Jerco's Relationship with theTeen Titan Characters

TEEN TITANS
Robin
Out of everyone in the Teen Titan universe, Robin is probably one of the only individuals who Jerco respects the most. This is proven after Jerco goes out of his way to save Robin prior to being coarsely plunged into a frozen river.
The two share a mutual respect, and are constantly trying to even the odds of "who owes who".
Jerco heeds Robin's advice, and follows his orders most of the time.

Cyborg
The relationship between Jerco and Cyborg is tense.
Jerco knows that Cyborg doesn't trust him, so both his physical and emotional walls are up when Cyborg is present.
Cybrog feels that Jerco is using Robin as a means to let him stay in the tower. He also feels that Jerco is untrustworthy (due to his frequent thievery), and feels slightly jealous between the brotherly interactions between Jerco and Beast Boy.
Cyborg dislikes Jerco. In turn, Jerco alienates Cyborg.

Raven
I'm pretty sure that if you looked hard enough, you still wouldn't find much of a relationship between Jerco and Raven.
Though they don't agree on everything, they don't argue with eachother. In fact, very little interaction happens between them.
Raven leaves Jerco alone, and Jerco leaves Raven alone. That's it.

Starfire
Jerco tolerates Starfire... to an extent. With Starfire being fascinated by Jerco's abilities and alien race, she fawns over him as if he were a fluffy baby kitten. Jerco is polite to her because she is to innocent and naive (and because of her closeness to Robin); but with all her hormones flying around his head, his anxiety shoots off the charts and sometimes he just has to escape.

Beastboy
In a way, Beast Boy and Jerco act like they are brothers.
Jerco is more than willing to get into trouble with Beast Boy, but usually ends up abandoning him when they are caught.
Both are constantly pranking eachother, using their powers to their advantage (and sometimes disadvantage).
Beast Boy was the first titan to discover that Jerco was invisible, but treated him with excitement instead of freaking out.

HIVE 5
Mammoth
Jerco knows that Mammoth will snap him like a twig, and will only confront the behemoth from behind.
Jerco uses guile and pestering to take down the big guy.
Mammoth hates it. And he hates the fact that Jerco made him believe that he was a ghost on their first encounter.

Jinx
Jinx thinks that Jerco is an unnatural being of much rarity that deserves respect despite his allegiance with the Teen Titans.
Jerco uses this to his advantage.

Gizmo
Gizmo considers Jerco weak, puny, and pathetic.
Jerco just shrugs and often expresses a laugh, as he is able to easily defeat the little villain.

PARANOVA
Jerco hates their guts. Upon contact, this is the only time that Jerco will ever show any urge to slaughter them all.
ParaNova sees Jerco as a science experiment that can be tossed away whenever it is rendered depleted of usefulness (AKA, DEAD), but ParaNova has everyone believing that they work for the good of the people.
Anything or anyone affiliated with the organization, Jerco will disappear from, and do everything to sully their name.

SLADE
Jerco gets the shivers every time he sees, or hears Slade. Jerco claims that he doesn't fear Slade, but nonetheless, Jerco vanishes on sight.
