a few head canons on Ruby:

Ruby is a predacon but she prefers to be called a catformer

Ruby can retract and extended her claws like a cat. She mostly have them out but when she's with newsparks or sparklings , she has them retracted. Also, She painted them black because why not (they was originally white). Ruby retract her claws when she's nervous or upset. Usually it's a sign that she needs to be calmed down.

Ruby's optics glow brighter than any other bots' and cons' optics since she is part predacon aka catformer. She can see in the dark very well and mostly she wakes up at night to test out her optics and see if she can see in the dark

Ruby has the ability to walk and run on all fours, she often does it to get a bit speed and sometimes, do it to irritate Ratchet. Ruby often use the ability to sneak around, she does have a good sense of smell and will follow her nose to find the scent

Ruby’s claws can tear through metal and they’re very sharp, Ruby usually scratch Icetrack but not too hard that it bleeds but hard enough it leaves a mark.

Anyone else, she scratches them till they bleed. Ruby use her claws to open locks and cut through rope, vines and chains.

Ruby's full legal name is  Rubymist Jasmine Sunshine Troublemaker Gemstone.

Ruby's Decepticon name is Scarlet

Ruby takes huge amount of cat naps, usually sleep in weird places even on bots and cons.
