Eden Mori is the charismatic sponsor of Team Mosaic. A former supervillain, Eden utilizes his cunning and knack for schemes instead to make connections and develop strategies for the team. While Eden has turned to the good side, he hasn't lost any of his flair for the dramatic. He often weats ostentatious clothing and speaks in flowery language at home with his roots in Regency era England. He is married to the hero that took him down, Toshiaki Mori. The two are deeply in love, although their tendencies to play elaborate and sometimes deadly games with each other can make it difficult to discern at first.

Eden has the ability to astral project; he can seperate his soul from his body and travel invisibly through the world.
