Well, sometimes a roaming Pokemon will come back right away. But, nobody really knows. Today I was just searching for Pokemon to train in Eterna Forest and I kept coming across a Silcoon. It was starting to drive me crazy. So this might be close to what your situation is, my suggestion (If you are trying to find a Pokemon roaming around more than once), just keep roaming around and searching in the same place and you will probably find it again.
Attempt to catch?: When you spot the Pokemon, save in the place Terrakion is and if he faints start over (Reset DSi or turn off DS and your still in the place you saved at)............... he disappears when he faints.
That's the great thing about Pokemon Mystery Dungeon - if you lose a Pokemon after you recruit it, it goes back to the place you found it! Even legendary Pokemon return to their places for you to recruit again. Some Pokemon are exceptions - like Latias and Latios, but most of them can be recruited again.
If the first Heatran faints there is no second one. The trick is to save the game before you battle Heatran so if you kill it or if it kills you, just turn it off then back on.
Yes, you can get Azelf back if it faints during your challenge against it but it will only come back in Pokémon Platinum, Pokémon Black 2 and Pokémon White 2, it will come back once you beat the Champion regardless of whether you've already beaten the Champion or not. However if you've knocked out Azelf in Pokémon Diamond or Pearl then it will not come back.
It depends. It helps to get it with on HP by using Hyperfang or false swipe and you make it paraylzed or frozen. Also save before trying to catch ANY legendary JUST IN CASE it faints so you can just turn the power off and retry.
you cant if its a regular Pokemon the original answerer is right but if it's a ditto and you are facing a legendary you can transform into it for the length of the battle or until ditto/legendary Pokemon faints if it faints during the battle.
After you beat the elite 4 again raikou starts roaming again.
If Cresselia faints [same as any legendary pokemon] you cannot catch it ever unless you save before the battle and restart if you make a mistake.
No, like all legendary pokemon, if it faints, you can no longer catch it. Giratina is an exeption. If it faints in the Distortion world, you'll have one more chance to catch it in the Turnback Cave after you beat the league.
If you beat Dialga and Dialga faints, you can no longer catch it.
Once a legendary Pokemon has fainted it won't come back until you restart your game. This is assuming that you are talking about wild Pokemon and the ones that only appear once in the entire game.
If you battled Rayquaza and defeated it, then it's gone. You only get 1 chance to catch a legendary Pokemon.
When Articuno faints, you lost your only chance to get it. Articuno is a legendary Pokemon, and can only be battled once. If you saved beforehand, you can shut the game off and turn it back on to re-battle it. Otherwise, you can no longer get an Articuno. [blackhole23] Actually from Pokemon Platnium on the way of catching legendary pokemon has changed. If you flee or cause a stationary pokemon (such as the legendary birds in the game) then you can reappear by defeating the Elite Four again. This can be done multiple times as long as you keep defeating the Elite. For roaming Pokemon (such as Entei and Latias), if you defeat them you can go up to the person who first told you of them (Steven for Latias) in the location youfirst talked to them and they'll reappear. Hope this helps. :)
No,you can't,like all legendary Pokemon if you faint it or if she beats you can't capture her. So save the game before you try it.
Hit points are your Pokemon's health. When it runs out, your Pokemon faints. If your Pokemon faints, you can take it to a Pokemon Center or use a Revive on it to revive it.
after you get the national pokedex 2 new pages of the poketech will be added then you will see a flashing head that's him hope thet helped
inthe reverse worl and some place that's around veilstone city if you run away or it faints in the reverse world.
