In "Space Chicken", he was depicted as pretty shy at first, but after being around Tilly and Cricket, he became more extroverted. He is described as shy, smart, a great friend, a good problem solver, and a good decision-maker.
Prior to "Remy Rescue", he had trouble speaking up to his parents, but when it is revealed that he is to go to boarding school, and because of Cricket's assertiveness and fear of losing his best friend, Remy starts to speak up.
Remy is also depicted as someone who does not understand normal things like camping (“Wild Side”) or fishing (“Axin' Saxon”)
In "Bad Influencer" when Remy started watching Itchaboi Vlogs, he started to become self-absorbed and obnoxious, rejecting anything that isn't anything "mirabulous", hence Itchaboi's "Negate the Hate" promotion. Because of this, he ironically started snubbing Cricket over Itchaboi, preferring to do whatever he wants to do and nothing else. However, Cricket managed to talk him out of it in the end, and in return reverts to his old self.
Remy's parents are caring towards her son, and they want the best for him, as seen in "Remy Rescue" where they learn that Remy has been skipping his violin lessons, deciding that he is to go to a boarding school located outside Big City.
Once Remy stands up to his parents, they are impressed with him, allowing him to stay in Big City.
