Could SuperCat defeat Atomic Mouse? These are the questions that never tasked the minds of children in the 50s. I doubt any one cared about the relative strengths and endowments of either, especially when you could argue about whether the Flash could beat Superman in a footrace.
From this illustration it seems that SuperCat is huge. He appears to be stopping a missile from hitting the self-aware, emotionally unsettled nuclear-furnace hanging in space. Perhaps the missile was intended to blow up the sun. Perhaps it was full of small creatures, and the sun was dismayed that certain death awaited its occupants. Neither explains why the sun is sweating.
Or why space is green.
