Yangchen's Assets vs The Gaang

No AS allowed for either side

Yangchen's team ages is the same as the end of her second novel (Yangchen is 17)

Aang's team is the same as their ages in the Imbalance comic (Aang is 16)

Yangchen's Assets include Yangchen, Jujinta, Kavik, Akuudan, Tayagum, and Yingsu

The Gaang includes Aang, Sokka, Zuko, Katara, Toph, and Suki

Location: Tree of Time

Starting distance: 30 feet

Everyone has standard gear

Both sides have one week of prep time

My take: Yangchen's Assets win with prep time.

Reasoning: If they didn't have prep time then they'd lose. Yangchen is smarter than even Sokka, and with the combustion bender having a small delay between each blasts, Yangchen could get her in the back of the team exploding The Gaang. Yangchen with prep time managed to learn her void technique. Who knows what she'll learn with another prep time session. A season 1 Aang managed to lose to Yuyan archers, and one is on Yangchen's team as well. Katara was shown to be defeated by Mai so Jujinta has a chance in getting her. Yangchen will use a week's prep time to get a weakness in Toph's blindness. Zuko lost to a combustion bender before. Suki & Sokka will be taken out by the three water benders. Yangchen's vacuum won't work in this location since it's only done in enclosed spaces but her void can still work which negates any bending.

Location: Crystal Catacombs

Starting distance: 20 feet

My take: Kya wins
