Umbra Gym

The Umbra City Gym, known as the Umbra Gym, is the sixth Gym in the Tentin Region, located in Umbra City.

The Gym Leader is Criss, a self-proclaimed "emo boy" who has an interest in anime.

In Tentin Redux, after the player becomes Champion, the player can talk to Criss, who had received a Reveal Glass from Talia. After this, Criss will be at the shrine where Tornadus (if the player is male) or Thundurus (if the player is female).

In The Light in Our Hearts, Criss is instead an avid heavy metal fan, and will comment on how his headbangs are the best anyone will ever see.

Also in The Light in Our Hearts, all of the battles that take place in the Umbra Gym are subject to Inverse battle rules.

Trivia
In Return to Tentin, the Gym Trainers reference different anime through their dialogue.

 * Psychic Paula references Cory in the House in her pre-battle dialogue.
 * Criss references Dragon Ball Z by stating after the Gym battle, "Your power levels were over 9000!"


 * In The Light in Our Hearts, the Gym Trainers instead reference members of the power metal band DragonForce.
 * Also in The Light in Our Hearts, once Criss is down to his final Pokémon, an instrumental version of Through the Fire and Flames by DragonForce will play.
