NO.Unless you trade with someone wirelessly
You can't. You have to migrate from LeafGreen or FireRed.
you cant catch entei on Pokemon pearl. entei is a johto Pokemon and Pokemon pearl is a sinnoh game. the only way to getentei is to trade it over from another game games compatible are Pokemon diamond, Pokemon platinum, Pokemon soulsilver and Pokemon heartgold. the last two i am sure you can get entei. (i have seen it in the wild)
entei is a roming Pokemon of Johto. to catch it u have to chase it. if u run or use your bike it will run somewhere else. it is similar to catching Mesprit in Pokemon Diamond,pearl,or platinum.
No you cannot catch Entei in Pokemon Emerald.
To get Entei in your Pokedex for Pokemon Platinum, you must migrate the Pokemon from FireRed or LeafGreen. You may also get it from a Gameboy Advance Game that has obtained the Entei from Pokemon Colosseum. Alternatively, you can catch the Pokemon in HeartGold and SoulSilver and trade it to your Platinum game. It is found after being released from the Burned Tower in Ecruteak City, though you have to track it through Johto with your PokeGear's Map Card.
Entei, Raikou, and Suicune are NOT obtainable in Pokemon Platinum.You will either need to catch them in Firered/Leafgreen and migrate them or trade with someone else that has them.
no u cant...........
You can't catch entei in Pokemon black he is on a different version
Its not Suicune,Entei,and Raikou its Moltres,Zapdos,and Aritcuno.
cheat or trade
Entei is only obtainable if you Migrate it from FireRed Or LeafGreen, or if you migrate it from another GBA game that has traded with Colosseum for Entei. So, you can't catch Entei in-game on platinum. You can only trade for it.
You can't catch it in the wild or special places. You have to transfer it from Pokemon Pearl, Diamond, Platinum, Heart Gold, or Soul Silver from the Transfer Machine in the Transfer Lab.
