Grant is a character appearing in Pokémon the Series: XY, who is the Gym Leader of Cyllage City in the Kalos region.
Grant has dark skin, greyish eyes and black hair with several stones in his hair, colored yellow, red and blue. He wears a simple black shirt, grey pants and black shoes and carries the climbing equipment on his neck and around his hips.
In the Battle Chateau, Grant wears a grey suit, with a black undershirt and brown shoes. Also, he wears a formal, decorated cloak for the battles, from a red one (symbolizing a Duke) to a purple cloak (being promoted to a Grand Duke).
Grant is a calm man, who has a passion for climbing, whether walls or giant rocks. Grant believes one can do his best to overcome walls (aka obstacles) is to look up. He even has a romantic relationship with the Santalune City Gym Leader, Viola.
Season 17: XY
The heroes encountered Grant in the Battle Chateau, climbing windows. As everyone went to see the battles, Viola visited Grant, who fell down from the windows, finding the windows irresistible to climb on. When Ash had his match with Chester, Grant saw and commented how powerful Ash is, intriguing him. After the match, Grant places a white glove on Viola's shoulder, challenging her to a battle. Grant sent out Onix, while Viola sent out Surskit to battle. Viola attempted to have her Surskit use Ice Beam to freeze Onix and confuse it, but Onix used Rock Tomb, stopping Surskit from moving and using Flash Cannon to defeat it. The heroes were shocked and were told Grant is a Gym Leader from Cyllage City. Grant proposed Ash to meet him in Cyllage City for a battle.
After preparing himself, the heroes came to Cyllage City and went up to the Gym, where Grant was awaiting them. While Serena, Bonnie and Clemont took the elevator, Ash took onto Grant's challenge and climbed up the rocks. Grant asked what Ash was thinking about and Ash replied he was only looking up to climb the wall. Grant saw Ash understood that one has to find means to overcome walls - obstacles. Grant sent Onix and Ash sent Froakie to battle. Onix attempted to seal Froakie with Rock Tomb, but Froakie used Double Team and started climbing the rocks instead, defeating Onix with Water Pulse. Grant was impressed and sent Tyrunt, who dodged Froakie's Water Pulse and defeated it with Draco Meteor. Ash sent Fletchling to attack Tyrunt and managed to hit it with Steel Wing before being defeated by Dragon Tail. Ash, as his final Pokémon, sent Pikachu. Pikachu used Iron Tail on Tyrunt, who used Draco Meteor. Pikachu started climbing the chunks of rocks and used Iron Tail to deflect Rock Tomb into Tyrunt's mouth and defeat it with Thunderbolt. Grant was surprised, but congratulated Ash and gave him the Cliff Badge. As Serena proposed going to Shalour City, Grant told Ash he would have a good battle there.
Season 19: XYZ
Grant and Tyrunt, along with the other Gym Leaders, went to stop the Giant Rock from approaching the Anistar City's sundial. He noted the Giant Rock was a great "wall" he would've loved to climb up to. During the battle, Grant had Tyrunt fight the plants to let Ash and Alain continue, along with Viola and her Vivillon. However, both of them were soon bound by the roots, so Grant yelled Ash and Alain had to climb atop the Giant Rock. After the Giant Rock was stopped, Grant had Tyrunt launch an attack, which fused with others' attacks to destroy the Giant Rock. Since they failed, Grant watched as Squishy and Z-2 changed form and battled against the Giant Rock and Lysandre.
Ash remembered Grant and his Tyrunt fighting theGiant Rock with the rest when he was reflecting back on his journey.
