Death Battle is probably dubbed as the canon/ official internet analysis of battles between fictional characters, I find it very entertaining and backs it's results with a lot of explanations. It's just that in the most recent DB of Goku versus Superman, some comments on the youtube teaser and DB website has raised doubts in me that Boomstick and Wiz (show hosts) may not have calculated Goku's numbers accurately. I know, Goku's numbers are difficult to measure to an accurate state because the show never really introduced numbers to showcase character feats, but when I say inaccurately, I mean completely off. Here's why:
1. GT was used as SSJ4 was introduced. Therefore in this DB, GT is considered canon, apart from Future Goku whose numbers could not be estimated. However we can still measure Base Goku's strength at the beginning of GT.
2. Base GT Goku was toying with Uub, whose power level is the equivalent of Kid Buu. Though Uub was not properly trained for combat, he relied on his anger and instincts in this fight, just like how Kid Buu was in DBZ. Though obviously without the use of Ki, Uub's fighting ability is still below Kid Buu's, however his close combat abilities should be on par with Kid Buu's.
What does this imply? Goku at SSJ3 almost barely kept up with Kid Buu (who was using Ki blasts) in DBZ. So if Base GT Goku could handle Uub in close quarter combat, it implies that his power at the beginning of GT is near SSJ3. Thus using DB's gravity formula, base Goku's ability in Strength output should be at DBZ SSj3 level, which according to Death Battle is 16,000 tons. Which implicates that his maximum Strength potential should be:
16,000 (base) x 50 x 2 x 4 x 10 = 640,000,000 tons
Meaning in the versus Superman DB, his speed calculations were also off, which I'm too lazy to do right now.
3. Back to point 1, since GT Goku and SSj4 is available for judging(apart from Future Shenron Goku), the DB should have scaled Goku's power to the beginning of GT, where he was at his PRIME, before he was turned into a kid and 'powers sent into flux' - Quote by Wiz. In the Death Battle video at approximately 28:16 minutes, Boomstick clearly states they should judge Goku and regular Superman at their primes. At 27:48 Wiz states GT Goku's power levels are terribly inconsistent, and then goes on to say "Due to his untimely transformation into a child." Well, what da ya know? Prime Goku doesn't need to be judged as a chibi, he can be judged at beginning of GT.
Therefore for this particular DB, I'd say the calculations for Goku were disadvantageous because they should have used GT Goku (adult), who was clearly at his prime. Just something I thought to share with the community.
