Grimmjow Jaegerjaquez

Well there is one thing about him.

HE IS ALIVE ! ! !

This moment is indescribable, one fucking FTW moment. You pray and pray, and then wish come true. Thank you Tite Kubo.

Last time when we saw him, he was fighting ichigo. Few moments after his Resurrection ability has worn of, he was struck by Nnoitra's Zanpakuto.

After that, we don't ever hear anything about him. We don't even see if he is dead or not. So mystery remained, until few weeks ago when we saw this scene in bleach chapter 500.

This was interesting scene where we wondered who's Zanpakuto it was. I immediately suspected who other than Grimmjow. Either him or Isshin. As manga progressed i have not paid attention on that at all.
Until last week when i saw this scene.

I was like OMG WE WILL FINALLY GOING TO SEE WHO IT WAS.
But only in next chapter. That was one of the longest fucking week i had to wait for chapter.
So finally, after it was released, i was too excited. I navigated to my usual site where i read my manga chapters and damn, site was unavailable. Damn, i hate when this happens on best part. So i navigated to  another manga site. And know what happened? That site was unavailable too. The moment i saw that sign I WAS FUCKING PISSED OFF. Why now, when the best chapter i was waiting so looouuuuuuong (that's term for long week) damn chapter that now i can't even read. I searched for first another manga site and i was lucky this time.
So how Grimmjow looks now? well im not sure because it wasn't officially confirmed that Grimmjow was present. We only see Ichigo recognizing his voice, and also we see his hand. Let me show you.

Set your focus on third's panel left side, just little bit left from chat bubble that says "hey, captain!!!"

You see it? It resembles a lot like his hand. And not just hand. His insults resembles like Grimmjow's.

Unfortunately for us, Tite made us wait for another series of chapters to see the truth. Till then, mystery still (officially) remains.
