HAHA, sweet, yeah i've seen a few MLP/Sailor Moon Crossover images, but haven't seen that one before, thats a pretty sweet fan vector. Have to add that to my collection of pony pics, thanks!
And speaking of crossovers, This Pic was posted on the offical Mass Effect Facebook Wall. (the fans of ME obviously weren't too happy about it of course.) But yeah, Ponynet is slowly assimilating all. (seriously Skynet ain't got nothin on the herd, lol.)
