Why is The Void so different from Loki to Deadpool & Wolverine then even more different in Thunderbolts? Thunderbolts Void is more similar to dark shadowy monsters from Thor 4 and Venom 3. Why no established connection between them?

Different directors

Artistic license

The Void from Thunderbolts is entirely unrelated to the Void from Loki

Why did you bring the Void from Thunderbolts into this?

The Void in Thunderbolts is a person, not a place. They are different things that just happen to share a name. There is 0 connection between them

As for why it looks different between Loki and Deadpool and Wolverine? I don’t know. Different creative teams with different approaches

The void is theoretically infinite. Loki and Deadpool and Wolverine just happen to take place in different parts of it.

Why does the Amazon rainforest different from Siberia? They're both Earth.

It’s Sentry’s void in thunderbolts. Those people are basically trapped inside his mind. In Loki and DP&W they’re in a void at the end of time.

Deadpool & Wolverine end up on a different side of the Void. And The Void from Thunderbolts is an entity unrelated to the TVA’s pruning wasteland.
