Sonic Boom is portrayed as the maternal individual of the Skylanders since she and her cubs are the only Skylanders who fight evil as a family.
As protective as only a mother can be, Sonic Boom Kindergarten shelters under its wings all those who need help.
She also doesn't like bullying. Sonic Boom can also be sentient, as shown in Terrafin Battles the Boom Brothers when she appeared hurt after Terrafin shouted at the griffin in order to get through Sonic Boom's screams.
