Lucas (コウキ, Kōki) is the male choice for the player character in Diamond, Pearl, and Platinum. His female counterpart is Dawn.


Pokémon Diamond, Pearl and Pokemon Platinum

If the player chooses to play as a female in Pokémon Diamond Pearl, or Platinum, Lucas will be Professor Rowan's assistant, choosing the starter Pokémon that the player's starter Pokémon is strong against.

Lucas apparently became a trainer before the player, assisting the professor in his quest to fill the Pokedex. At first, he may seem arrogant, but later becomes friends with the player. He has a little sister who will tell the player if there is a mass outbreak; a phenomena in which rare Pokémon appear in a specific location in which the Pokémon would not normally appear.
