TBH I think the blooper should be named one of the most annoying enemies ever. It stalks you, swims up and down and is incredibly hard to hit with the fire flower, which is the only way to kill them.
These scion mother humpers in Mass Effect 2. They take horrible amount of damage and the shockwave-gun or whatever is ridiculously overpowered. Also the husks in general were a moderate pain in the ass imo. Great game in general though.
Seth. (Street Fighter 4)
You thought Dhalsim’s hand-stretch was annoying? You thought Zangief’s grabs were annoying? You think Guile’s Sonic Boom is annoying? (especially when someone doesn’t need to do the joystick-combo to do it)
Meet Seth and get them all for the price of one. The main reason I haven’t managed to beat Easy mode with every character.
Yeah, they bugged the shit out of me.
… 
Antlions :fffuuu:
The HECU are the most favorable enemies I’ve had in Half-Life. I usually snipe them before they see me or flush them out with grenades, satchels, or snarks. Love using the .357 Magnum and MP5 grenades.
Man i Hate Them too. And it never helps that there are like thousands of Husks just randomly wandering arround smacking you when your trying to stay in cover.
Oh and Mimes from Shadow Madness they only do like 1 damage a hit but i hate being forced to fight them when im to lasy to duck.
Holy shit YESS that is one annoying motherfucker right there.
Getting ex-thrown or hit like 12 times by his shoryuken-something move is a pain in the ass.
I also loved getting killed by his ultra when he had a few pixels of health left.
If you think that they’re bad just take a look at the Wraith’s in TES4: Oblivion. Simply put, they basically can’t be killed. Yeah, that’s right, Bethesda made one of its enemies that are pretty common in underground places,almost immortal. It’s still a great game though.
Yours Sincerely,

Any non-organic flying enemies. Recently, the laser-shooting things from FEAR annoyed the fuck out of me… they do a lot of damage and would be horrible if it weren’t for bullet time.

ASSUMING DIRECT CONTROL + Insanity difficulty. 'Nuff said.
Jockeys friggin’ annoying
I mean some new maps, new skins, mobile hunter, boomer with acid damage, and a half tank isn’t a sequel
- The female latex killers from HL1. They were too fast and totally impossible to kill for me.
- The hammer-throwing green monkey things from Super Mario, they jumped all over the place and avoiding the hammers was nearly impossible.
- Antlions: I hate them, they’re an infinite amount of them, so it’s a waste of ammo to kill them, but they kill you pretty fast. Also they’re ugly and not scary like the other HL1-2 monsters.
- Antlion guards: Same thing, hate them, they’re annoying.
- Voltogors (or whatever they’re called, the big antlion-ish creatures from Opposing Force): I hate them too. Hard to kill. Stupid sounds. Ugly. Many of them.
These fuckers from Return to Castle Wolfenstein…
Hammer Bros. Yes they’re annoying. You’ve never seen a Boomerang Bro though. Or a Sledge Bro. Those are way worse.
OH. How could I forget ROBO FUCKING RED.
Talk about rape. He shoots 22 BULLETS IN A TRIANGLE PATTERN IN ABOUT 4 SECONDS. HE IS 4 TIMES AS LARGE AS KEEN. FUHHHHHHHHHHH.]
EDIT: AND INVINCIBLE. (Forgot about that.)
Gargantua in Half-Life 1…very annoying when you’re up against a monster you can’t kill with weapons! And the Antlions in Half-Life 2 were also annoying. I hope in HL 3 they go back to Black Mesa or somewhere similar…I just wasn’t very fond of the whole europe thing with HL2.
