Goku stats
Strength
Teen goku lifted giant picollo in the manga who was easily the size of a sky scraper and bigger than gamabunta
now according to someone
this is gamabunta weight
Gamabunta weighs over 3,050,415 pounds. That means that Gamabunta weighs over 1,525.2 TONS!(although this is wrong more on this later)
So giant picollo weight near 2,000 tons
Goku is base can lift 2000 tons back in dragonball as a teen
and goku base form strength increases throughout the series
multiple by 50 for super saiyan, 2 for supersaiyan 2 and 4 for super saiyan 3, wont use 4 or god mode
Super saiyan: 100,000 tons
Super saiyan 2: 200,000 tons
Super saiyan 3: 800,000 tons
At this point goku is already stronger than naruto in lifting
but wait this is based on goku base form back in dragonball
skip to end of dbz and goku base form is much stronger enough to keep up with uub who took on super saiyan 3 goku
Le Gasp!
which means we have to take super saiyan 3 800,000 tons as goku base form strength and then multiple again!
and that doesnt account for how many times goku base form has increased
in short goku in base form can easily life a million tons
Now to back to 40 tons argument used by downplayers, goku was not using ki when he did that and that means it was just his muscles doing that and we dont know the gravity in the other world
king kai planet had ten times gravity of earth, the grand kai planet is where the strongest fighters in the universe gather would assume to have greater gravity than king kai planet
that could easily make 40 tons 4000 or 400,000 tons, we dont know other than fairy tail dragonslayer assumption just like everything he writes
Also goku was shadow boxing which is not related to lifting strength, he was in the air, trunks lowered his power level to 5
Goku can do the same just to test his muscles
what we do know
Goku's lifting feat
tossing the Kachin cube; we know it's heavier and denser than anything on the earth; the heaviest and densest metals on earth are Iridium on Osmium;
the Kachin is clearly taller than Goku, who is just under 6'.
A cube based on those measurements, made of Osmium would weigh
(5*5*5)(1345)=168125/2
84062.5 Tons.
Another reason base goku can lift more than 40 tons
More over lifting strength does not equal striking strength
Force=massx acceleration
Goku can hurt planet busters like frieza who can survive planet explosions with his punches
Dbz characters control there power not to destroy stuff
Naruto stats
Naruto (Regular Sage Mode): 203,280 Tons (Minimum) although not correct but let just use this
Goku(base form end of dbz):800,000 tons(Minimum) realize this is based on dragonball teen goku not end of dbz goku, so goku is severly under powered here
Naruto vs Goku - arm wrestling match
"Are you sure about this naruto, I wouldnt want to hurt you" said goku
"I believe it, just like I will become hokage one day" said naruto with a smile, goku smiled back
"Alright then, do your best" goku said
"Dweeb you have no chance look at his muscular arm vs your puny arm with no muscles" said sasuke
"Let the match, begin" announced tsunade, the winner becomes hokage for a day
Naruto went straight into sage mode, goku stayed in base form
Naruto started to apply pressure and his face turned red, he closed his eyes. Goku on the other hand was calm not feeling a thing, his arm didnt even budget. "Naruto im we can start" goku said. Naruto opened his eyes, "he must he joking I am giving it everything I got"
"Comeone you can apply pressure now" goku said. Naruto face was full sweat and went red again only after 30 seconds. Goku realized naruto was giving his all and didnt want to embarrass him further. Goku swiftly smacked hand on the table ended naruto effort.
"Sorry naruto, just train a bit more and you beat me next time" goku said trying to be nice, in his head knowing this ninja would never be able to reach his level.
"Thanks for the match goku, naruto grabbed his sore hand in pain"
"Goku is the winner and gets to be hokage for the day" announced tsunade
"well lets eat everyone" goku said
finish
