119's meh compared to 118. But it's some nice background info. Turns out Ikkaku's had his Bankai for quite some time hehe.
I think he recently learned it after the fight with ichigo he would've used it as a last resort but he didnt so i think it was a bit after he fought with ichigo. His bankai is cool but its mostly power its basically one attack at its full strength before it breaks
I doubt ichigo will stand a chance though, reminding that Grimmjow is a Vastlord who turned into an Arrancar.
