Lombre is a resident of Pokémon Square who is friendly with the player and partner. He was hesitant in attacking the player when the residents were told that the player was causing the natural disasters but did so anyway. He then took part in the chase of them. He was happy to find out that they were cleared of all charges and welcomed them back. When Shiftry called lots of rescue teams together, Lombre stopped the player and partner volunteering to go and fight Groudon as there were more experienced rescue teams there.
Lombre was later at Hill of the Ancients where he celebrated with the player and partner when they helped to get the falling star destroyed.
