Why do Moon busting/creation feats typically come out as 5-B/A?

[Megavert56]

Examples being fairy tail, Thanos moon ripping feat, piccolo moon vaporization etc

Good old kinetic energy and GBE enlargement shenanigans.

Piccolo's case is 5-A only in Toei tho, not in the manga. Standard vaporization of the moon is just baseline 5-C.

 

[Psychomaster35]

Creating the moon is still 5-C assuming it’s done through energy/hax and not moving parts around.

But if the parts of the moon are moving around as it’s being created/destroyed, KE regularly gets that to 5-B or 5-A.

Basically what the others said. GBE is simply a baseline, but if someone does a feat with ease and basically overkills the moon, it can result in kinetic energy yields much higher than the standard Moon level. The highest Moon busting feat I have seen was like High 5-A. It's similar to how busting the Earth could go up to Low 4-C or how Chase Young has a High 4-C key via a calculation that involves destroying Jupiter.

Kinetic energy

Let's say the fragments of the moon reaching at a speed somewhat close to the speed of light often yield or requires higher force to achieve

thus destroying a moon and causing it to scatter across space or having its fragment reach Earth in quick timeframes often inflates it logically (and fiction somehow doesn't considers this when showcasing such feat)

What's funny is the opposite is usually true for mountain busting feats.

hehe yeah, though that might be on us since the mountain tier is arbitrary
