The young aspiring leader of Ultra team. She's more level headed than most rubies and a bit naive at the tender age of 74. However, her determination and drive shine through in her actions trying to run her rag-tag team of three before the new members were hired. She hails from a large affluent family with many siblings. One hundred and thirty four to be exact. Despite her close-knit, mob of a family, she has developed something of a sisterhood with her elder colleague, Lefty. Lefty always seems to bail Roob out of trouble, but Roob is usually the one who scolds her for being reckless. She has a rivalry with Heliotrope, frustrated by how much stronger Heliotrope seems to be in comparison to her.
