You cannot obtain Thunderus in white by catching it. You must trade it in from Pokemon Black.
You must trade from Pokemon White, which instead of Tornadus, it will be Thunderus. :)
Needs to be traded from Pokemon White.
thunderus is in pokemon white
You can't get Thunderus in Pokemon Platinum at all. By then when Pokemon Platinum was made, no one knew that Pokemon Black and White were going to be made.
Thunderus is not in Pokemon Emerald.. it is in Pokemon White.. come on guys..
The only way is to trade from someone who has Pokemon white.
You catch Thundurus, but must trade Tornadus from Pokemon Black.
Thundurus, is an Electric and Flying type Pokémon
No just the last gym leader then go to Mistralton City, go on route 7 then go to the house near the places with the clowns. You see Thunderus after Tornaus in Pokemon white.
In Pokemon black you catch RESHIRAM and TORNADUS In Pokemon white you catch ZEKROM and THUNDERUS Sources : myself
You Don't Get Thunderus In Pokemon Black. You Actually Get Tornadus. To Get Thunderus, You Must Trade With Someone From White Version Who Has Him... (Tornadus, And Thunderus Are The Entei, Raikou, And Suicune Of The Unova Region, Meaning They Run Away Every Time You Enter Battle With Them. So I Suggest Saving Your Master Ball For Them.)
u can find him on route 9 after u encounter thunderus.
