Avatar, and The Last Sorcerer [JJKxATLA]

Chapter 1.1 - Soon to be strong

Going with the Avatar might have been a mistake.

Rafa watches Aang jump across the stage during a firebender performance, trying to "save Katara", which was being used as part of the grand show.

Aang saves Katara with his airbending, dispersing the dragon made of pure fire that was coming towards the tied-up girl.

The flames disappear in a ray of colors while the monk loses his mask in the process,

Rafa in sync with Sokka at his side, groans and jumps in the middle of the stage. Aang, being booed by all the various civilians there, starts trying to dance to reverse the situation, a look of shame on his face.

Rafael helps Sokka untie Katara, the knot being very loose is undone, and the boy murmurs to the two.
"Why do I feel like situations like this always happen to you guys?"

A civilian promptly yells the moment he notices who Aang is.
"Hey! That kid's the Avatar!"

Aang freezes comically and retreats closer to the 3 now with Katara already released, they discard their masks to the ground, Rafa making a point of throwing it in the direction of the guy who snitched on them.

Then from the hole made in the paper wall behind them, a man appears,
"You 4! Follow me! I can get you outta here!"

Without even thinking about it, the four of them dash off running through the hole, Fire Nation soldiers quickly trying to catch them by climbing onto the stage.

With the young people passing through the hole in the wall, the man throws a bomb as a distraction to the ground, spreading smoke,

Everyone speeds past the crowds, bumping into several people and knocking over a man's merchandise, who receives a low "sorry" from Rafa.

From all sides, as he entered the alley, the boy could notice soldiers behind him getting closer and closer.

"I'm calling Appa!" Aang blows his whistle, after taking it out of his pocket. Sokka quickly wished that the whistle actually worked.

Making a sharp turn down one of the several alleys, the man guiding them then turns around and comes running back.

"Okay! Not this way!"

After going to the other side, Rafael notices that a group of soldiers are also running from that place, 'Oh god, I hope that giant ball of fluff actually heard the whistle.' The boy thinks, his legs aching slightly, and his heart starting to get worried.

They make another turn, but the way they came is once again blocked by guards.

The mysterious man throws another smoke bomb and runs past them into another alley.

The group comes across another dead end where there is an enormous supply of fireworks,

Rafael can't help but smile, not caring about the dead end, in the sky he can see the great flying bison.

"Appa! Down Here!"

The gigantic bison lands between them and the guards, with his backside facing the opponents.

Appa airbends a gale force wind which results in the guards getting blown out of sight.

Everyone started to climb on top of the animal, and in a few seconds, the animal was already flying away from there.

Rafa doesn't even notice the man there throwing a bomb at the fireworks causing a commotion popping them all.

…

Now flying away in the sky, Rafael finds himself in a mix of apprehension and wonder at how high they are. Sitting in the cell he runs his hand through Appa's fur, a smile on his face.
