard she typed in, showing a holographic image. Danny saw Freakshow Kid and a gang of people dressed in circus outfits in handcuffs.

"Ringmaster AKA Frederich Isak Showenhower junior was the ringleader of a gang that had a major crime spree across the United States until he was stopped by Danny Phantom, Ben Tennyson, and Kim Possible," she explained, "When he was arrested, he swore revenge on the entire Fenton Family."

"And he decided to wipe us all out at once," Danny summed up. "terrific, let's go."

Bampett patted Danny on the shoulder. "I like this guy. There's a chance he'll be wiped completely from existence, and he doesn't even flinch," he said with a laugh.

"Thanks, I think."

"Right then, Legends, let's go," Spooner said. "everyone straps in."

Everyone went over to one of the seats. Danny walked over, sitting between Captain Caveman. 'Man, my life is weird if I'm not even questioning that name,' Danny thought, and Jo.

"Brace yourself for the side effects, new guy," Arthur said.

"What side effects."

"You'll see," Spooner said before pulling the lever, "setting course for Bedrock in the Cretaceous era."

The Waverider engines revved before they zipped forward. Everything moved around him in a flash of light. Danny groaned, having a killer headache as the Waverider flew over a city with buildings made of rocks. "Home sweet home," Captain Caveman said with a grin,

"Switching cloaking on," Spooner said before her chair turned. "All right, Pebbles and Bambam are at the Rock Vegas Hotel and Casino. We plan to stop Ringmaster and Desiree from hurting them so they can get to their wedding and save millions of years' worth of their descendants."

"Me included," Danny said, standing up and falling over, landing face-first on the ground. "ow," Danny groaned.

"Yeah, that's one of the side effects," Bobby said, helping Danny up to his feet and back into the chair. "don't worry, Danny boy, the effects are temporary."

Danny nodded, getting feelings back into his legs. "right, take Danny to the fabricator. Go to the Rock Vegas hotel, watch for Ringmaster and Desiree, and stop them. We only have one chance at this,"

Danny walked around the Rock Vegas hotel in a white knee-length pelt with red spots and a blue tie. "I can't believe that people were around during the Cretaceous era," Danny said, amazed as he looked around. Honestly, it didn't look much different than life in the twenty-first century.

Although the lack of shoes was painful

"Yeah, paleontologists don't discover any of this until the twenty-fifties," Arthur said with a stone tankard filled that he took a sip from on the other end of the hall Bampett and Jo were working together. Bobby was running from the Waverider.

Captain Caveman was apparently a local hero, so he kept a low profile with Spooner. Danny noticed from across the room that Jo looked nervously at him.

"So, did I somehow offend Jo? She keeps giving me weird looks and acting nervous around me," Danny asked, hoping the time traveler didn't have a crush on him.

Arthur took a sip of his drink before he answered, "It's a bad idea to know too much about your future." he answered, "Jo is nervous because, in her time, you two are close. It's probably a little weird seeing you younger than her."

Oh, that made sense. If he and Jo knew each other in the future, she must have been nervous about accidentally letting something slip about his future.

"Hey, eyes up, Cavey and I have eyes on the happy couple, no sign of Ringmaster," Spooner said. "what's on your end?"

"No luck, Captain. We haven't seen any sign of Rignmaster or Desiree," Arthur answered.

"People with ghost powers don't set off my ghost sense, and Desiree is sneaky. She won't come out unless she can cause chaos or grant a wish."

Just then, the ground began to rumble, and everyone in the casino turned to see a stampede of triceratops burst into the casino. "I just jinxed us, didn't I?"

"Eh, might just be our luck," Arthur said. "Bampett, Jo, you guys meet up with Spooner. I'll stop the stampede," Arthur said, reaching into his hair and pulling out a staff with an owl at the end. "come on, Archimedes, let's go."

Danny watched as Arthur spun his staff in a circle. A glowing circle followed the staff's path before a giant blue stop sign appeared in the air in front of the triceratops.

The triceratops stopped bumping into each other.

"I," Danny said, blinking in surprise. "I was not expecting that to work."

"Well, of course, we stopped. The scary green lady isn't here," the lead triceratops said, surprising Danny that a dinosaur could talk, though maybe he shouldn't be surprised since cavemen and dinosaurs lived at the same time.

"Wait, scary green lady?" Danny asked the dinosaur, something he never thought he'd do. "where'd you see her?"

The triceratops turned their heads "that way."

"Thanks," Danny said before running off. Hiding behind a pillar, he went ghost-flying off, turning his costume into his caveman outfit but black with white spots.

"Okay, this is new, but I'm not complaining," Danny said, flying invisibly through the air. Flying, he spotted Desiree below the cave. People were scrambling for money, shooting out of all of them.

Danny quickly flew in, kicking Desiree in the face. "hey, Arabian nightmare, this casino has a no ghosts policy," Danny quipped, firing a ghost ray, "or it will because of you."

Desiree dodged the blast before her tail flew out, grabbing Danny by the throat and sending her crashing into a row of slot machines. Danny pulled himself up.

"Wait a second, it's Desiree. Why am I fighting her? She grants every wish she hears," Danny asked himself. "I wish you'd go back to the ghost zone and never grant a wish involving time travel again."

Danny expected Desiree to grant the wish and go away, but nothing happened. This was different from what usually happened.

Desiree smiled before a ghost ray at Danny while pointing to her ears. She was wearing earplugs. "a suggestion from my friend Ringmaster," she said before turning her arm into a sledgehammer and swinging it down at Danny.

