My vote is monk from age of empires 2. These dudes can walk up and stare at your friend chanting for a bit, then suddenly they turn around and attack you. That’s horrifying.

Basic builder units. You commit genocide against an entire civilization but leave one of these fuckers alive and 20 minutes later you’re facing en entire army.
An ultralisk was the first thing that I thought of.
Dark Templar from StarCraft. Just going about your business then suddenly you’re sliced in half.
A Ghost dropping a nuke is pretty scary but not much different from the real life possibility of dying from a mile you didn’t know was coming. Just not from an invisible person.
Being infested by the zerg would be pretty terrifying too. Not really a specific unit though, I don’t think. Haven’t played in quite a while.
An engineer from C&C. They just enter any of your buildings and poof, it’s theirs now.
The freaking Deviator the Ordos had in Dune II.
It turns your units against you. Sure the ROF is low, but damn. Plus, given how the controls worked (or didn’t) back in the days, this caused utter havoc not only with the unit control but also other unit’s pathing.
Something in 40k universe probably. Tyranid or demon units would probably be my top choice for worst. Necrons are literal terminators too.
It depends. AoE2 Organ Guns, in a group of at least 10, will obliterate basically everything in their path, but alone theyre not too menacing to anything other than vils.
Any Scrin unit from C&C Tiberium Wars, because that faction was overpowered.
Merkava IIIB in wargame red dragon, that or the SU-27M. nightmare fuel
Siege tanks in siege mode
