How Much Power Did Vegeta Lose In The Saiyan Arc?

[theherodjl]

When Vegeta shot up to his full BP of 18,000 against Goku and then took various forms of damage after being hit by the KKx3 as well as generating a mini-blutz moon, how much power did he drop? Also after taking some damage while in Oozaru and getting his tail cut off, where did Vegeta stand then?
For an angry Gohan to be able to combat a weary and injured Vegeta it would have to mean that his BP was not a great deal higher than 2,800, does that mean Vegeta lost as much as 16,000 points of BP after all that damage & usage of power?

[Kaboom]

No real way to tell. All we know is that it's below his full power, and more than Goku could handle even with a Kaio-Ken x5 by his own admission. So somewhere between 40,000 and 180,000.

I like to think a kaioken x6 would fill the gap between them or possibly surpass Vegeta. So, his Oozaru form should have a powerlevel or 45,000. Having lost his tail made Vegeta much weaker, but with a powerlevel or 4,500 he could still handle Gohan.

After getting beaten severely by Kaioken x3 Goku and putting all his power into the failed Galick Gun, Vegeta already should have lost some strength even before generating the fake moon. Nothing beyond standard battle fatigue, but probably something to consider. If his max is 18,000, I'll say he was at 16,000, that gut punch from Goku was savage, and the Galick Gun had to have taken a decent toll.

Next he creates the fake moon, and Vegeta specifically states that it takes away some power. The fact that it was enough power for him to specifically note it indicates to me that the amount is substantial. 4,000 sounds like a good number, and it explains why creating a fake moon wasn't the go-to tactic for lesser Saiyans, as they would be very drained and transforming wouldn't have made much of a difference. Then the act of transforming itself, plus having his tail chopped off and forcibly regressing should have taken a toll too. By the end of it, I'll say he was as low as 10,000.

Gohan's pep talk from Goku and subsequent conviction definitely contributed to his doing so well against Vegeta, but he was ultimately outmatched anyway, so I don't see a problem there.

Actually now that I think about it, I'm wrong. The power depletion would have had to be much more up to this point, as Vegeta would need to be below 400 in order to get crushed by Oozaru Gohan considering Goku at the 23ed Budokai easily handled the weight of a similarly large Piccolo, and as strong as the Spirit Bomb was I don't think it would have chopped off that much power alone. Okay let's retry this;

-Full strength = 18,000
-Battle with Goku = 16,000
-Creating the fake moon = 8,000 (let's say it cuts the Saiyan's power in half, that makes a lot of sense to me)
-Transforming and then regressing + Goku shooting his eye = 4,500
-The Spirit Bomb = 500
-Yajirobe's deep cut across his back + total fatigue = 400
-Crushed by Gohan = 1 (near death)

[ZombieVito]

He can't be at 500 after the Genkidama. He easily beat Yajirobe who is at 970.

I have him at 4,000 after his Oozaru transformation and 1,500 after the Genkidama.

[DanielSSJ]

This is what I have.
full powe - 18,000
after taking a x4 Kamehameha to the face - 9,000
after creating fake moon - 6,000
Ozaru - 60,000
after taking a Genki Dama from behind - 1,000
after getting sat on by Ozaru Gohan - 20

IMO,after he got blasted,id say his power dropped to 8-9 k,after which id say 4 k or so or maybe less.Making it oozaru being at 35+ k.
