Initially, Richarlyson seemed shy towards the members of the QSMP, before shortly warming up to his five Brazilian parents. Once he opened himself to his new parents, Richarlyson appears to be a caring egg, constantly trying to help his parents and displaying his love for them as much as he can, while also being quite aggressive and willing to fight the enemies, and even other eggs, that wronged him and/or his parents, a behavior formed due to the hostile environment he first appeared in.
