Welcome to Kingdom Hearts Answers. What would you like to know?

What block command? Do you mean the level up block?  Timelinesplitter Chaos 02:17, November 21, 2012 (UTC)

The Block Panel. You press Y and the character blocks attacks. You can link a Block lv up panel, but I don't get what it does. AkaAxl 12:09, November 21, 2012 (UTC)

Oh...My bad, lol. In any case, I think it eventually reflects attacks...Wait, maybe it allows links to it. I'm not completely sure, as it doesn't really say on the Kingdom Hearts Wiki either:  Timelinesplitter Chaos 13:44, November 21, 2012 (UTC)
