Original Description:
 
Barb the Dragon (Spike’s sister)
 
Here’s the oldest of the dragon siblings I revealed recently >>3019900 but in her more adult stage years later. Barb is the mature and responsible adult of all of Smite and Chara’s kids and she keeps her brothers in line when they’re getting a bit too mischievous and always finding ways to help her community so she can prepare for the day when she’ll be the queen of her land.
 
For those wondering, yes, she has the same name as the popular version of Rule 63 Spike in the fandom, but I used it when I was looking up synonyms for “spike” and “barb” was one of the words so I went with it.
