Video games as a whole are filled with loathsome, wicked villains. Men and women bent on doing nothing more than making your life a living hell. From the Final Boss in DOOM II to the Roid Rage Pyscho in Borderlands, first-person shooters are no stranger to some evil baddies.
These are best of the worst. 3 of the baddest villains you will encounter in a shooter, bar none. There might be more sadistic villains out there, a bad guy more twisted and cruel but these are our favorites.
Note: this page will contain spoilers, proceed with caution!
#3 - The Flood
Game: Halo Series
First encountered: 2001

Technically speaking, the Flood isn't really a single enemy as much as a group of enemies but holy crap are these guys bad. Making their first appearance in the first Halo game, the player first encounters the Flood about halfway through that game. Released by the Convenant, the Flood come upon Master Chief during his attempted rescue of Jacob Keyes. Overwhelmed, Keyes and his squad become assimilated by the Flood before Chief can move in and rescue them.
Why They Deserve a Spot on This List
The Flood are one of the most despised of FPS villains and for good reason. These pyschos feed off of sentient life, spreading their infection rapidly and assimilating those life forms. When infected, the host becomes one of the Flood and the vicious cycle continues. The virus consumes anything and everything in its path, with hosts growing stronger in their death and infection.
If this wasn't enough, the Flood posed such a threat to the world that the Forerunners had no choice but to kill themselves in an attempt to finish the Flood once and for all. This bastard infection is responsible for the death of an entire generation of life. The story progresses all the way through Halo 4, but this should give you an idea of the type of bad guy we're dealing with here.
#2 - Frank Fontaine
Game: BioShock
First encountered: 2007
Hands down one of the most insane twists we have ever experienced in a video game came at the hands of the bastard known as Frank Fontaine. Naturally, you think BioShock villains and your mind goes straight to Andrew Ryan, but to that we ask, 'Did you actually play BioShock?'.
Because Fontaine is about as bad as it gets, in our eyes.
Why They Deserve a Spot on This List
On a list of 'biggest douche bags', Frank Fontaine would rank pretty high. His crimes include, but are not limited to:
- Manipulating others for his own personal gain.
- Conning an entire social movement for his own personal gain.
- Pretending to be someone he wasn't for his own personal gain.
- Attempting to extend his own personal revenge to total domination.
Throughout the majority of BioShock, players are guided and assisted through their adventures by a friendly revolutionary by the name of Atlas. As things turn out, Atlas is nothing more than a front for the man previously known as Frank Fontaine, one of Andrew Ryan's biggest rivals. Fontaine manipulates, tricks and employs mind control against you to achieve his own personal plans for revenge and domination.
Yeah.
#1 - GLaDOS
Game: Portal Series
First encountered: 2007

Our number one spot goes to none other than GLaDOS, who earns her place on to this list not for her sheer wickedness or cruelty, but rather because she was such a damn good character. Valve's writing team is always amazing, but GLaDOS is perhaps their best achievement to date.
GLaDOS first appeared in 2007's Portal as the AI system responsible for testing and maintenance in the Aperture Science facility that the game takes place in. It quickly becomes clear, however, that there is a lot more to GLaDOS than first believed. As great as the character was in the first Portal, GLaDOS really came into her own in Portal 2 when the character spends more time understanding how GLaDOS came to be.
Why They Deserve a Spot on This List
What makes GLaDOS so unique is that, despite her efforts to ridicule, humiliate and manipulate the character, you can't help but enjoy these encounters. The writing is masterful and her character more in-depth than we had assumed from the first game. GLaDOS is one of the most popular characters in gaming from the last decade, and with good reason.
If you haven't had a chance to play either of the Portal games, we recommend you do so if for no other reason than to see what we mean when we say that GLaDOS is our all-time favorite FPS villian.
