“Unpronounceable”
The symbiotes name is said to be unpronounceable, and this is a fairly common trope in cosmic stuff. Now, when it comes to this trope, a lot of people seem to think that means their true name is some eldritch incantatio, but it just means a human can’t recreate it vocally. For all we know, the black suit’s real name could be a car alarm!
Just wanted to make this point.
