Grimmjow's pretty strong, actually. Yes, he got an arm sliced by Tosen and had himself beaten down by Ichigo a few times, but let's not forget he was an Adjuchas as a Hollow and the 6th Espada, one of the strongest Arrancars in Aizen's army. Plus, it would've been 17+ months since we last saw him, and given he's alive, it's reasonable to see him stronger than before.
