"That's right, you better run!" Eli called out as he and the rest of the Shane gang chased some of Blakk's goons away.

"Yes! Run away before you face the wrath of the great Pronto!" the tracker of the gang cried out with Stinky ready to be fired.

"I think they got the message," Trixie commented as she lowered her blaster once the goons were far enough away.

"Hey, where the slug?" Eli asked as he turned back to where he last saw the slug and surprisingly it didn't move from its spot. The slug was black with neon green markings, eyes and antennae. The markings on its stomach was that of a big diamond with three small ones above it and three under it. It's back was outlined with diamonds going down the middle of it's back with small back diamonds in the middle with neon green diamonds in the center of them.

"That's strange, usually they will run to take cover," Kord commented as he put his blaster away.

"That is probably because it's waiting to become part of my arsenal," Pronto stated proudly as he reached for it, but in response, the slug jumped out of reach, "Hey! Get back here you slug!"

"Pronto, cool it," Eli tells him as Kord held Pronto back from going after and scaring away the slug. Eli bent down and started to examine the black and neon green slug, "What kind of slug is it? I don't recall seeing one like this before."

"I don't have a clue man," Kord tells him as he examines the slug as well trying to recall if he saw one before, "Trixie, you have any ideas?"

"Just a sec," Trixie replies as she took out her handheld computer and started looking it up. After what felt like a few hours but were really minutes, Trixie's eyes looked like they were about to pop right out of her head, "I don't believe this!"

"Don't believe what?" Eli asked wondering what could have surprised his friend.

"It's this slug," Trixie answered not even trying to hide how surprised she was.

"Is it some kind of rare slug?" Kord asked.

"Oh please, it can't be that rare," Pronto stated.

"It is actually a very rare slug," Trixie informed him.

"Really?" Pronto asks with the statement catching his attention.

"It says here that it's called an Ecto Spirit," Trixie reads off.

"Ecto Spirit?" Eli repeats a bit confused.

"I don't think I heard of it before," Kord stats after thinking about it.

"I'm not surprised, it says here that it is one of the rarest slugs out there," the camera girl reads off and then bought up more information on it.

"How can it be that rare that even the great Pronto hasn't even heard about it?" the tracker questioned.

"That is because it is rarely seen," Trixie answered and then started to read off the information, "It says here that they will only come out when they sense that their fated slinger has appeared and will wait in certain areas for them. So because of this, it is unknown if they are endangered or not."

"How can they sense something like that?" Kord questioned as he took his turn to try and get the Ecto Spirit, but it just jumped away from him as well.

"It says here that they are connected to the unknown force that grants them that ability along with other unknown things," Trixie reads off, "It also says here that they are very loyal to their slinger and won't let anyone else sling them."

"I never heard of a slug like that before," Eli stats as he watched the Ecto Spirit look around, "Does it says anything about it's power?"

"No, there's nothing else I can find out it," Trixie informed them as she puts her computer away.

Just then the Ecto Spirit perked up and started making it's way over in a random direction in a hurry. But in the same direction not that far away, an object came falling down from the ceiling of the cavern, "Come on, we better hurry over there. That may be someone coming down from the Surface," Eli instructed as he headed over to his Mecha Beast.

"What makes you think that?" Pronto asked as he followed Eli's lead.

"What else do you think it could be?" Eli asked as he jumped onto his ride.

"Good point," Pronto stated as he got onto his Mecha Beast and when everyone was on their transportation, they headed out.

After a very long fall filled with darkness, Danny's eyes were hit with unusual brightness. Once his eyes had adjusted, he saw that he was falling into some kind of cavern with giant mushrooms, grass, and jagged rocks. Danny stared at the area in surprise and shock not expecting something like this to be underground. Once the chair landed on the ground, the restraints that were holding the Halfa in place unlocked letting Danny free. The Halfa jumped out of the chair as soon as he could, glared at it for a bit before looking up at where he fell from, "Thanks for the trip Vlad, but I don't really have time for a relaxing vacation." Without thinking about checking the area around him, he summoned his glowing rings transforming him into his ghostly self and like a rocket flew towards the ceiling.

