There's a huge plot hole within the MCU with Ant Man.
Ant Man can shrink... and he can also grow into the superhero called Goliath.
Thing is... and this is explained in the movies... his actual mass doesn't change.
No change in mass, means no change in weight.
We often see him on the back of an ant... or on a group of ants being helped... yet, even though he's the size of an ant, he still weighs what, 13 stone? About 82kg?
So the fight between him and the bad guy in the first Ant Man movie... has the two of them on a child's table with a Thomas train set...
Even being the size of insects, the table would collapse under their collective weight.
And when the Thomas train gets enlarged, it crashes through the wall and into the street.
Wouldn't happen. The toy may be huge, but it'd still weigh the same as it did when it was regular size... and would just bounce off the wall.
So, another example of this plot hole, is in Civil War.
He flips Black Widow over, grabs her wrist, and runs up her back, pulling her arm up her back.
Thing is, being that small, weighing 13st... he would simply push through Black Widow's body.
Imagine placing a knitting needle on someone's back, and standing on it.
Exact same thing.
As Goliath in Endgame as well... sure he's 100ft tall or whatever... he'd still only weigh 13st.
So punching the Chituari Leviathan, would do nothing.
He also wouldn't be able to push against the mass of rubble that had collapsed on top of him, Rhodes, Hulk and Rocket.
