You must trade from Pokemon White, which instead of Tornadus, it will be Thunderus. :)
trade. no other way.
Throw a pokeball at it.
In Pokemon black you catch RESHIRAM and TORNADUS In Pokemon white you catch ZEKROM and THUNDERUS Sources : myself
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.
First catch Thunderus then Tornadus then go to Abundant Shrine.
You catch Thundurus, but must trade Tornadus from Pokemon Black.
if you talk to the shrine with tornadus and thunderus then landorus attacks you and you can catch it in battle.
No
You cannot obtain Thunderus in white by catching it. You must trade it in from Pokemon Black.
Needs to be traded from Pokemon White.
If you mean using other peoples' thunderus and tornadus then yes but if you mean not having either one at all, then nope.
thunderus is in pokemon white
