Giants Can Breath In Space

It's common knowledge that Macrophiles and G/T lovers a like blatantly and frequently break the Square Cube Law. It's only natural.
But to some, that's not enough. They want their giants to grow even larger, to basically become gods of planets, to be pure awesome and stuff. Just one problem: Space isn't Breathable, and it's colder than Absolute 0.
Thing is, many G/T and Macro works outright ignore this. Almost to cartoonish degrees. 
As you can guess, this coincides anything involving Larger-than-Planet Giants, or even Giants tall enough to breach the atmosphere.
Giants can also "fly" around space or act as if they are affected by gravity (like the example pic). Expect careless planetary destruction, flying around, and even Galaxy-sized Giants. 
This is the Macro equivalent to Batman Can Breathe in Space
