HL2 Character Names?

[DevgruSeal]

The half-life 2 characters...what are their names...

I know of:
headcrab
zombie
strider

and a couple of others...but i cant remember their names...one is the ones shown in "Bugbait"...and the other is the ppl who would zap into the middle of the game in HL1, who you had to kill (electricity weirdos) who help you this time around in HL2...

What others am I missing?
