lol i just beat morty i went out the gate and entei appeared and i used a fast ball from kurt and caught it. fast balls, quick balls at the start of the battle and ultra balls.
Entei!!!
You must have chosen bulbusaur at the beginning of the game and have the pokedex eventually entei will show up when your in grass. If you didn't choose bulbusaur find someone who did get entei, if you have a Pokemon colosseum you get a shadow entei from the game.
i would say Ultra-Ball so you could save the master for Entei Suicune or Raikou pokeballs are the best balls you can use just use one of them and then do the A/B trick(hold a and b at the same time) and it should catch!
Pokemon that are like Entei and Kingler or Crabby.
A Master Ball is the ultimate Pokeball. It catches any Pokemon without fail, however, you only get one so you should pick witch Pokemon you catch with it carefully. I used mine to catch a Latios, but using it on Raikou or Entei would be just as wise. Of course this is your choice friend, but think it through ;)
One of the roaming Pokemon ex. Raikou, Entei, Latios, Latias
Sorry... Just... get Gold or Silver and trade.
Entei is only attainable in gold, silver, heart gold, and soul silver versions. If you wish to own one in emerald, your only options are to either use a game shark, or trade Entei over from gold, silver, heart gold, or soul silver versions. Not true you can capture entei in firered or leafgreen and Pokemon colosseum trade one from those games to emerald.
at lv.80
Transfer the entei from Heart Gold or Soul Silver.
Raikou, Entei, Suicune, Lugia, Ho-oh. hope this helped
yes you can i got lucky and got enti with a POKEBALL! Nice, thank you! I caught mine with fast balls. -The person who asked this question.
