After defeating N you can go back to the Pokemon league and batle him.mHis Pokemon are at about level 75 so you should battle him with about pokemon in there lvl 80s or 90s.
shoot alder with a gun
Alder is only in pokemon black or white.
look for the seven sgaes if u did that ur done
you have to find all the seven sages ,beat Cynthia ,alder and the elite four.
you have to beat the elite four on white and when you come out of the pokemon league, champion alder will come out too and give it to you
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.
trainer n he beats alder
after beating alder and seeing or catching all Pokemon
After beating Benga in the White Treehollow, he will give you a Shiny Dratini however you will have to get it from him at Alder's House in Floccesy Town.
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.
at the end of it
