Most unfair and cheap enemies ever?

[Fishyash]

You! Yeah you!

And you...

The moths in band land on rayman were THE biggest annoyances I have ever experienced EVER, dodging all your moves and then flying around at light speed in the air kicking you back and fort... countering your every move. Cheapest enemy I have ever seen.

[JackandTom]

Tabuu in Super Smash Brothers Brawl. I just found it difficult to dodge the majority of his attacks. He wasn't too bad once you had a fairly competent 2nd player.

 

[Macgyvercas]

Anything that can regenerate health faster than you can deal damage to it.

 

[Genji Bullet]

This!

Edit: Or Plesioth from Monster Hunter!

 

[Eternal_24]

Jinpachi Mishima from Tekken 5. He had an attack which was unblockable, undodgeable and took off 2/3 of your health... which he could also repeat in rapid succession.

 

[Professor James]

Deathclaws in New Vegas.

This I also like to add hunters from prototype. Seriously I just attacked you with a giant blade and a rocket launcher and you not only survive but shrug it off like it's no business and do an unblockable attack.

 

[Glademaster_v1legacy]

Seth from SF4. He would be fine if in the Arcade mode he had his normal low health and his attacks were a little lower on priority.

Every enemy ever in CoD:WaW. Their grenades are attracted to you. They also have an infinite supply of grenades. As well as an infinite wave of enemies.

Spoiler: Castlevania Medusa Heads

Spoiler: Ninja Gaiden Eagles.

I had to hide them in spoilers because looking at them too long will make me explode with nerd-rage. If you've played either game you know why.

 

[Goombuster]

Red arremer.

Anyone who played Ghosts n' goblins knows what I'm talking about.

 

[Justanothergamer300]

I don't think I need to explain myself.

 

[MaVeN1337]

Minion Ballista from Global Agenda.

Whose idea was it to give a very common enemy a cover-bypassing insta-kill attack?

Those were bad at first, Until the Dune Commander made it's way into the game.

 

[emptyother]

My allies in the call of duty series. They let the enemy charge right trough them and kill me.

 

[Kadoodle]

Anybody who has played Uncharted 2 knows what I'm about to say. Those super-juggernauts with the chain-guns, who take 4 rockets to the face before dying...and for some reason they always come in groups...

 

[Varanfan9]

The blue zombie things in Splatterhouse. If they got you in a combo it was all over for you and they could even slice your arm off.

 

[judowarrior]

Did anyone else not have trouble with the Scion/Praetorian combos in Mass Effect 2? By themselves they were manageable, but when in the same room they were annoying. The praetorians and scions had health out the wazoo, and it doesn't help that the praetorian can float over cover and the scion is essentially a tank with a sniper rifle. Also, whenever those two were together, there were always collectors, forcing you to stay in cover, but if you stay in cover the Praetorian will get you, and if you pop out to shoot the collectors the Scion will kill you. AAAAAAGGGGGGHHHHHH!!!!!!!

 

[Deadlock Radium]

The Creeper.
They sneak up on you without makind ANY noise, then blow you to shits! D:

Also, the Minecraft Ghasts. They're so bad that they made SeaNanners (!) say "What the fuck?"

 

[Kamikazi1231]

Goro from the original Mortal Kombat. He could block everything besides one specific move that you had to spam on on him over and over. I felt cheap as hell. Nothings worse then getting that far in a game to have to start all over again. Even the grand master after Goro was nothing compared to taking town that 4 armed bastard.

I was playing Red Dead Redemption: Undead Nightmare, and I was doing a mission the required me to go up into Tall Trees. I just entered the area when I heard a roar, I turn the camera backwards just in time to see a ZOMBIE BEAR swipe at my horse. My horse falls over dead, I fall off, and get this... THE ZOMBIE BEAR STARTS TO WALK AWAY. This isn't a game enemy that wanted to kill me. This was an enemy that wanted me to die a slow, painful death full of fear. It wanted me to suffer. That smug zombie bastard. I proceed to shoot it in the face for vengeance. And 12 seconds later I was mauled by a zombie cougar. Now, everytime I see a zombie bear, I will go out of my way to kill it. For my horse.
