you need a wobbufet or wynaut because they have shadow tag so put that Pokemon in the front of your party or you can get a octillery if your trying to catch a fleeing Pokemon
try using the move 'mean look' on it so it cant escape.
There are no items that stop Pokemon from fleeing in battle in Pokemon soulsilver.Although this is true:You can catch a Pokemon that knows, Arena trap,and/or a Pokemon that knows mean look, such as a Ghastly.
Have a Pokemon with the move called Mean Look, which Golbat is a primary choice to have this move. The move Mean Look prevents the Pokemon from fleeing or switching out during a battle and can be very useful in a battle like this. You cannot stop Mesprit from permanently fleeing, however. It is recommended to bring a Pokemon with any sleep status moves like: Hypnosis, Sleep Powder, Yawn, etc. to further the effect.
If Cresselia disappeared off of your map completely, then you have already caught Cresselia, or there is a glitch in your game where Cresselia has just disappeared off of your map. Further details would be needed for a more in-depth assessment as to why this has happened if neither of the two reasons stated are why Cresselia isn't on your map.
You can use a Pokémon with the ability Shadow Tag(Wobbuffet) to stop it from fleeing.
Try catching a wobbufet or something with the ability shadow tag or arena trap. They stop wild Pokemon from fleeing.
they used their swords and fists to stop them, and they cursed them
Mean Look prevents a pokemon from fleeing in from battle. It's useful when catching Cresselia and Mesprit, if that's what you're after.
I think you can use it on Cresselia because if you make Masprite faint in will stop running and you can catch is, but not Cresselia! I haven't figured out how to get arceus yet, sorry!!!
mean look= prevent fleeing, false swipe= left with only 1 hp left, dusk balls, ultra balls, and quick balls.
if you mean vanish as in flee like mesprit, cresselia, moltres zapdos and articuno, its because they are supposed to do that and they do that in platinum and diamond too. you can only get moltres zapdos and articuno in platinum. to stop them from fleeing, you should have masterballs or a TRAPINCH in your first slot but you cant switch out because it knows sand trap or whatever its called to stop Pokemon from fleeing or have a haunter or any ghost Pokemon that knows mean look or a sudowoodo that knows block and USE those moves IMMEDIATELY when you see them. hope i helped! :)
Pokemon with mean look can stop Pokemon from fleeing
It is when the operator of the vehicle intentionally maneuvers so as not to be stopped by the traffic stop and continuing on when ordered to stop.
you cant stupid
After a little while into the post game, Cresselia starts appearing into your dreams or at least Darkrai is. He was pretending to be Cresselia. Cresselia is really good, but the Cresselia in the dreams are Darkrai's doing.
