Raihan is recognized as the strongest Gym Leader in Galar. He is the self-proclaimed rival of ChampionLeon, and despite a losing streak of 0 to 10 against him, is the only person who has come close to beating him. While he specializes in the Dragon type, he will often use Pokémon of other types to set up weather conditions such as sandstorm and harsh sunlight. Raihan is often seen taking seflies on his Rotom Phone, a habit he initially picked up to remind him of the pain of defeat, but eventually this habit spread to other parts of his lifestyle.
"Raihan is commonly regarded as the most skilled Gym Leader in the Galar region. He has striven for victory in every environment, and as a result, he has adopted a battle style where he utilizes weather effects to their fullest. It is rumored that he could easily become another region's Champion should he choose to move, but it seems that to Raihan, defeating Leon is much more important. His uploaded selfies are quite popular. Occasionally he'll post a photo that only shows a sandstorm."

"Raihan started taking selfies so as to never forget the pain of his defeats, but more recently he has been taking photos showing off his training routine, his fashion choices, and the like, causing some fans to leave harsh comments whenever he loses to Leon. It's true that Raihan is on a ten-nil losing streak against Leon, but no other Pokémon Trainer has managed to KO as many of Leon's Pokémon as Raihan has. Raihan no doubt looks forward to taking a selfie after finally defeating Leon."
