User blog comment:Njalm2/Fanon Canon - Grimmjow's Espada!/@comment-2089817-20150116144217/@comment-18812574-20150116160924

That was my biggest beef with it: If you are going to go for 13, why not just try and outnumber the Gotei 13 in the first place? 14, 15, 20, etc. Of course the biggest thing here is that they need to be Espada, and possess that level of power.

In my opinion, the only reason Aizen only had ten/nine Espada in the first place was because he couldn't find anybody else in Hueco Mundo that could match that level of power. He tried to make another one with Wanderweis, and we all know how that one went down. Then, of course, there are the Privarron and Luppi to shoot down that theory... nevermind. X_x

I like Z's suggestion of making 11 (or whatever rank) the designated Exequisas leader, but I don't know if Grimm would even want/need an Exequisas, kind of seemed like an "Aizen only" sort of a thing to me.

Anyway, I am not personally partial to any number we decide to go with. (Let's make it 300 and call it good, then their new uniforms can all be toga and the like: "This is SPARTA!!!!")
