Luis Sera

A little rough, don't you think?

Luis Sera was a researcher for Osmund Saddler, who rebelled agaisnt him. Helping Leon S. Kennedy take down Los Illuminados, Luis was killed by his former master.

Early life
What is known about his past is that he was a native of the village who left to pursue a career. He and his grandfather used secret passages around the village.

When Luis returned he found the village under the influence of Osmund Saddler. With the Plagas being extracted from the mines, Sera was hired as a researcher to experiment with enhancing the creatures and their hosts (examples of enhancements include the dominant-strain Plaga, with a host example being the Novistador).

Los Illuminados
When he becomes disillusioned with Saddler, and the work he was performing for him, Sera decided to betray Saddler and steal a Plaga sample; Eventually, though, Saddler catches up with him and orders his followers to tie him up and put him in a closet to be executed. However, Leon Kennedy finds Sera in the cabin, and frees him. Sera later helps Leon and Ashley fight off a mob of Ganados.

It is later revealed that he was in league with Ada Wong, a spy sent by Albert Wesker retrieve the Plagas sample. Sera then tells Ada that he will bring it only "if she gets rid of that old man and his religious friends", then goes to get the sample and also the vaccine for Leon and Ashley.



Unfortunately, Saddler eventually catches up to Sera and impales him through the chest with his tentacle tail. 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 behavior 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. It is also mentioned in one found note that he was able to remove the Plaga egg before it hatched in his body.

Even though Sera doesn't live to see it, Leon and Ada managed to stop Lord Saddler from taking over the world, and destroy his cult in the process.

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

Trivia

 * During the Chapter where Leon and Luis fend off numerous Ganados, Luis will duck to avoid friendly fire whenever you aim in his direction but he still can be deliberately hit, and if enough damage is taken; there will be a special cutscene where Luis shoots Leon twice, once in the Carotid artery and another in the Femoral artery killing him, and saying "Adios Leon!"
 * During his conversation with Leon, Luis claimed that he had seen a t-Virus sample in a police department lab in Madrid.
 * The plaga-removing machine which Luis made is similar to the P.R.L. 412

 * If, during Separate Ways, you have Ada look at various things during Chapter 2, she will refer to Luis as "Mister Cool", The "Spaniard", and "that womanizer".
 * Luis was a smoker, as he asks Leon and Ada for a cigarette when he first meets them.*
 * Luis' bottle cap says "Did you send out those invitations?! I told you! No more than FIFTY PEOPLE!". This is a reference to when he and Leon have to defend the house from the horde of Ganados. This is the only comedic bottlecap in the game. It fits with Luis' personality, though.
 * When fighting along-side with Leon in the Cabin fight, Luis will occasionally toss Leon Flash-grenades exclaiming; "Here, use this!"

Resident Evil: The Deck Building Game
Luis is a character card in the Resident Evil DBG, first introduced in the fourth set Nightmare. Luis' effects primarily have to do with the player's discard pile. His Level 1 effect for instance, states that the player gets +1 card, but if they have a discard pile of ten or less card's they have to discard one to replace it. His Level 2 effect states that once Luis defeats an Infected, the player can move any number of cards from their discard pile to the bottom of the Inventory, potentially postponing the circulation that is always required to keep using one's cards. The gap between the amounts of Decorations needed to use these effects is so far the smallest out of all the characters in the game. He has 80 Health.
