There are really no glitches in the game where this can happen. However, if you use a master (which every one knows so i won't belittle myself) it will work.
If you use an external game hacking source like a GameShark (for gameboy sp or color) or an action replay (for a ds), there are codes you can put into the system in the action replay or gameshark so that you can do special things.
But you'd have to Google "Action Replay for Pokemon Emerald" or something like that.
This cheats in the system may include:
-catch with no fail
-walk through walls
-unlimited health
-unlimited master balls
-unlimited rare candy
etc. etc. etc.
there ya go, have fun cheating in the game fellow Pokemon player :)
Of course, a Master Ball catches any Pokemon without fail, Legendary or not.
In battle, teleport will allow you to escape from wild encounters without fail (with the exeption of pokemon with the abilities shadow tag, or arena trap). Outside of battle, it will take you to the last pokemon center you have visited. This is the same for all other pokemon games.
You should use a "Timeball". Go in the battle, and fight 20 minutes, then you should catch without failing.
Go up to the Dotted Hole door on Six Island and have a Pokemon use Cut the door will open without fail but save after entering
In Battle: You can escape from wild Pokemon easily and without fail. It does not work in trainer battles or else it'll say it failed. In Field(Outside of battle): When you go through your Party and select the Pokemon with the move Teleport, you'll instantly go back to the latest Pokemon Center you have visited, regardless of what city/town it is in.
Use the Master Ball if you need to catch a Pokemon without fail. I'd suggest using it on a legendary, though - don't waste it on a common Pokemon.
No both in the games and in the show a masterball can catch any Pokemon without fail. It can fail but it is a 1 out of 65536 chance of failing to catch a Pokémon; this event being 8 times less likely than finding a shiny Pokémon in the wild. Plus it also depends on the catch rate. If there was a Pokemon with a lower catch rate than 3, it could fail.
that's impossible you actually cant
Well i caught mewtwo on full health doing this but... i used a great ball and repeatedly tapped a and it worked
This is impossible without the use of cheat codes, unfortunately. Only the Master Ball can catch Pokemon without fail.
one of his trick has fail
it catches any Pokemon without fail But basicaaly there for ho-oh and lugia
There isn't a way to do it. You can just try to weaken the pokémon and put it to sleep.
Pokemon the game is awesome the show is a fail
shoot him.
Zapdos will be at the Power Plant. Make sure to save before battling it to ensure success and not a FAIL at catching it. This is a freaking legendary Pokemon you won't be seeing again in the game, so catch it, don't KILL IT!
yes it does because a master ball catches pokemon without fail
