Simple. You just battle the elite four again and you can challenge him
shoot alder with a gun
After beating Black Tower, you can see Benga again at Alder's house in Floccesy, and he'll give you a Shiny Gible holding an EXP share.
When you first beat the Elite Four, you will find that N has beaten the champion Alder, but after beating N in his castle, he will fly away on Reshiram and Alder will return to being the champion. But I personally (others agree) think that N is the champion. After all, he did beat Alder. But if you want fact and not opinion, Alder is the champion.
alder the champion has an accelgor bug type.bouffalant normal type. vanilluxe ice type. volcarona bug/fire.excavalier bug/steel.druddigon dragon/rock after you beat him,he'll take you to hall of fame.
When you go to Twist Mountain and have to battle Cheren, Alder will give it to you soon after you beat Cheren.

after beating alder and seeing or catching all Pokemon

Well if you beat elite four then beat alder then you must go to Cynthia (the sinnoh region champion) in undella town.when u go to undella town go left from the Pokemon center then go to the first house you see.go in and battle her.*HER POKEMON ARE GOING TO BE ABOUT LEVEL.75-LEVEL.80, SO BE CAREFUL BRING STRONG POKEMON WITH YOU...*Good Luck :)
Mostly Pokemon that have high stats, example: final evolution of strong Pokemon and Reshiram or Zekrom. check bulbipedia for Pokemon with high stat totals
you must once more beat the elite 4 then the spot will gloe you go there!
you dont battle alder n becomes the champion so you battle him then (if you beat him) you battle ghetsis.
You have to get the white orb. then when you beat the elite four and go to alder n is there. later when you battle him reshiram comes out of the orb I hope this helped! :) rabidrabit
If you defeat the Elite Four Twice, you will have the opportunity to battle the Champion, Alder. He has mostly Level 72 to Level 75 Pokemon.
When you first beat the Elite Four, you will find that N has beaten the champion Alder, but after beating N in his castle, he will fly away on Reshiram and Alder will return to being the champion. But I personally (others agree) think that N is the champion. After all, he did beat Alder. But if you want fact and not opinion, Alder is the champion.
you have to find all the seven sages ,beat Cynthia ,alder and the elite four.
