does it have a weak spot? And can it be tamed??
and (yes this is inspired from analog horror) does it use its past prey as bait? Similar to siren-head, I mean. Like does it imitate the voice of the prey they have killed?
Its interior is fragile, so a missile could very well do the job and it wouldn't be that hard to miss with a mouth like that.
And he just tries to imitate the human sounds and voices he hears, whether it's from prey or survivors. But he's not stupid, if there's a group of people he might try to imitate the voice of one of them to get the attention of the rest.
