A Dark-type Gym Leader.
About
Pocket Monsters, or Pokémon for short—mysterious creatures that inhabit this world. They are the wondrous inhabitants of this planet. They can be seen everywhere: in forests, in the sky, in the sea, in cities, and all across the globe. There are 100, 200, 300, or perhaps even more species. Humans and Pokémon form various bonds and live together in this world. There are as many dreams as there are Pokémon, and as many adventures waiting to be had.
Set in the Wareware Region.
In every region, there are several "Gym Leaders," the "Elite Four," and a "Regional Champion." Niisan is both a Gym Leader and a member of the Elite Four.
Niisan's Gym is incredibly clean and spans six floors. The reception is on the first floor, and there are battlefields both outside and on the rooftop.
