Bammy is the same species as tammy

bammy crashed on earth directly in kammys home and was kind and sweet to bam but kam has a dark side she’s self obsessed, rude and very aggressive

when bammy takes control of kammy she has full control and they are in sync with the movements

bam and kam are very functional and In sync while tam and sam are very dysfunctional and out of sync

when tam and bam are controlling they’re humans kam is stronger then sam

I can imagine how they met was tam smacking kams ass and getting into a fight

Fun fact kammys hair is naturally spiky and messy she straightens it regularly

bammy is a femboy

they might not even get that might development and just be opposites of Sam and tam like how wario and waluigi are Mario and Luigi’s opposites

they’re basically just the wario to sams and tams mario

the shadow to Sam and tams sonic
Kam is very two faced and the friendly persona she puts on is fake

bam doesn’t have a mouth but can still eat
