Saikar is a regular ponychan poster. He started posting on Ponychan, largely in /pony/ full time after Return of Harmony part 2 came out.
He is known for posting desaturated or "grey" images of Twilight as well as for being a massive dick. Seriously, the guy's a total tool. Nah, I'm just kidding, he's a pretty chill dude. Oh yeah, and the dude hates bananas. Apparently there was some cult member and a ritual sacrifice, I don't know the details.
it was at one time widely speculated that Saikar was truly incapable of getting banned. However, this has since been proven demonstrably false (see pic) after made a post on /meta/ so gloriously over the top a mod got jelly and removed him from the ponychan community permanently for about one hour.