At the speed he was flying, Danny didn't have time to stop before smashing into a Ghost Shield that appeared out of nowhere. "I was not expecting that," Danny grunted as he floated backward a bit as he rubbed his now sore forehead.

"Sorry Ghost Child, it disappoints me to say this but you will be staying here for now," a familiar voice from the shadows tells him.

"Skulker, I thought you would be happy that you won't be receiving a butt kicking for a bit," the Halfa joked trying to lighten up the situation he was in.

"I would be enjoying it if it wasn't for the fact that I can't hunt you," Skulker informs him as he comes out of the shadow, "Now I have to find a portal that takes me to you." He then lifted up his arm which revealed a hidden gun and pointed it at the Ghost Boy, "Now to make sure you don't escape before the shield is at full power," a powerful blast was shot sending Danny plummeting towards the ground.

Hitting the ground with great strength and speed, a dust cloud was formed where the Halfa landed. Once the cloud lifted, it revealed Danny sitting in the middle of a decent sized crater looking unimpressed. Seeing no need to stay in ghost mode, he reverted back to human. "Great, looks like I'm stuck here until the Ghost Shield runs out of power, find someway back as human or try to find a portal to the Ghost Zone." Just as he was about to get up, a strange colored slug that was black with neon green eyes and markings landed on his knee. Danny stared at it for a bit surprised by it's sudden appearance before saying, "Um, hi..."

"Hi," the slug greeted happily as it jumped onto one of Danny's shoulders without any questions being asked.

Danny justed blinked in surprised unsure if he heard it correctly. Did the slug just talk? "Hey! There it is!" a voice called out.

Danny turned to where he heard the voice and saw a boy, a girl and...was that a mole and a blue troll riding mechanical animals coming towards him? As they got closer, Danny noticed that each one had blue capsules strapped to them and had a strange looking gun. Noticing that they were not that far away, the Halfa started to inwardly panic as questions raced through his mind. Did they see him transform? Why didn't he check to see if anyone was around to see him when he was going to transform?

After a few minutes, the group of strangers stopped by Danny and got off of their robotic transportation. The boy looked at Danny for a moment, then at the chair that rested not that far away, then back at Danny, "I'm guessing you are from the Surface?"

"The Surface?" Danny questioned confused by the question.

"You know the world above us," the girl jumped in.

"Then yeah," Danny confessed not really seeing the point of hiding that fact, "But it wasn't really my choice in the matter to come down here."

"What-"

"Never mind that," the mole creature jumped in interrupting the boy, "Have you by chance seen a black and neon green slug come this way?"

"You mean this guy?" Danny asked as he pointed to the little guy sitting peacefully there that surprisingly no one noticed yet.

"How long has it been there?" Pronto asked surprised, he was sure that he would notice a slug sitting right in front of him. Then with a determined look, he reached out to grab it, "Come here you!" but in response, the slug jumped onto Danny's head to escape the mole's gasp.

Before the mole had another chance to try and capture the strange colored slug, the blue troll pulled him back, "I think we have a bigger problem then getting a slug Pronto."

"What could be more important than getting Pronto a new slug?" the mole now known as Pronto asked confused.

"Like how there is someone from the Burning World down here," the girl stated then turned her attention to Danny, "By the way, didn't you have white hair and wearing some kind of black outfit? Also was FLYING!"

Danny flinched a bit at hearing her say that, he was hoping with all hope that no one saw him. It was just his luck that someone noticed him. He just hoped that he could think of something to get him out of revealing his secret. Noticing Danny flinching for a moment, the boy decided to jump in, "Trixie, I don't think this is the place to be asking those questions," just then an orange slug with a fire like design on it jumped onto one of the boy's shoulders, "It would be safer to talk back at the hideout then out in the open."

"Fine," the girl replied in disappointment, "But I want to know how he was able to fly and change his appearance so fast! He must have a hidden a jetpack somewhere because there is no way someone can fly on their own without some kind of assistance!"

