Red

Red is the leader of the 5th Sigil Hall, the Hall of Legends, and is revered as a legendary trainer by several important NPCs, some of which are part of the Elite Four.

In the games
Red is located in Varlox Cave which is accessed to the north of Zarivar Town. He is encountered only after beating all of the other Sigil Halls first, at which point he will battle the player as expected of a Sigil Hall leader.

After the player defeats Red, Odin/Zeus appears and is ready to battle Red but realizes all of Red's Pokémon have already fainted because the player defeated Red in advance. Odin/Zeus sends out Divaevus and uses Red as a sacrifice to make it more powerful. After Red dies, Odin/Zeus challenges the player without allowing the protagonist to heal or save in between battles.

Though Red never returns to life, the player may have a rematch against him any time they desire by using Tesseract where he used to stand in Varlox Cave.
