I am a weird person. Social interaction is one of my weak spots.

Anyway:
 * Kaisei Ryūren - the article is somewhat confusing, but there's this phrase: "Alvin is, as a matter of fact, one of the most powerful beings in existence when it comes to what he is and what powers are in his possession; a curse that turned out to be a blessing".
 * Shihouin Kurama - despite the fact he has no "X spiritual power" section he seems a better fit for Royal Guard than Gotei 13.
 * Ichimaru Fuyutama - Mary Sue. I'd go into more detail but that is actually the impression his article makes. Particularly the peculiar "Above Average Spiritual Power" section, and the mention he considers himself superior to any other Captain but his direct superior.
 * Shingi Kawahiru - I already voiced some concern regarding this character a time ago. Didn't change much since then, still an RG-class Lieutenant.

There were some others, but I decided that they were not actually overpowered. These four remain as the most baffling examples amongst the Gotei 13.
