#two steps.

Dude was super religious while at the same time basically being in a pissing contest with it.

They gave him the most on the nose lesson on humility possible, and he doubles down on everything in an act of stubbornness that's almost admirable in how awful and stupid it is.

And out of all the BB villains bar Mapleshade, he wins. He is such a fucking menace that he forces his own religion to bribe him and then becomes a patron deity of said religion, and irreversibly changes his entire society for the worse through sheer force of will.

He believes that the world revolves around him and only him, and to be honest, I kinda see why he thinks that

Thistleclaw and Tigerstar wish they were half as successful as Clearsky, and he didn't do it through plotting or magic, but by refusing to learn his god damn lesson no matter how many times it came back to bite him.

I feel like, especially in the Current Day with the Events That Occur around us irl, it's a shame that we never get villains who win through SHEER force of will. It's so, so rare in fiction.

BB!Skystar isn't scheming, he doesn't have a master plan, he doesn't even really have an end goal at the height of his power. He just lives in his own head and does whatever the hell he wants.

That's it! So simple! No self-reflection, absolutely incapable of taking criticism, refuses to grow and change. He has a beautifully simple mind. And it is that very lack of conscious that leads to his strength. You can't shame the shameless. You can't convince him to amend his ways.

There's one way to overcome him; to defeat him, physically. To remove his power. Nothing else will work; he will keep coming back until he is stripped of it. In BB he is the first leader to die, because of that.

Even after Thunderstar refuses to kill a helpless opponent, Skystar took his last chance and went right back to war with it.

And he'll deliver a speech about everyone having one life to give, and about the goodness and righteousness of dying for a cause, but that's all just his rationalization. He can't confront the truth, so he never will. If he did think about it for more than a second... he would be the bad guy.

But he can't. He can't be the bad guy. Because then he would be wrong. So he will simply never think about it.

In the end, what does him in is the fact he got out-bullied by a bigger tyrant. He realized that his power would be threatened by there being less warfare, and he flinched first. His invulnerability was compromised, in that last moment, because it was the ONLY moment where he entertained self-doubt.
