Err.. okay then.

You know about switches, correct? (If not, check the FAQ for more info).

Anyway, on the first page of your 2-page "target char" event, do something like this:

<>Message: "Howdy!"
<>Show Battle Animation - Explode, wait until finished, target char
<>Set Switch: 0010:Exploded

Second page is just a blank event graphic with a precondition of "Switch 0010:Exploded" is ON. Set the Event Layer to below hero, so the hero can walk over the square the character once occupied.

Edit: Also, again with the rules, but please make your thread titles more.. specific. Makes it easier for others to know what's in the thread.
