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.
You must trade from Pokemon White, which instead of Tornadus, it will be Thunderus. :)
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.
You catch Thundurus, but must trade Tornadus from Pokemon Black.
no you cannot when tornadus and thunderus landorus gets mad the you have a chance to catch it
trade. no other way.
Throw a pokeball at it.
No, Thundurus can only be transfered from the original Black and White or from the Pokémon Dream Radar 3DS app.
If you mean using other peoples' thunderus and tornadus then yes but if you mean not having either one at all, then nope.
First catch Thunderus then Tornadus then go to Abundant Shrine.
yes you need to catch them because after you have caught them, you would have to go to an area where landorous appears
if you talk to the shrine with tornadus and thunderus then landorus attacks you and you can catch it in battle.