Danny swerved and dodged the shot, flying up and rushing at Desiree. If he couldn't do this the easy way, he'd do it the hard way. Danny flew up, dodging a punch from Desiree, firing a ghost ray, hitting her in the stomach, and knocking her into a pillar.

Desiree scowled, her eyes looking down before she grinned, turning and firing a ghost ray at two guys. Danny dove down, blocking the attack before pulling out the Fenton thermos. Aiming, he fired, trapping Desiree inside.

"And stay in there," Danny said, looking back to the two guys, one who looked a lot like his dad and a short blonde guy with blonde hair. "Are you two okay citizens?" he asked with his superhero voice.

The guy who looked like his dad nodded. "Yeah, sure, thanks, kid. Come on, Barn, we gotta find Pebbles and BamBam," he said before grabbing the blonde guy and pulling him along.

Danny tapped the earpiece in his ear. "Guys, I caught Desiree. Any sign of Ringmaster?" he asked.

There was the sound of blasts ringing in his ear. "yeah, we found him, and he's got some backup. We're in the wedding chapel."

'I'm going to stop asking questions about this period,' Danny thought. "I'm on my way," Danny said, flying away.

Making his way into the wedding chapel, Danny saw Spooner and Bampett ducked behind a pew protecting Bambam and Pebbles, trading fire with two guys and a short blonde cave lady shooting at them while Arthur, Captain Caveman, and Jo were flying through the air dodging little tattoos from Ringmaster.

Danny flew at Ringmaster and was about to deck him when flying rocks hit him in the side.

"I don't know what you are, freak," the short blonde lady said, "but we're getting paid to wipe you out with these two lovepterodactyls," she said

"Take out these freaks, boys"

"Yes, ma," the two other cavemen answered, turning their guns towards him before they began to shoot

Danny swerved and dodged before he got hit behind by Ringmaster

"So you've picked up a new gang," Danny asked.

"Well, what's a ringmaster without his troupe," the Ringmaster said, the tattoos on his wrist changing, forming around his wrist, becoming a python that lashed out and attacked Danny.

Danny bent backward, flipping over so he was right side up again, and fired a blast of ice that froze the cavemen's feet to the ground. "Real hazard to not wearing shoes," Danny quipped before seeing Ringmaster inches from him with a tattoo sword aimed at his neck. Danny didn't have the time to dodge.

Before Ringmaster could finish the job, he was hit by a ghost ray, one that Danny didn't fire. Danny looked to see Jo with her hand extended, nodding to him.

Danny nodded back.

Once the fight was over, Spooner used a machine to

erase the memory of the cave people taking the thermos with Desiree trapped in it and Ringmaster in the Waverider, leaving them both in the brig while they headed back to the twenty-first century. Danny hoped the side effects wouldn't be as bad this time around.

"All right, we're back in the twenty-first century Wizville," Spooner said, getting up before landing the Waverider. She said before she got up, Danny thankfully didn't have to deal with any side effects.

"Kcab eb ot doog," Danny said before he blinked. "Gnorw s'gnihtemos"

"Yeah, that's a nasty side effect," Bampett said. "Don't worry; it wears off fast."

"Gniyonna si emit," Danny grumbled before his tongue felt funny. "I mean, time travel is annoying."

"Cavey can relate, Danny Cavey can relate," Captain Caveman said with a nod.

"Well, Danny, it was nice meeting you," Spooner said

"It was fun," Arthur said to Bampett, and Captain Caveman nodded.

Danny nodded. "likewise," he said, looking at the others and Jo, "thanks for saving my life."

Jo shrugged. "no problem," she said with a nod and a smile. Bobby said goodbyes, promising to see everyone on Friday before he and Danny left the Waverider.

"So what's on Fridays," Danny asked.

"Family dinner on the Waverider," Bobby explained he said as they walked towards the Proud house. "well, second family," he said, looking back to the Waverider, waving as the Waverider took off with a grin on his face, watching it disappear as they walked up the driveway.

"Hey Bobby, thanks," Danny said before Bobby could open the door, "for helping me and my entire family."

Bobby turned and shrugged. "Ain't no problem. You would've done the same for me, Danny," he said, nodding.

Danny nodded, walking into the Proud house he said Penny walked over and smiled at him, kissing him on the cheek. "Hey boo," she said, "everything goes alright with the ghost."

"It was good, no problems," Danny said

"Well, great, you're just in time, dinner ready," she said

"Ah yeah, dinner sounds good," Bobby sang. "Let's get our grub on."

Danny smiled, walking arm in arm with his girlfriend into the dining room.

Back on the Waverider, Jo was looking at a picture on her phone, a group picture of the Legends in Rock Vegas with Danny. "excuse me, Miss. Fenton," Jo looked up from her phone, "I've detected a new change to the timeline."

"I'm on my way, Gideon," Jo said, staining up.

"How was it, Miss. Fenton fighting side by side with your father?" Gideon asked. Jo smiled, pocketing her phone. "it was legendary, Gideon, it was legendary."

Wow, I didn't know that Danny would be related to Fred Flintstone!

"Well, he would be more related to BamBam because of the white hair…" Deadpool said

I'm guessing that his white hair was a Dormant gene That he awakened after turning into a ghost.

"Well, PFN has some sad news for you guys about this story. This story is going to end in a few more chapters..." Deadpool said sadly.

Hey, don't worry. We do have Gwen TDI to finish and the Phantom and Ladybug series. Also, there are new stories like Totally Phantom, Phantom Omniverse, and the Ghostly Encounter of the Cure times.

"I know the first three but don't know the last one. What show do you want to crossover that has the name Cure?"

You have to wait and find out next time. Special thanks to Number Boy for helping with this chapter
