Favorite Fallout 3 baddie

[hippo24]

Nuka-Mirelurks, and Mirelurk guards. Its a great deal of fun to be pitted against a giant blue crab, and have to hop around trying desperately to catch a glimpse of his face. I just felt it was satisfying on my first few encounters to be presented with a fun challenge, and then promptly devour his claws shortly after.

Loved those people, they were so creepy!
Person: Please, stay for dinner
Me: Uh...no thanks

I'm a big fan of the queen fire ant... Such a pain to kill with melee due to sheer time spent on it... Ha

Those giant rabid bear-things... I think they're called Yao-gai or something.

They scare the brain out of me.

When I encounter a behemoth, I get all excited. =D

Super mutants!

It's so fun to sneak around them and eavesdrop on conversations like this one I heard in Vault 87:
'I wish I was strong enough to use a power-sledge like the brutes.'
'Yes, so much smash!' (and then he just kinda went 'mmmmmm')

After listening in it's always great to get a sneak headshot with my trusty hunting rifle, most satisfying dismemberment in any game ever.
