Praetor Rykard is a character in Elden Ring. He is one of Rennala's and Radagon's sons and brother to both Radahn and Ranni. While he is often depicted with red hair before his transformation in fan art, a portrait in his home depicts him with blonde hair.
This was Rykard's demi-god form before he was devoured by the God-Devouring Serpent
