Weaknesses

In the end, just like any comic book character, the Symbiote also has weaknesses that should be explored in the movie. Spider-Man 3 revealed he’s sensitive to loud noises and sonic waves, which he discovers as he climbs a bell tower.

The Symbiote also fears fire, since his amorphous form collapses if overheated.

But there is one other fear we should explore. The Symbiote fears drifting away in the vacuum of space without a host to feed upon. This is a psychological fear that leads to separation anxiety, and it could cause audiences to further empathize with Venom.
