Jagan appears in Seiken Densetsu 3, where he is one of the henchmen of the Dark Prince. His identity and his past are unknown... He is a master of dark magic. He seems to be everywhere. He has a distinctive vampiric theme, down to one of his attacks depicting him sucking the players blood.
Jagan appears along with two monsters, a Queen Carmilla and a Wolf Devil. He uses many powerful Darkness-element spells, such as Black Rain, Dark Force, and Death Spell and he uses many special magic, such as Ghost Road, Psychowave. If you dont kill Queen Carmilla and Wolf Devil, you can't damage him. The special magic psychowave projects you across the battle's map. It is best to fight him without using magic, as he seems to be programmed to counter your magic spells with one of his own. If you don't cast any spells, he will only cast a couple spells throughout the battle, making the fight much easier. Note that most level 2 and 3 Techs count as magic spells, and Jagan will respond to them with devastating magic.
- Jagan's appearance and vampiric nature make him similar to Count Lee
