Ssj2 Kelfa vs vegito is not close (in the anime)
Ssj2 kelfa: kelfa at ssj was stated to be as powerful as super sayain blue x20 Goku and jiren suppressed power. Stated by whis.
(Also Goku was at kaiokenx2 when fighting ssj kelfa. doesn’t change that she’s still ssbkaioken x20 level)
Kelfa was stated to be on ultra instinct omen 2 level stated by whis or Valdos. (Yes ultra instinct is a power up but adds something more to it. and Goku gets stronger every time he gets ultra instinct)
Master Roshi also says that if goku gets hit with one of kelfa laser it’s the end for him which can mean death or knock out (which knock out makes more sense.) And don’t say he was tired because that still doesn’t change the fact that kelfa is still as strong as ultra instinct, omen two. (Or more powerful in terms of raw power.)
And to be clear Goku is more powerful than his first ultra instinct. Want me to tell you why?
If you look at the first time, Goku and Jiren fight Goku use kaioken times 20 and Goku got destroyed. but when he kaioken x20 against him later on he was putting up much more of a better fight against him than the first time they fight. Vegeta said that sayains breakthrough their limits under 48 minutes.
Another example is when Goku use ultra instinct for the first time he was not learning that much on jiren. But with ultra instinct three when he gut punch jiren, jiren Got to hold his stomach for a little bit and cough out spit. That shows you that Goku is getting stronger in the tournament.
In the anime kelfa destroys everybody except for (ultra instinct 3 Goku and jiren)
(In the magna vegtio destroys her)
