Roshi...?

[Miracles]

What was Jackie Chun's power level ["Battle power"] when he powered himself up to destroy the moon in the 21st tournament? I was wondering was this labeled in any of the guides?

[Ghost of Vegeta]

139 according to this.

[Herms]

Actually no. He only reached 139 after powering up by training for the 22nd Tenkaichi Budoukai. So he was weaker at the 21st, but we don't know by how much.

[Tyro]

Judging by what we're shown, Muten Roshi, Tenshinhan, and Goku ("tournament battle power") are all approximately equal in terms of physical strength and speed.

The same can be said about Muten Roshi and Goku at the 21st Tenkaichi Budokai.

We're shown that Goku goes through some pretty serious training between Budokais; the more major ones being training at Karin-sama's and his solo training for the remainder of the 3 years. I assume both of these events yielded astonishing increases for Goku.

Therefore Muten Roshi must have been significantly weaker at the 21st Tenkaichi Budokai when compared to himself at the 22nd.

[Bussani]

To make things more confusing, Jackie Chun supposedly didn't show his full power at the 22nd tournament. He gave up before doing so, according to Tenshinhan. I guess we don't know whether that battle power takes that into consideration?

[Kaboom]

Isn't 139 just his normal power level? The Kamehameha greatly focuses and amplifies one's strength when performed, so a Full-Power Kamehameha would probably be several times stronger than that, I'd think.

[Herms]

Yeah, 139 is what Bulma's converted scouter read him as when he was just standing around Kame House.

[Piccolo Daimao]

Actually no. He only reached 139 after powering up by training for the 22nd Tenkaichi Budoukai. So he was weaker at the 21st, but we don't know by how much.

I wonder why the staff at Daizenshuu did that. I mean, Roshi clearly had a even match with Tenshinhan, but is supposedly weaker than Tenshinhan because he said he would've lost if they continued the fight. But Tenshinhan says that Roshi didn't show his true strength. Which means 139 is an incorrect level for Roshi at the 22nd Budokai, and, if going by the manga and taking into account the Daizenshuu level for Tenshinhan, Roshi should be between 165 - 180.

I don't know. If Kame-sennin said he would have lost, then it probably means he would have lost even if he showed his true strength. Why would he say he would've lost if it weren't true?

Either the staff didn't look into the fight between Tenshinhan and Muten Roshi well enough, or they were stupid to assume that Roshi stayed at 139 for 8 years without training, and that someone with a power level of 139 can hold his own against someone with a power level of 180. I'm not sure if they thoroughly researched through the whole manga, since they contradict the manga a number of times.

[Herms]

Well, battle powers were never supposed to be some sort of science. Their whole role in the series is to be unreliable when fighting against someone from Earth, after all.

[Tyro]

I don't recall Tenshinhan saying that Muten Roshi didn't use his full strength, but even if he did, that doesn't mean that Muten Roshi was holding back his physical strength. Notice when Tenshinhan says that he'll shown Muten Roshi a preview of his "full power", he uses the Taiyo-ken technique. Muten Roshi could likewise be holding back in the same fashion.

An easy workaround could be that the recorded 139 is not his max (which would then be around 180). Then 8 years later, his unknown max would be lower. In other words:

Pilaf:
Normal strength = 139
(seen) Max strength = 180

22nd Budokai:
Normal strength = 139
(unseen) Max strength = 165-180

Scouter Reading:
Normal strength = 139
(unseen) Max strength = 139-165
