Rei Saiko

Rei Saiko (西古レイ) is a character from the MegaMan Battle Network series. His NetNavi is FlashMan.EXE and is a member of the WWW. Rei is left unamed in the games.

Personality
In the games, Rei is very loyal to the WWW and Lord Wily. He is also ruthless and ambitious, attempting to kill Lan for a promotion. Rei does not readily accept defeat and after FlashMan is defeated, he often commands him to keep fighting, to the point of deletion.

MegaMan Battle Network 3
Rei sneaks into Lan's school and breaks into the teacher's lounge to steal the TetraCodes for Lord Wily. When Mayl, Dex, and Yai arrive to try and stop him, Rei hypnotizes Lan's friends and makes them act like zombies. Lan runs away to avoid hypnosis and returns later with an umbrella. The umbrella deflects the hypnosis rays and allows Lan to jack-in and stop FlashMan. Lan and MegaMan.EXE defeat FlashMan.EXE, but Rei orders FlashMan to continue fighting. FlashMan explodes and leaves MegaMan with a bug.

Rei later appears in Castle Wily, giving Lord Wily the TetraCode.

He appears again in Castle Wily when Lord Wily is announcing his plans for world domination with the other WWW members. Rei hooks up to a Transmission chair and goes into the Cyberworld to help stop Lan. He uses Full Synchro to fuse with FlashMan and challenges Lan, but is defeated by him. He attempts to self destruct, but KingMan deletes him.

He is briefly mentioned later, when they say that the WWW members are in the hospital.
