One Thursday afternoon
~~~~~~~~~~~~~~~~~~
"Hey mom dad I'm going to go and visit Zatanna" You tell your parents as you run threw the dining room. 
"Okay just be back soon and make sure you have your wand and dimensional scissors" Star tells you as she looked threw some documents.
"Okay I will" you tell her as you grabbed your dimensional scissors from the table.
"Oh and tell her we said hi and if you see Doctor Fate ask him if he can come to the palace and discuss the situation about the rouge wizards" Marco told you as he also looked over some papers.
"Okay I will, see you later!" you said as you ran and cut open a portal leading you to a certain spot on earth were you would meet Zatanna.
~~~~~~~~~~~~
At Mount Justice
~~~~~~~~~~~~
Everyone noticed that Zatanna was happier then usual and wondered why.
"Jeez what's got you so happy?" Wally asks her.
"My bestfriend is coming over and I can't wait!" she then conjured up a picture to show everyone.
"This is (Y/N) they have been my best friend since we were little, they sorta do magic like me but differently" she tells everyone.
"What's up with there cheeks?" Artemis asked as she pointed to your cheek marks.
"Oh,it's a family thing" Zatanna tells them.
"Cool but isn't the League supposed to come and train with us today" Connor told her.
A sudden realization hit Zatanna.
"OMG I forgot about!," she then ran off "I gotta find Black Cannery".
~~~~~~~~~~~~~~~
Couple minutes later
~~~~~~~~~~~~~~~
Zatanna looking relieved.
"So what happened?" Megan asked her as she took out a tray off cookies.
"Black Cannery said that (Y/N) could come but they have to spare with one of us" she told everyone.
"That doesn't sound to bad" Kaldur said.
"Oh I'm not nervous for (Y/N) I'm more nervous for you guys" Zatanna walked to the launch pad to meet up with you.
~~~~~~~~~~~~~
Ten minutes later
~~~~~~~~~~~~~
Zatanna saw a portal appear and a certain butterfly stepping out of it.
"(Y/N)!"
"ZATANNA!"
You both ran up to each other and hugged.
"It's been forever!" You said happily.
"We literally saw each other last week" she tells you.
"Yea well it felt like forever" you joked with her.
"Well I'm glad you can but you see something came up" she told you nervously.
"What do you mean?" You asked her.
Zatanna then told you about the League and how they were coming here to train them all but you need to fight someone.
"Okay" you told her plainly.
"Really!, your okay with it?" She asked you.
"Yea I've been needing to practice anyway" you tell her.
"Okay let's go" she grabbed your arm and ran two the training room were the team and Justice League were.
"Finally your here" Robin said.
Kaldur then noticed you besides her.
"You must be (Y/N), I'm Aqualad, it is a pleasure to meet you" he stuck out his hand.
"Nice to meet you Aqualad" you shook his hand eagerly.
"Um, who are you?" Flash asks. 
"Would you like the first name or full version?" You ask.
"Full version" Batman said plainly.
"Well I am (Y/N) Diez Butterfly princess/Prince of Miewni and future ruler" You told them.
"Never heard of Miewni" Connor said looking at you suspiciously.
"Let's just say its not on earth" you tell him.
You then noticed Doctor Fate in the room.
"Hello Fate" you said waving at him.
"Hello (Y/N)" he said.
"Oh that reminds me my parents want you to come to the palace and discuss the problem with the rouge wizards" you tell him.
"I will go as soon as possible" he tells you.
"Okay now that that's over why don't we start training" Black Cannery then moved everyone to the training room.
"The older members will fight the younger ones and we will see how much you have improved" She tell the team.
"What about (Y/N)?" Connor asked.
"They will fight someone at the end" she tells him.
"Okay first up Kid Flash Vs Martian Man Hunter" Black Canary announced.
~~~~~~~~~~~~~~~~~~~~~~~~
3 hours Later because I'm to lazy to write each fight seen
~~~~~~~~~~~~~~~~~~~~~~~~
"Good job Robin" Black Cannery said as Robin and Flash walk off the training ground.
"Okay who wants to fight (Y/N)" She asked as you went to the training ground.
"I shall fight them" Kaldur said stepping forward.
"Okay go ahead" she motioned to the training ground.
"Quick question can I use powers and stuff?" You ask her.
"Sure" she told you as you ran to the spot were you were supposed to stand.
You took out your wand and got into a fighting position.
Kaldur took out his weapon and made two water swords.
The timer started to count down.
"3"
He noticed you had a look of both determination and joy in your eyes.
"2"
You carefully make a plan to take him down.
"1"
Kaldur lunged at you but you dodged his attack and casted spell.
"Rolling Thunder Lightning Blast" you shout aiming at him.
With that he is knocked out of the ring and slides backwards while the heroes are shocked and impressed at what just happened.
"Winner (Y/N)" the computer announced.
"Sweet" you then walked up to Kaldur. You offered him a hand to get up.
"Need a hand" you asked him.
He excepts.
"Anyway that was fun!" You said happily.
"How the heck did you do that?!" Wally asked you.
"Duh my wand" you said as you showed him you wand.
"How exactly does your wand work?" Green arrow asks you.
"Well you see in my family when the first born turns comes 14 they receive the royal wand," you then pulled out a picture of your family when you were a baby "my mother is from miewni but my father is from earth which technically makes me half human" you tell them.
Megan noticed that your wand looks different from your mothers.
"Why does your wand look different?" She asks.
"well whenever someone receives the royal wand it changes there form for each person, no wand is the same" you tell them.
"And what about your cheeks" Green Lantern (Hal) asked.
"Oh well only royalty or someone related to royalty is born with them," you then pointed at your own "mine are symbols of happiness" you tell them happily.
"Any way it's getting late and I need to get back home," you tell them and then look over at Zatanna "we still up for lunch next tomorrow?" You asked her.
"Yep see you then" she said waving at you.
"Okay" you pulled out your dimensional scissors and cut open a portal.
"Oh and Aqualad no hard feelings" you ask with a little nervousness in your voice.
"No hard feelings" he said while blushing a little.
"Cool, anyway see yea!" you jumped threw the portal.
It then closed while the league and Team just stared were it was.
"Well that was fun" Zatanna said as she walked away to get ready for the lunch you both had planned for tomorrow.
The league and team had exited the training room while Kaldur was at the back looking like a love struck puppy.
Looks like someone has a crush.
~~~~~~~~~~~~~~~~~~~~~~~
Well hope you enjoyed.

This is what Kaldur felt like.
