The first video game enemy that you killed.

[Racistman3d]

One of the goons from 007 goldeneye

 

[Singularly Datarific]

My dad's work folder.
Good times

 

[Primee133]

Doom Z-sec soldier.

 

[Aggressor and Usurper]

A Pidgey. Ah, good times...

 

[mrhappyface]

I also remember my first hack and slasher. It was a Dumah vampire.

 

[robert022614]

some nazi on wolfenstein 3d

 

[SilverUchiha]

It would be either a Goomba or one of those stupid ducks. I wanted to kill the dog but the game wouldn't register that I shot him...

 

[Death on Trapezoids]

I would have to say one of those stupid little annoying hopper things in Jak 1.
Either that, or something in Ty (the Tasmainian Tiger, hurray for Australia!)

EDIT: or from crash bandicoot: the wrath of cortex

 

[Nedoras]

An octorok in The Legend Of Zelda on the Nintendo. First video game i ever played, first enemy I ever killed. Good times.

 

[Tony2077]

damned if i could recall

 

[Cain_Zeros]

The first goomba in Super Mario Bros 3. That began the slaughter of mushroom people.

 

[Xeros]

It was one of those eyes with feet in Mega Man 3. Hold on, let me see if I can find a pic....

EDIT:

Spoiler: Found it

 

[Superior Mind]

Erm, maybe a paratrooper in "Paratrooper". Or a Gruzzle in "Apogee Maths Adventure". I dunno, my folks kept me away from video games as a kid. I do remember my first "modern gaming" kill. I shot my friend in the BF1942 Wake Island demo. I was so astounded by the realness of it all that I thought he was faking so kept unloading until the body faded away. I suppose that's when I popped my gaming-kill cherry so to speak at the ripe old age of 14.

 

[Altorin]

Goomba in Super Mario Bros or a Duck in Duck Hunt

 

[Silva]

A crab robot in Sonic the Hedgehog 1.

A humble beginning.

We went from first game to first game kill? Man that's a little silly, but I'll go with it!

A moto bug!

Haha, that's the one!

 

[magikltrevr]

a goomba little bastards have been my foe since the start

Yup. That. Super Mario Bros was my first game ever.

 

[pyrosaw]

something in star wars battlefront 2.
