So here are the other six characters I have for the story so far.

In the first row we have:

Nebukai (deep-rooted)
Title: ???
Age: 17
Power: Earthbending
Weapons: Hammer
Hair: Light brown (short and is held back by a bandana)
Eyes: Dark brown
Skintone: Dark tan
Height: Medium
Occupation: Mail-delivery-dude-in-training
Previous location: Omashu (before it was sieged)
Nemesis: practically any fire nation solider
Pet: Ostrich horse (named Bo)
Personality: It is possible that he suffers from bi-polar disorder because he is normally a calm and tranquil person but even a simple thing can set him on a rampage. Before Omashu was sieged he really didn't have a problem with the Fire Nation but after he left and within weeks it was overtaken he quickly changed his mind. Now even a mere mention of the Fire Nation can set him off.

's character (almost my complete design)
Hasu (lotus)
Title: ???
Age: 15
Power: Earthbending
Weapons: Small spiked stone clubs
Hair: Auburn (long and held in two high ponytails)
Eyes: Green
Skintone: Average
Height: Average
Occupation: Mail-delivery-dude-in-training
Previous location: Makapu Village (before the gAang visits)
Nemesis:
Pet: Bearded cat (named Kodi)
Personality: For an earthbender she is a very happy-go-lucky girl and often comments on how "romantic" the atmosphere is. She is more than your typical fangirl who follows Nebukai around because she is a very formidable bender but is often distracted by her emotions. She is also more likely to forgive her enemies.
