Well, a quick HP story, and I don't think I can capture his way of speaking, so lay off Hagrid
Flashback during first chapter
"You know I'v 'ever he'rd of 'ther worlds" Hagird said in his thick accents.
"Well, you'd be surprised how many there are; the Great Forest, home to talking cats, Alegesia, home to the legendary dragon riders, Cybertron, home of the giant robots called Transformers...."
"Well, I'm not liken' them 'bots you mentioned" Hagrid laughed "But 'appy a lad i"d be to see one of them ridin' dragons!"
"To bad you won't be able to" a group of voices said. Turning, Thomas saw he was surrounded by a group of suited wizards, with the look and appearance of secret agents!
"The talk and knowledge of other worlds was banned by the International Statute of Wizarding Secrecy, sub act 13. Your know to be taken in for questioning, off world being, and your giant friend will be sent to Akzaban!" they all took out wands.
"Petrific totalicis" they fired a blast of magic at Thomas. He sighed, and flicked his hand. A portal of light appeared and took the magic, and paralized the attacking wizard.
"Pet..." they were knocked back by the force. Before they could get out, Thomas and Hagrid were running like the dickens.
"You don' think they're 'tat mad, do ya?" Hagrid huffed.
"I don't know, but if we don't hurry, my friends are going to be Valdi food!"
"Hey, will' de' put me in Azkaban?"
"I don't think so, they got hit pretty hard"
End Flashback
"If your trying to make a good impression on them, I don't think that worked" Rattrap laughed.
"You do realize, that if they caught me, I could be locked in that prison, shiver" Thomas shivered.
"You may as well try to get that act down from power, else its going to be a problem if Val" Optimus primal covered his lips.
"If mr. Skull face gets out again" Rattrap finished.
"Good point, I should assemble a task force" Rattrap decreed. "It's time to give them kindness, talking, and force!"
"No, no task force. That sound's too much like invasion, I think a more subtle approach is in order. I think we should send myself, and four others, to negotiate, at least make an effort"
"Yeah, that's the smart way" Optimus nodded.
"Oh come on, can't we just blow up something!"
"RATTRAP!"
"Okay, okay, we won't"
"I think you should try and bring people who most fit into the world of wizards, like Seras for instance. A vampire would not be hard to take in living on other worlds" Optimus brought up.
"Yeah, that should work. I believe Eragon would work too, now that leaves two more. Jayfeather, yeah maybe that would work"
"That leaves one more, I say you get Alex russo!" Rattrap decreed. Thomas and Optimus looked at him in shock.
"Alex, on a diplomatic mission! Rattrap, are you on my side!"
"Yep, else I would just say Va...!" Optimus swatted him.
"OW!"
Later
"Okay, I've gathered you all here, for a diplomatic..." Thomas began.
"I'm leaving" Alex turned around.
"Alex, please" Thomas sighed. "we need 5 people who will somewhat fit their normal, to increase our chances of success. Eragon can get Saphira if all else fails"
"Oh, okay" Alex rolled her eyes. "Plus, I think we may see some dragon gut slashing, it will be fun!"
Laugh track
"Would you stop doing that" Jayfeather said telepatchicaly.
"What?"
"That laughing thing!"
"What laughing thing?"
Laugh track
"Oh, never mind!" (Its a joke on the cartoon she comes from, Jayfeather is the only one hearing it!)
In Harry's london
Appearing in a back alley, Thomas and the group snuck around to the muggle streets, listening to the cars roll by.
"Okay, Seras you can whistle a taxi right?" he said as Eragon combed his hair to hide his ears. Jayfeather jumped and landed in the backpack Eragon had donned to blend him in.
"You could have just warped into Dalgon alley" Alex sighed.
"Yes, and get swarmed by wizard agents, petrified and locked in a cage, yeah that sounds fun" Thomas said sarcasticly.
"Not bad wit" she admitted as Seras blew a whistle. A taxi came on in a short bit.
"To this address" Seras showed the cab driver.
"Uh miss, that's a run down building"
"PLEASE" she pleaded cutely. The cab driver blushed.
"Okay, miss. Get on" as they got in, Alex said to Seras.
"Teach me how to do that, please"
Later
As they walked into the leaky caldron, they noticed it seemed empty.
"Uh, doesn't this place have customers, at all" Alex asked rudely.
"Normally, yes, but not today" a agent said, leaning against the wall. A dozen more appeared from the shadows, surrounding the group of five completly.
"The minster, Cornelius Fudge, wishes to see you"
"Good, he sells brownies, right?" Alex joked. The wizards didn't get the joke, and teleported them.
