One way is to block them from running away. Or you can use false swipe and let them run away. And when you guys cross paths again, you can capture it. But to make things simpler, block it and then try to capture it because your luck might not be as lucky when you try to capture it. So use the move block or some other move.
GOOD LUCK TRAINER! :)
Its easy, all you need to do is catch Lugia and the 3 like entei then take them to the dragons den, surf, then catch a dratini.
Its easy just hurt it very much but not kilt paralyze the entei if you can or use hypnosis but you don't must to do that just make it easier. then use the ultra ball. I not sure the entei will be catch directly but soon.
Entei learned roar, you have to catch it with mean look because if you don't do dat he fled. You have to buy 40 ultraballs because it is not easy to catch him. En then you have roar. Entei is lvl 40
No you cannot catch Entei in Pokemon Emerald.
You have to go to ecruteak city and meet eusine. Then entei won't be too far behind. You have to battle entei once you see him. You have no choice. Its not easy to beat him. I had to resort to my sixth Pokemon to defeat him!
No, you can catch Entei without catching Moltres.
use a masterball
Using a master ball
yes
You cannot catch Entei in Pokémon White because it is not available for capture.
You can't catch entei in Pokemon black he is on a different version
You can only catch it when steven talks to you in vermilion city when you try to get the doll for the copycat. You catch it the way you caught raikou and entei
