Walter Marvin Koenig (born September 14, 1936) is an American actor (though his parents were Russian immigrants) who originated the role of Pavel Chekov on ''[[Series/StarTrekTheOriginalSeries Star Trek]]'', and Bester on ''Series/BabylonFive''.

!!This actor provides examples of:

* DeadpanSnarker: His real-life tendency to be this was put to maximum effect on ''WesternAnimation/{{Futurama}}'', where pretty much everything out of Koenig's mouth was a CrowningMomentOfFunny.
* HeterosexualLifePartners: With Creator/GeorgeTakei. Not only did George ask him to be the best man at his wedding, but when he was asked if Sulu had a middle name, he suggested "Walter", in honor of Koenig.
* OlderThanHeLooks: Played with, along with DawsonCasting. He was 30 when he joined the cast of Star Trek, playing 22 year old Chekov. Throughout the movies he still maintained much of his youthful looks, even as Chekov himself approached middle age.
* PlayingAgainstType: One will frequently need to remind himself that this is the same actor who played Chekov when watching him as Bester. Koenig eventually invoked this and stated that, partly for this reason, Bester is the role that he's most fond of.
* SelfDeprecation: E.g., the name of his autobiography is ''Warped Factors: A Neurotic's Guide to the Universe''