"Hey, that tickle" Jayfeather laughed to himself.
A teleporting later
The group appeared in a office, dizzy from the teleporting.
"Okay, I prefer light portals, so much" Thomas had to say.
"Ah, if it isn't the aliens" a short, old said from the table.
"Hey, your the fudge guy, got any fudge for us" Alex laughed again. "Oh, I'm so funny"
"Quiet!" he slammed his hand to the table.
"Now, excuse her. I brought her with us, not for her manners, or her wit, but for another reason. I am Thomas Greenlight, leader of the world of Greenia"
"Fudge, British Ministery of Magic leader" he didn't offer to shake hands.
"Now, this is Seras Victoria, a vampire from the world of Draculania" Seras smiled, and bowed.
"This is Eragon, a half human, half elf dragon rider, hailing from the world of Alegesia"
"Atra du evarÃnya ono varda, Fudge-vodhr" Eragon greeted in the ancient langauge. Fudge just looked at him funny.
"I am Jayfeather, the cat key wielder" Jayfeather said telepathicaly. "My world is the Great forest"
"And I'm Alex Russo, as you've already world. My world is called Waverly Place, and like you, I am a wizard" she took out her wand and held it up.
"Is that a stick"
"Hey, watch it!"
"Alex, please" Thomas tried to calm her down.
"Fudge, calm yourself as well" a ancient voice said. In a poof, a severe old man with a long silver beard appeared.
"Albus Dumbledore" Fudge said smoothly. "You should go, I can expel these foreigners myself."
"I heard that off worlders were here, and I wanted to see them for myself" he adjusted his moon spectacles, as he examined them.
"Buzz off loon!"
"Sorry, Ms Russo" he didn't turn to look at her, but instead examined Jayfeather.
"Remarkable, this cat shows above Kneezle intelligence. And this boy, is like a mini Hagrid in strength"
"Stop examining me, two leg!"
"Oh, sorry little kitty"
HISSS
"Okay, I'm backing up" he said calmly.
"You know, I think we should here them out" Albus smiled.
"I don't trust them"
"Just here us out" Thomas said calmy. "As you seem to be aware, there exist many worlds. Each of us represents one world, that at one point existed. Now, I know that this world's keyhole was locked long ago, by Colton Wildgrass, an old friend of mine..."
"You knew that traitor!" Fudge stamped. (Note, since 13V is no longer canon, his fate has changed). Thomas was taken aback.
"I remember him, he was a Griffindor, got okay marks, then he vanished, I guess you know the story" Dumbledore pointed out to Thomas.
"THEN, this is where that off world freak is ignorant!" Fudge declared "His friend came back, and was found guilty of breaking the no cross world contact degree to a unbelievable extent!"
"Hey, you never made that law known!" Jayfeather meowed. Fudge was taken aback by Jayfeather knowing that "So how is it fair to punish some one like that!"
"Its corrupt!" Eragon stated.
"It's just pathetic" Seras shook her head.
"Your lame" Alex commented.
"Silence, off worlders have no reason to leave their worlds in the first place!" Fudge growled "World trans contact will lead to chaos unlike any before, even more than he who must not be named ever could cook up."
"Contact has existed between Greenia and several worlds for over 10 years, and nothing from that has set a plauge or such" Thomas told him. "And you just lock up people like Colton for..."
"Oh, I didn't have him locked up, I had another solution, a kiss, by a dementor!"
"A what?" Alex asked
"You took Colton's soul from him, leaving him in a coma forever!" Albus yelled. Thomas had his mouth open, and tears were in his eyes.
"Is it just me, or does it look like Thomas is about to cry" Eragon said telepathicly to Jayfeather. Jayfeather just was stunned. Alex was surprised, and Seras was stealing, and had Fudge held up by his collar.
"What was that for! Maybe its because you took out a qualified hero, that your friend, Mr. Riddle, is such a problem"
"Was"
"I don' think so" Seras tossed him into his chair. Thomas shook his head.
"I wanted to be reasonable, maybe make a aggreement, but after that..." Thomas stopped talking in grief.
"Bannanna Handanda!" Alex yelled, as Fudge's hands turned into two Bannanas, as Seras opened a light portal. They all steamed out.
"Your going to regret what you said" Seras gave one more glare as she left.
"Good riddance" Fudge huffed.
"That was a tad bit harsh" Albus shook his head. "I agree with her, what this day has done will have horrible consequences" Albus vanished. Fudge tried to change his hands back, but it kept failing.
