yes you need to catch them because after you have caught them, you would have to go to an area where landorous appears
You must trade from Pokemon White, which instead of Tornadus, it will be Thunderus. :)
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
If you mean using other peoples' thunderus and tornadus then yes but if you mean not having either one at all, then nope.
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.)
In Pokemon black you catch RESHIRAM and TORNADUS In Pokemon white you catch ZEKROM and THUNDERUS Sources : myself
Thundorus has to be traded in from white whereas tornadus can be caught as soon as you reach route 10 in black
White 2: White Kyurem Black 2: Black Kyurem Black 2 and White 2: Therian forms of Tornadus, Thunderus and Landorus.
The legendary Pokemon in Pokemon black is Reshiram and the legendary Pokemon in Pokemon white is Zekrom. There is Tornadus on Pokemon black and Thunderus on white. There is also Landorus which you get from obtaining Tornadus on White along with owning a Thunderus and vice versa for Black. You must visit the Abundant Shrine with Tornadus and Thunderus in your party for Landorus to appear. You can get Virizion from Pinwheel Forest, Cobalion from Mistralton Caves and Terrakion from Victory Road . Victini is available on Liberty Garden if you got the event for the Liberty Ticket. You can get Zoroark from Lostlorn Forest if you have at least one Shiny Raikou, Suicune or Entei. There is Kyruem too, at the Giant Chasm after defeating the Elite Four.
That's Landorus. You have to have Tornadus (After Virizion) and Thunderus (Before Reshiram) in the same game. Thunderus is White-exlusive and Tornadus is Black-exlusive. You have to have both games or trade from a friend to get the other. Go to the Abundant Shrine with Both of them in your Party and Landorus will be there
That would be Landourus.
Victini, Reshiram(black only), Zekrom(white only), Cobalion, Terrakion, Verizion, Landorus, Kyurem, Tornadus, and Thunderus.
