Suicide Squad vs. Defenders+

Maybe I missed it, but when has Luke Cage been shown to be resistant to fire and heat?

In Jessica Jones, when his bar blew up in a big fireball, with him inside.

In Luke Cage, when he took a hit from a rocket launcher which, again, caused a big fireball.

In The Defenders, when Bakuto and Murakami ignite the one gas pipe in order to escape during the one team battle, and Luke walks through the burning gas, puts his hand over the slash in the metal gas pipe, smothering the flame before crushing it closed.

WHile pretty small compared to those, he didn't get any muzzle burns from having a shotgun barrel pressing against his chin when it went off.

Then there is also the acid bath I mentioned earlier, which was heated to several hundred degrees as well IIRC. Every time I can recall Luke encountering heat/fire, he's been fine.
