Tam Lin is a famous fairy who was said to haunt the Carterhaugh Woods in Scotland. He supposedly lured young women away to ruin them. He was once a human who had been trapped by the Fairy Queen. A young woman named Janet is said to have fallen in love with him at one point, and finally managed to free him.
"Origin: Ireland. He guards the forest of Carterhaugh. Originally, he was a human kidnapped by the fairy queen. He was wounded while hunting in the forest, allowing the fairy queen to capture him. From there, he was meant to become a sacrifice seven years later. But through Janet's efforts and Tam Lin's strong will, he safely returned to his world."

"A fae knight of the Seelie Court, said to protect the forest of Carterhaugh. After being kidnapped by the faeries at the tender age of 9, he lived much of his life among them."
—Persona 5 Royal background
Tam Lin is the second Persona of the Faith Arcana and he can only be summoned in the Velvet Room by doing a cross fusion with Cait Sith, High Pixie, and Leanan Sidhe. He is the second of four Persona to learn the Brain Shake skill, the second of five to learn Heat Up, and the first Persona to learn Brain Buster and Brainwash Boost. When itemized through Electric Chair execution, Tam Lin will yield the Fairy Knight Armor for men, which has 170 DEF, 15 EVA, and increases the wearers Magic by 4. During a fusion alarm, Tam Lin will yield the Fairy Hero Armor instead, which has 180 DEF, 15 EVA, and increases the wearers Magic by 7.
Shadow Arihara takes the form of Tam Lin during his boss fight. When either Ann Takamaki, Makoto Niijima, Haru Okumura or Yoshizawa is in the party, he will use Womanizing to brainwash all female party members, followed by either One-shot Kill or Triple Down. He also resists Ann, Makoto and Haru's main elements, so it is strongly advised to not bring them. During the battle, Navigator dialogues and abilities are disabled, implying that Futaba Sakura is also affected by his brainwashing. If there is no female member in the party, Shadow Arihara will randomly use One-shot Kill, Triple Down, Heat Riser, Debilitate. He will also use Debilitate during One Mores. When defeated, he will drop the Agitation Crownaccessory, which allows the wearer to use Brain Jack.

Tam Lin sometimes has the same design as Cu Chulainn, with their colors being the only difference. The only games that are an exception to this are the Devil Children games (where Tam Lin and Cu Chulainn have different appearances) and Devil Survivor 2 (where Cu Chulainn uses his Devil Summoner appearance while Tam Lin still uses his design from the PlayStation artwork of Shin Megami Tensei).
