Yes. You can catch all three Dogs in Gold, Silver, and Crystal. The only problem is that you have to play a lot, being that they come up at random times after you release them.
Pokemon that are like Entei and Kingler or Crabby.
There are 5. Entei, Suicune, Raikou, Ho-oh, and Lugia.
No you cannot catch Entei in Pokemon Emerald.
Pokemon crystel version
You can't catch entei in Pokemon black he is on a different version
Entei!!!
You'll find Entei in the Burned Tower with Raikou and Suicune but when you see them run off, they will be roaming around the Jotho region. Just keep traveling until you see one of them.
In Pokemon Silver its pretty much Johto so you can get Lugia, Suicune, Entei, Raikou, And Celebi as legendary. P.S. you can go to Kanto and catch Mew,Mewtwo,Moltres,Zapdos,Articuno,and i found a shiny pigeyot.
Sorry... Just... get Gold or Silver and trade.
The Pokeathlon isn't in Pokemon Silver version.
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.
Transfer the entei from Heart Gold or Soul Silver.
