User blog comment:Njalm2/Fanon Canon - Grimmjow's Espada!/@comment-136273-20150116095015/@comment-3403804-20150116151344

Aha. Well, doesn't that depend more on his relation to Grimmjow then? If he's one of the highest ranking Espada then it's more likely that Grimmjow would be a bit more cautious and reserved around him. So if he wants to influence Grimmjow somehow, which I'm entirely open for by the way, then being lower-ranked might work just as well, perhaps even better.

If his goal would require him to kill Grimmjow it probably wouldn't be any more difficult for him to accomplish based on his rank, Grimmjow is as strong as he is, and Voldan is likewise as strong as he is, Voldan's level of power isn't decided by the Espada ranking, it's largely decided by the article itself.
