Unfortunately, Reshiram is a legendary Pokemon, therefore it does not evolve.
reshiram does not evolve
Unfortunately, Reshiram cannot evolve like legendaries in all generations of games e.g. Zapdos or Mewtwo never evolve. Although odd hacks could be produced, officially there are no evolutions for Reshiram. Pokemon Wiki Answers Team
lv 100 its good my reshiram has it
There are different ways of evolving Pokémon in Pokémon Black. Most evolve by leveling up, others evolve by using a type of stone on them. But not all Pokémon can evolve. Reshiram and Zekrom is a good example to that.
Nothing - Reshiram doesn't evolve. Also, Reshiram is only in the Unova region (Black and White 1 and 2) so why is this question in Diamond, Pearl and Platinum?
reshiram will learn blue flare at level 100 and Zekrom will learn Bolt STrike at level 100!
It depends on the level a level 100 reshiram could destroy a lv 10 zekrom it depends on the level cause they're both are equal even a level 100 zigzagoon can destroy a lv 50 reshiram
