My problems with the current feats
Most of the Aliens are low 7-B to 7-A because of Armodrillo and Diamondhead. The low 7-B feat assumes the castle is five square miles and scales to internal damage anyway. As for the 7-A one; although there's nothing wrong with the feat itself, being 7-A after surviving a hit from a high 5-A was always funny to me. It's also not any kind of anti-feat. At best You can argue it's an outlier because of Malgax but I digress. Like I said, there's nothing wrong with it, there's no anti-feat, so we could potentially go higher.
My solution
The feat
A while ago, the low end for
this calculation was accepted by Kep and I think Therefir. I was wrong about what I said before.
Look closely and you'll see that Vilgax actually did manage to put Ben inside his mouth. He also just sits there instead of looking around, like I claimed, which further implies Vilgax succeed at putting Ben in his mouth. If Ben did escape, it would make sense for Vilgax to look around but he didn't.
Another thing; It doesn’t make sense for Ben to blitz Vilgax out of nowhere, considering Ben was in his grasp and the last time Ben tried to escape, Vilgax caught him without much effort. Not to mention, even Jetray couldn’t blitz him like that since they have comparable reactions.
It's very possible that they were still fighting considering
how long it took Ben to get out and Kevin even says Ben is "still stomping out Vilgax."
Ben even says Vilgax survived
worse, so this should indeed scale to Vilgax naturally.
The scaling
Some might think this only scales to AF to UA to OS keys but it should scale to the OS characters as well. We know characters like
Swampfire and Kevin can harm Vilgax and are
comparable to Kraab. The same Kraab who's strong enough to
fight a 10 year old Diamondhead. Aliens like Heatblast and even Stinkly
can slightly harm Four arms,
harm Diamondhead to an extent,
and can even take hits from Vilgax as well as knock him down.
Conclusion
OS mid tiers (EX: Stinklfy, Upchuck) are "at most
low 6-B"
OS high tiers (EX: Diamondhead, Heatblast, Four Arms) are "
low 6-B"
UAFO mid tiers (EX: Big Chill, Kevin, Swampfire) are "
low 6-B"
UFAO high tiers (EX: Humungousaur, Vilgax) are "
low 6-B, likely
higher"
Charcters like Aggregor, U. Humungousaur, U. Echo Echo, and U. Kevin should be 6-B.
