N's Reshiram - Pokémon Generations (2016)

Listed as the Vast White Pokémon, Reshiram was one of three legendary dragons in the Unova region, making up the Tao trinity. A being of ice and draconic magic, their body was said to have been destroyed in battle many years ago and sealed in the Light Stone. Remaining petrified, it was said that only a hero with a firm belief in truth could awaken them from their slumber.

Ultimately released by the trainer N, Reshiram became his faithful partner, able to communicate with one another.

Sensing that Kyurem's power was being exploited and abused, they carried N to the Great Chasm, standing alongside the former Team Plasma monarch as he attempted to end the machinations of his adopted father Ghetsis.

Neutralising Kyurem's blizzard with a single blast, he was forced to take to the skies after Ghetsis activated the DNA Splicers. However, despite their best efforts, they were struck by one of Kyurem's energy blasts and reverted into the Light Stone. They were quickly absorbed into Kyurem's body, bonding the two and transforming them into White Kyurem.

Although incapacitated within White Kyurem's body, Reshiram was still able to call out to N, reassuring his friend that the process could be reversed.
