@Cal, that is not true. Vegeta has his own feat that's well above
Relativistic in Android saga, and his attack speed scales to his combat speed. His Final Flash
destroyed a far away planet. Dodging Death Beams at point blank range also count as an
FTL feat. And also pretty Cell's Solar Kamahameha would also be a back up for the speeds given he nukes the entire solar system. Also, we actually did accept a 10x multiplier for Ichigo and Kenpachi. And Star Wars was given an accepted 1000x multiplier for a certain light-saber crystal.
And side note, even Kid Goku has an
FTL feat; it's a massive outlier much as early series Hiei's
FTL feat, but it still exists.
And I work on the explanation blog today.
