defeating

hmm I was thinking, wouldn't it be cool if someone could defeat a ki blob? Let's say when someone's meleed you, and your down cold and they start ki blasting you and form a ki blob, then your forced to get up and teleport out or jump out or whatever, and when the kiblob explodes it might kill...

As we all know, head-on melee is growing in popularity with each passing day. What are your strategies to defeat it? I'm curious to know.
