Cracking/Breaking

This article may contain spoilers for TTotM.

Cracking
Cracking is when an alien's form cracks. This mostly happens during wars. When an alien cracks, they forget mostly everything that had ever happened to them. They only remember one thing, and that is what Tribe they belong to and what planet they are from. The first being a cracked alien sees is automatically their leader. For example, the first person Tucker sees (Colin) is automatically his superior. He refers to him as his leader. When an Improver cracks, their role is taken from them. If they want to become an Improver again, they must earn the title again once they remember everything.

Breaking
Breaking is the extreme version of cracking. When someone breaks, they forget everything that has ever happened to them, even where they come from. Their form shatters into dust. It's almost as if they die. When an Improver breaks, their role is taken from them. They cannot earn the title again because they are dead.

Trivia

 * Obviously, Cracking and Breaking is heavily inspired by 'Shattering' in Steven Universe.
 * Although cracking mostly comes from wars, Tucker cracked from crashing in his MTI.
 * One of King Apollo's gills is cracked. Since he doesn't need his gills for anything special, he hasn't forgotten anything. He can also regrow his gills, considering how axolotls can regrow them as well.
