Roob is the brooding and rude muscle of the group. At most times she seems generally grumpy or even aloof at times. She's somehow entirely full of herself but at the same time completely self loathing. As she sees it, she's a complete failure of a Ruby for not being as skilled or talented as her parents or her siblings. She spends most of her days in the town saloon, trying her best to have a grand time with her best friend lefty, the only person she feels she can be herself around, even then, usually she attempts to put on a tough face still. She at her core, is kind of childish. She has hobbies and ambitions but because she doesn't see it as something a warrior would do she puts on a constant rough demeanor to not appear weak.

Additional info:

She has a crush on a Half Gem named Nermling. She's quite shy around him and to not embarrass herself, she tends to avoid him.

Her proper name is Rubletine. A name she can't stand to hear.

She has a passion for cooking and things one could consider nerdy. This aspect she constantly tries to hide.
