Ah, yeah, Venom is just a suit in the same way that a TARDIS is just a box, heh.
IIRC, isn’t it that you don’t actually wear a symobiote as much as it kinda completely absorbs you? Sort of like … After a caterpillar goes inside a cocoon, it … Dissolves. Into caterpillar goop. And then the goop reforms into a butterfly.
In the limited series from the 90s, Venom: Carnage Unleashed, Venom is thrown in to a train by carnage and merges in to a stripe on the train to hide and escape.
I mean Venom is injured all the time in ways that would clearly impact a body within it. So either the host body goes full caterpillar-coccoon and is basically jelly while Venom is fully formed, or the host’s body becomes immune to injury/near fully regenerable, in which case Venom could wreck the host’s face without worry.
