I see that 10 rating with basically no other info on a crit success this way.
Imagine it this way, you are The Guild of Calmitous intent, you are THE Supervillain guild. You are old, respected, Supervillains come to you. You set the rules, you dictate how things are done. You're full of great powers united yet bickering as Supervillains do.
Then one day you find out that a Supervillain exists you weren't aware of. Naturally that's understandable, no one's perfect. But he's not just a Supervillain, he's a mastermind type with an entire group behind them. Anti-kid but still, a large group. And it turns out there was a large child hero secret agent group you also weren't aware of that they had been fighting.
Or maybe you were aware of them but simply ignored them both for their kid focus and seeming lack of lethality. Someone off in their own sandbox with a child organization, facing off against one another keeping both in check, unrelated to your own business.
Suddenly one day you're very much aware of this Supervillain, or at least they're suddenly big news. Going from fighting children to devastating an invading alien army alongside the Military.
With either some digging, or knowing them already, you with your secretive intelligence gathering network and supervillains of all kinds, could easily know one thing, that this is a serious deviation from what they were doing before a sudden months long silence.
Maybe you find out more even, about what happened, maybe you don't, maybe you find out about how their nemesis organization crumbled and is left headless and weak. You could probably easily notice that they're not focusing on destroying the last remnants of it though.
Regardless, this anti-kid villain is suddenly fighting alongside the government, due to not having an official supervillain rating. Suddenly smashing up an army. Perhaps it was just a show of power, an easy way to display that they're not to be messed with, but they kept at it. And fought one of the big names of the enemy force, taking them out for a time in a way so impressive the government was compelled to turn his exploits into propaganda with only the barest trace of plausible deniability as to the subject of the propaganda to prevent people from accusing them of glorifying a supervillain.
Now you can't ignore this guy anymore. You have to address them somehow. Not just for your own internal reasons or for public credibility, but to appease his supervillain ego so you don't start a fight.
Naturally with someone so powerful, with a history of supervillainy, he's a shoo-in for a 10 Supervillain! Right? Get him in, go through everything, right?
Except, he's working with the government, who is willing to work with him because he's not officially a supervillain. And he's doing some good work, being idolized in propaganda, surely that's heroic stuff. And he's being backed by Monstroso, who is 'mostly legitimate', a sign of what he's pursuing perhaps?
Maybe in that months long silence he's decided to turn over a new leaf. Or maybe he's a bit unstable and doing good as well as bad. Or who knows his plans?
So, Superhero 10? Except you really can't do that, just for some incidental heroism! At least not to a villain that powerful and potentially mentally unstable from what you've seen of his actions and change in them and if you dig further the obvious trauma of what he's been through. The guy if he still thinks of himself as a Supervillain would likely take offense, and for someone powered by his anger, that's a bad thing to do without being prepared for it.
But, you need to rate him, you can't just ignore him. So, considering his potential of going for 'Villain with good publicity' and the problems from rating him Hero or Villain, you just give him his rating. The strongest allowed by you. Ten. Without further detail.
The ball's in his court now if he wants to clarify that further. You did your job of rating his power, showing him the respect he's earned and sealing off the low levels from starting a fight with someone like that, at least without you being able to declare they ignored protocol and whatnot and offer them up as sacrifice.
Now Father has been poked and appeased as your pride allows, up to him if he wants to pursue it further and receive your services.
