Arslan Altan is the leader of Team ABRN. 

What I want:
She is the serious and mother of the group. Very experienced in fighting.

Relationship with the other members:
She works well with Bolin and they are good friends.
She is like an older sister for Reese, when the later needs help, Arslan helps and advices her.
She is always pointing the mistakes, but cares for Nadir like no one else. (May get shipped with Nadir Shiko)
