Well considering you can't play with kintaro, I'm saying unblockable, seing as you can nail him while he's in his "laid down" stage, or his "getting up" stage, and if the spear is late, he does his fireball.
Yeah, I was prety sure it had been done before but couldn't find it on the forum, either way, I've capped it in relatively HQ, and it's there for others to see.
thanks for pointing it out though, cuz I wasn't sure.
