Pokemon Leaf Green Hack

[Judgment]

Hi. I´m making a small hack for Pokemon Leaf Green and i have a problem. I´m trying to make a legendary Suicune battle. The problem is that the Suicune doesn´t disappear from the screen after i´ve battled it. So how can i make the Suicune Sprite disappear right after the battle. Here is the Script:
#org $battle
lock
faceplayer
checkflag 0x206
if b_true goto $gone
message $roar
boxset 6
wildbattle 245 40 2
setflag 0x206
release
update
end

#org $roar
$roar 1 = SUICUNE:Cyyyaa!

#org $gone
$gone 1 = Gone

PS.I can post the Information of my hack if someone would like to hear.

EDIT:I got it to work now. Thanx to thethethethe´s guide.
