Luis Sera

A little rough, don't you think?

Upon first meeting Leon S. Kennedy, Luis Sera claimed to have formerly worked as a police officer in Madrid. This seemed unlikely, however, as Ada's report on Sera states that he studied biochemistry at university, before going on to establish himself as a brilliant scientific researcher. With such an education, it is doubtful that Sera went into a career as a police officer. Another is the fact that according to a file, he and his grandfather used secret passages around the village.

What is known about his past is that he was a native of the village and was employed by Saddler as a researcher to find ways to strengthen the Plaga parasites. When he becomes disillusioned with Saddler, and the work he was performing for him, Sera decided to betray Saddler and steal the sample of Las Plagas; eventually, though, Saddler catches up with him and impales him through the chest with his tentacle. Before dying, Sera gives Leon some pills to suppress the growth of the Plaga in his body, as well as leaving behind all of his research notes - scattered throughout the castle and island complex. These memos provide Leon with useful information on the behaviour of Las Plagas and how to destroy many of the creatures introduced during the course of the game. The plaga-removing machine which Leon and Ashley use near the end of the game was invented by Luis Sera. It is also mentioned in one found note that he was able to remove the Plaga egg before it hatched in his body.

The "Separate Ways" scenario and "Ada's Report" documentary added to the PS2 version of the game expands on Luis's role in the game, depicting him as in league with Ada Wong and the organization she works with (a connection that was only implied in the main game).
