Gladion (Lightsoul)

Gladion is a major recurring character in the Lightsoul series. He joined Shadow's team in the Sun Moon series.

Prior to Lightsoul: Sun & Moon
He was originally a member of the Aether Foundation together with his mother, Lusamine, and his sister, Lillie. However, over time, he noticed his mother's obsession with the Ultra Beasts and realized that she would ruin Alola if she let Ultra Beasts into the region. For this reason, he decided to leave the foundation, only telling Wicke of his departure. Before leaving, he stole one of the three Type: Null created to be a weapon to attack Ultra Beasts.

Personality
When Gladion first appeared, he was distant from his sister because he blamed himself for why Lillie was unable to touch Pokémon. He is shown as being impatient, as seen in Revealing the Stuff of Legend!, when he demanded the guardian deities hurry up as they waited to save his mother.

As shown in Showdown on Poni Island!, Gladion has a faith in his Pokémon to let them battle each other to train, without giving them any kind of command. He also showed that he is happy whenever his Pokémon does well, as shown when he bumped his hist with one of his Lycanroc's fists after it defeated Lycanroc.
