It was never known how they got there. They all just woke up in a strange world with properties very unlike their own. Even though some had died already in their world, they found themselves resurrected in this place. People of the Capitol took notice of their appearance and had Peacekeepers immediately tranquilize them and take them to jail to interrogate them. They tried to get information on why they were there and how did they get there, but to no avail. The only information they could get was on where these outsiders came from.
No one knew anything and the public was becoming anxious, for they themselves didn't have any information on the subject matter. All the Capitol knew is that they're outsiders and aren't welcome. The huge question was how to get rid of these outsiders? Then President Snow suggested the Hunger Games as terms of elimination and the victor can have a comfortable life at the Capitol. Since this was last minute, the President decided that they would use the same arena from the 74th Hunger Games since that one wasn't won correctly and the contestants have no idea of what to expect since they don't even know what the Hunger Games are. Then the new tributes were all whisked away to their personal stylist to get ready for the Tribute Parade as the President released some information on the Capitol's new tributes.
All the tributes came together to get in their carriages for the parade. All but two had bodysuits according to their powers. Sora, Riku, Kairi, Roxas, and Xion had the same outfits. The outfits had thick strings of four that went around the body suits in different directions and eventually went up to the chest and crossed and fanned out at the shoulders. Their outfits were different by the type of metals used to for the strings and the color for the fabric. Sora had gold, Riku had silver, Kairi had platinum, Roxas had copper, and Xion had cobalt. Namine didn't wear a bodysuit. She had a white, floor length robe with a white witch hat.
Xemnas wore his final form organization cloak. Xigbar had a bodysuit with stars and planets on it to represent his power of space. Xaldin had storm clouds shroud his bodysuit which represented his power over wind. Vexen had a body suit covered in ice to represent his power over ice. Lexaeus had his suit covered in rocks and sand to represent his power over earth. Zexion's suit made his body turn invisible but you could see some misty swirls in different colors appear to represent his power over illusion. Saix's suit was covered in moon dust and moon rocks to represent his power over the moon. Axel's suit was on fire to represent his power over fire. Demyx's suit had water flowing on it to represent his power over water. Luxord had suit made of playing cards, chips, and dice to represent his power over time. Marluxia had a suit made out of greenery and roses to represent his power over flowers and plants. Larxene had a suit that glowed yellow and was covered in sparks of electricity to represent her power over electricity.
All eighteen tributes got their own carriages. They all went out as their names were called in this order: Sora, Riku, Kairi, Naminé, Xemnas, Xigbar, Xaldin, Vexen, Lexaeus, Zexion, Saix, Axel, Demyx, Luxord, Marluxia, Larxene, Roxas, and Xion. The crowd cheered as the tributes paraded down the streets. All the carriages stopped in front of the President's mansion as he came out on his balcony to greet the tributes. The national anthem played and when it was over, President Snow greets, "Welcome tributes, to the Hunger Games! I know you young men and women don't even know what that is but you'll all soon find out as you head in the training center. Now let the celebration and preparation of the games begin!"
The crowd cheers madly as all the chariots disappear into the doors of the Training Center.
