[DC] Can Superman's heat vision cut through anything? If not, what can't it cut through?
gpt
Depends on how much power he puts into it.

Some materials are totally immune to heat, either as a result of advanced science or magical properties. Some materials - including other Kryptonians - aren't *totally* immune, but are so incredibly durable that he's not able to cut through in a reasonable timeframe, even at full power. Some objects are simply so massive that his heat vision has little effect (for example, he probably can't cut a planet into two pieces with heat vision alone.)
