Sugimura in order to make the writing more appealing. Sugimura often revised the Resident Evil 2 scenario such as the multiple interactions the two player characters have and what weapon should each acquire. Elements from Leon's backstory from the Resident Evil 2 manual indicating having had a split with a woman were based on Kamiya's own life. Kamiya further commented that the relationship Leon has with Ada Wong is manipulative by the latter. Speaking about the relationship between Leon and Ada, Urb said: "It's kind of like Mulder and Scully and an X-Files type of deal, where you're waiting for it to happen, but it never does. Maybe in the next one, I'm hoping." Though director Makoto Kamiya initially wanted the film Resident Evil: Damnation to follow the dysfunctional romance between Leon and Ada, such idea was scrapped.

Leon was announced as Resident Evil 4s protagonist in November 2002. As the game was developed, it was intended that Leon would be infected with the Progenitor virus.

In a documentary explaining the conception of the game's characters, it was stated that Leon was intended to "look tougher, but also cool". His face was modeled after the game's animation department director Christian Duerre. Masaki Yamanaka explains the change to Leon from Resident Evil 2 as being due to the experience he has gained since that game. He was buffed up accordingly, but Yamanaka did not want him "too buffed out". During the development of Resident Evil: Degeneration, producer Hiroyuki Kobayashi stated that Leon and Claire returned as protagonists due to their relationship and role in Resident Evil 2 and the recent release of Resident Evil 4. Leon was also added too because of his experience, especially with how he works with the new character Angela. The producer said in 2009 would like to make another game
