my last bio was on Zekrom, the main legendary pokemon of white version. Thiss bio will be about reshiram. along with Zekrom, Reshiram is the first of its kind (dragon/fire type) and can learn the move fusion flare at level 50. As I said before, if you get reshiram /zekrom to use fusion flare/bolt in the same turn as the opposite move is used, the attck's power is increased. Fusion flare is a special attack, meaning that the user does not make direct contack with the foe.
Reshirams stats are almost identical to zekrom with a few minor differences. the main one being the attack strength. Zekrom's is at 150, reshiram's is at 120. where as reshiram's special attack is at 150 and zekrom's at 120.
When choosing which game to get (black or white) You really should consider the stats of the pokemon you choose. along with type matchups, etc.
FOR THE TRAINERS WHO FILL UP ALL 8 BOXES BEFORE CATCHING RESHIRAM/ZEKROM AND HAVE A FULL PARTY: don't despair, after completing the game's main story line, head over to the peak of dragonspiral tower, the legendary pokemon will be standing there, awaiting your challenge.
