Where is Entei in Pokemon Indigo?
You can get entei in Elite Four Garcia and multiple other rooms
you cant catch entei on Pokemon pearl. entei is a johto Pokemon and Pokemon pearl is a sinnoh game. the only way to get entei 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)
Yes, Entei does flee. After your first move, Entei will flee the scene. However, if your Pokemon is at a higher level than Entei (level 41 or higher) and has a move or ability to prevent wild Pokemon from escaping (for example, a level 42 Golbat that knows Mean Look), Entei cannot escape until the higher leveled Pokemon faints or is switched out.
