Doctor Catarantula's Links
Doctor adores his son, and wants the best for him always. He does his upmost to be encouraging and a positive influence to Wolfe, and will even put aside his scientific work for Wolfe's benefit.
Doctor doesn't hate Mothgirl, but he does find her persistence annoying and her dedication to her job short-sighted. Her perceived ignorance is enough that he's unable to stop himself from monologuing when they battle, no matter how many times it turns out to be his downfall.
Doctor considers Feeling an interesting specimen, and is happy to fix them on the regular in exchange for permission to study them and their abilities. That said Doctor doesn't consider Feeling just a scientific curiosity but also a casual friend, and will joke and make conversation with them happily. He's well aware of how dangerous Feeling is, but considers their actions none of his business.
Feeling relies on Doctor to fix them when they tear their body apart, as well as taking care of any other maintenance they require. Conversationally they are short with him but it's mainly because Feeling is not good at holding a conversation; the two of them are on generally friendly terms, to the point that Feeling will weather Doctor's strange sense of humour without complaint.
Dr. Catarantula is fond of Rose, having made her from the DNA of his late wife. He is either unaware that it is strange to make a pet from your dead spouse's cells or doesn't care, as his attitude towards any criticism of the act is flippant. He treats Rose like an affectionate owner might treat any cat, and insists on feeding her a high quality diet.
