Because someone's Semblance struck it, whether by accident or not.

This pretty much is based on that Jordan + Monty Oum at Autralia video where they talked about various stuff and such.

So Monty mentioned - whether it's a slip of a tongue, whether it's misdirection, whatever - that a person's spirit has no true limits. He went on to say something like, 'if it happens, it may be able to blow up a small planet... maybe a moon.' So yes, while a Semblance may not be able to destroy an entire planet (he was like yeah it's super powerful but a planet? c'mon), defacing the moon is not impossible.

At the very least, we're going to see power level at that scale sooner or later.

Next, the significance of the moon.

So I'm not sure if someone has already mentioned it, and as usual if you did, come here and leave a reply or link or whatever.

The current standing theory (more like the few moon theories that I remember and didn't completely throw out of the window) is that:

1) The moon symbolizes the amount of Dusts, and it's running out.

2) The moon protects Remnant, and it's slowly crumbling due to evil force.

My idea is pretty simple too. When the moon is full, the Grimm is at their full power and perhaps bloodlust. When it shows its cracked phase, the Grimm's activity is lowered. That's it.

The other more unrealistic theory is that the purpose of Cinder gathering so much Dust is to ultimately reform the moon back into its complete state. Also quite simple.

But possible.
