User blog comment:Aizen.sama/Are Espadas, Vasto Lorde(s)?/@comment-1769234-20100421181416

I believe all the top four Espada were Vasto Lordes for if Nnoitra who's spirit energy was close on par with Kenpachi's is something to think about. He was once number 8 and became number 5 because of years of strengthening the amount and force of his spiritual power. And Ulquiorra states that all the Espada ranked four and above cannot release their zanpakutos within Los Noches for it could destroy it. I dont know if Yammy or Nel are Vasto Lordes though they may have been very strong adjuchas. Plus when Toshiro states the level of the Menous the Vasto Lordes image looks like it could have been Uliquiorra before he became an aarrancar.