"I'm sure he will explain how he did it later," the boy assured her, then he turned his attention to Danny, "I'm Eli Shane and this is Burpy, Trixie, Kord and Pronto," he introduced pointing to each one in turn.

"I'm Danny Fenton," the Halfa introduced seeing no harm in telling.

"We are going to take you to our hideout if that doesn't seem like a problem," Eli explained.

"Fine with me, I don't really have anything else to do right now,' Danny replied with a shrug as the slug jumped back onto the Halfa's shoulders.

"You can ride with me," Eli tells him as he leads him over to his robotic wolf like transportation.

Danny wasn't very sure way he was following this group to who knows where. He had just met the group, what if they were the bad guys and he didn't know it? But then again, he had to take the chance in following these guys to this hideout. He was in a whole new world that he didn't even know about and this group may just know of a way for him to return home. Hey, they may even know the reason why this unusual colored slug liked to hang out on his shoulder so much. "But why do we have to go somewhere else to talk?"

"Some of Blakk's goons may still be around and I don't want him to get any information he can use against us," Eli answered as he got onto his white and little bit of orange robotic wolf.

"Makes sense," Danny commented completely understanding what Eli meant as he mounted the robot as well, "Who is this Blakk guy?"

"We will explain who he is later," Eli assured him knowing where Danny was coming from, "All you need to know about him right now is that he is not someone to mess around with and not to be trusted."

"But Eli, are you sure we can trust him?" Kord asked in concern as he mounted what looked like a green robot warthog, "Remember Twist?"

"Twist?" Danny repeated a bit confused on not hearing the name before.

"You know him?" Kord asked becoming a bit suspicious of the new arrival.

"No, never heard of him," Danny assures him, "Who is he?"

"Just some jerk that betrayed us," Trixie spat once she mounted her dark blue robotic saber tooth tiger, "We thought he was one of our friends... But in the end, he turned out to be one of Blakk's loonies."

"This Blakk guy doesn't seem much of a nice guy," Danny stated as they took off, "What is he trying to do?"

"He is trying to take over all of SlugTerra," Trixie explains to him.

"SlugTerra?" Danny repeats once again never hearing the name before.

"It's where you are right now," Pronto answered from his robotic mule that looked a bit rusted, "How can you not know where you are when you came down here?"

"One, I never had any plans on going on this trip, I was more forced into it. And two, all I knew was that I was heading to a forgotten land," Danny informs them, "Plus I'm the good guy here. It's my job to stop the bad guys."

"How do we know that you are telling the truth?" Kord questioned.

"Explain the chair I came down on." Danny deadpanned, then he looked at the thing he was riding. "What is this anyways?"

"It's a Mecha Beast, but more specifically the LK-E model," the cave troll answered proudly, "The Mecha Beasts are one of the main transportation around here."

"Cool!" Danny exclaimed excitedly. Sure his parents had built tons of amazing things back home, but this was something else! "Maybe I can get Tucker to help me build something like this once I get back home."

Eli couldn't help but roll his eyes at Danny's excitement. He had a feeling that things were going to become interesting with this Danny's character around.

=====================================

Ok, hey everyone, here is the next chapter of The Phantom of Slugterra! Yes, the Shane gang will also be part of this amazing story! So in this chapter, the slug that will soon be Danny's was revealed. What do you guys think of it's design? I will post it later on my DeviantArt account for you all to see. Then once the chapter is made that shows what the Ecto Spirit's transformation is in, I will post it on it later as well. Now that I have an idea what the slug will be, I will try to work on my other Slugterra and Danny Phantom crossover story idea. As for what this Slug's name will be, you just have to wait for the next chapter to find out. Also, for all of you who had suggested some ideas for this story, I want to say thank you and that I will try and use as many as I can for where I think it will fit. Also, I'm glad that you all have enjoyed this story so far and thanks for all the reviews, favorites and follows.

Until next time, Flare, over and out!
