Lake Valor (Japanese: リッシこRisshi Lake) is a location in the region of Sinnoh. Here, Team Galactic's Commander Saturn is battled for the first time. Within the cave in the center of the lake resides the legendary PokémonAzelf.
During the events of Pokémon Diamond, Pearl, and Platinum, Team Galactic used a Galactic Bomb to dry up the lake. The resulting earthquake was felt in Canalave City, located at the opposite end of Sinnoh. After Dialga, Palkia, or Giratina has been captured or defeated at Mt. Coronet, the lake will appear rejuvenated.
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
Lake Valor was the location of the Wallace Cup tournament and the Sinnoh Grand Festival. Like the games, the Hotel Grand Lake and Seven Stars Restaurant were located nearby, and Ash, Dawn, Brock, and May all battled at the restaurant.
In The Needs of the Three!, it was explained that Lake Valor, as well as all three of Sinnoh's lakes, are the entrances to another world where the lake guardians live, and they do not actually live in the lakes themselves.
At each of Sinnoh's lakes, a TM can be found containing a powerful move of a different elemental type. Lake Valor's TM is Template:Type2.
For some reason, the damage caused by Team Galactic's bomb is fixed when later returning to capture Azelf. Also, there appears to be the dried-up remains of a river that would flow into the lake on the northwest side that vanishes when the lake is restored.
When the bomb is set off here, it is powerful enough to be felt on the opposite end of the region, in Canalave City. Despite this, the Magikarp living in the lake are unharmed and no damage is visible to the land, besides the obvious drying up of the water.
Name origin
Valor means "courage". This is fitting, as Azelf is the Willpower Pokémon.
