Sorry I didn't post this earlier, but school was catching up. That being said, the colors are based on what is CURRENTLY going on and not what will go on.
Pacster: The arrow says that Pac likes him (cause he looks and acts cool), but he doesn't like Pac. The reason for this was initially caused by Buttocks at first, he will start to like him later on in Old Friend AU, but for now, he just feels really uncomfortable around him.
Cylindria: She's neutral with Robin, but he merely doesn't like her because he thinks that her reasoning for most of her actions and words can be very questionable. (For example, S1-EP01, the Cyclops incident) Plus he sees her as annoying for now, again it does get better.
Spiral: Not much to say about him, Spiral was the first to meet Robin, and Robin's reasoning for appreciating Spiral than the other two is mainly because he feels more comfortable to be around, plus he's not as flawed as the other two.
Skeebo: OH NO! Seems that at a later date, Robin had fallen in love with this loser! What a tragedy! His reasoning for that affection is mainly just how Skeebo acts and is as a person, behind that regular jock mask. He's an absolute sweetheart but didn't want to show it, however Robin saw it and fell HARD. And it does get reciprocated, at a later date.
The Ghost Gang: They're all trouble makers to him, so he probably didn't want to meet them at this point.
Sir Cumference: LITERALLY LIKE A FUNKY GRANDPA TO HIM. He was skeptical at first, but after getting to know him, he really appreciates just how much he cares and listens to the heroes' needs. Sir C has the same feelings at first, but he now sees him as just a sweet kid probably in need of some assistance.
Fuzzbitz: He adores this little monster and is very grateful to meet him. Despite being a threat technically, the little creature can't seem to think he's dangerous by how kind he actually is.
President Spheros: He'd rather die than trust him.
Betrayus: After knowing what he's done and why Buttocks is working for him in the first place, he just grew livid and started to hate him ever since
Butt-ler: Robin can't help but think that he deserves better than to be down here, and he does. Robin is an invention Butt-ler didn't think would work and tried stopping his "evil twin" from creating him, but after seeing what his true purpose was, he considers him as just a good kid.
Dr. Buttocks: It may be a bit biased since he was the one that created Robin, but Robin knows who his creator actually is and it's not some evil scientist persona. He's a man who loves science and always wanted to create things, including things that could have the same experience as living. The doctor of course just ADORES that his creation is actually alive and doing his own thing, because hey, he gave him the chance to live, not to be trapped.
