My isekai journey

Leo, a mysterious traveler, embarks on a journey through various worlds, accompanied by his loyal and ever-expanding harem. Yor Briar narrows her eyes, whispering, "Who is this shadow you seek?" Diana coldly informs Agent 47, "Your next assignment... is to hunt someone called Leo." Yami smirks "Let's see the how strong you are". Wesker grins menacingly and says, "Bring me this Leo. It's time we meet." The worlds will be from anime, movies,games and TV shows. The character is overpowered and mainly its wish fulfillment type. I will not focus on harem much but will take any girl i like. and development or romance will be up to me.
