Nikolai Pfeiffer's Links
He sees Sky as his little brother since he's older than him(and taller). Isn't really doing anything brother-like though besides hanging around Sky a lot.
As a child was fascinated by him and his powers and still is to be honest.
Often brings his son with him and decided for himself that Sky is the uncle.
Never actively said he liked Ri-Ri to hang around him but also never made clear that he DOESN'T want it to happen.
Along the way there was hate as well as spite for this man but Sky overcame it over time and actually started to accept him the way he was. Still gets annoyed by Ri-Ri's rather obnoxious behaviour sometimes though.
