Not their personal pokémon obviously, but yessss, the pokémon they have are possible to catch, twill be hard though, if you tell me what elite four you're on about i can tell you where to find the basic forms of their pokémon, and how to evolve them:)
You do not catch the elite four in any of the Pokémon games as they are not Pokémon. They are trainers who you have to beat.
In Pokemon League
only if you have the catch trainers Pokemon code
pickachoo
yes you beat the elite four.
You should train your Pokemon until they strong enough to challenge the elite four, train your Pokemon from 50->70... if you catch one lengendary Pokemon that's will be perfect!But you just only catch kyogre!
The Elite Fours Pokemon are all in their 50s. The Champion at the end of the Elite Four has 60s though.
In Pokemon League
they dont have any.
no
there are 4 elite fours
It depends on your starter.
there the same
errr 4, u gtta fight the cythina the champion straight after the elite 4
You have to defeat the elite four then you can catch the legendary
only if you have the catch trainers Pokemon code
You have to catch at least 60 Pokemon and you have to beat the elite four including your rivalyou get it from oak after you beat the elite four and the elite four champion
You Have To Beat All Of The Gyms, Elite Fours And the Champions. But Its Complicated To Find Legendaries.
