He loves to entertain people and make them smile. Giving those whom are extra kind to others small little gifts such as flowers, balloons, or even glitter, Splendorman enjoys giving back to them. Often times dancing to keep those entertained, he will keep at it until you are as well smiling along with him. Splendorman is also to believed to have tentacles like his younger brother, which are the same onyx color, but with thin rainbow stripes along them and bells at the ends. Though, is hasn't become official that he does have tentacles, since he has never been depicted to have such. (Information has been given by DI-LastShadow on deviantArt)
It is not known what Splendorman is (once again referring to the headcanons, he is believed to be part of a family of entities called Enders) or where he comes from, and most people are having too much fun to even care. Although, it is known that Splendorman gained popularity awhile after his brother, Slenderman became popular. It is said that him and his brother do not get along well. This is of course due to the fact that Splendorman and Slenderman are basically polar opposite to each other. It is believed that Splendorman has troubles understanding his little brother for he was always accepted for his gracious and happy emotional self, while his brother is socially unaccepted, hated, and feared.
Slenderman is more famous than his older brother though.
Splendorman is not as cool either
