I've been intending to release an analysis of the holes in the Screw-Attack pitting Superman up against Goku. I re-watched Screw-Attack's Superman vs Goku Death Battle just to double-check for any other screw-ups. I found three more that had gotten past me the first time.
The most important flaw I found was them stating that Superman can survive the impact of multiple supernovas. Uh, hello, Superman's power comes from suns people! As supernovas are the greatest form of energy a sun would release, Superman would be absorbing the energy of the supernova! Of the other two things that I picked up happened in the battle itself involves the Power Pole. Regardless of the validity of an adult Goku using the Power Pole in the first place, I feel that the impact of the attacks were far less effective than they should have been. As Screw-Attack stated, Superman has no resistance to magic. Correct me if I'm wrong, but no resistance means that he would only be as strong as a really strong human, right? Now, let's factor in that Screw-Attack noted that Goku is able to lift 40 tons without ki. Now factor in that Goku was Super Saiyan while he was clobbering Superman, making him capable of lifting 2000 tons. But let's just say that the Power Pole was pummeling Superman with 50 tons of force (2.5% of SS(J) Goku's strength via Screw-Attack's "Gravity Formula")
per hit for the sake of giving a reasonable estimate. Now, since Superman has no resistance to magic, wouldn't 50 tons be enough to break something? To hammer home the point, consider the moment when Superman was trying to get to the sun when Goku Instant Transmitted ahead, smashing Superman who seemed to have been traveling at considerable speed. For the sake of an estimate that is low for the purpose of getting people to agree to it, let us say that Superman was hit by the Power Pole going 340.29 meters/sec (speed of sound at sea level). The equivalent weight of the hit being 50 tons, or 45360 kg. Now that the units are metric, let's calculate the amount of magical newtons the Man of Steel was hit with. The result comes out at 1543555.44 newtons. To put things in perspective, the atomic bomb dropped on Hiroshima was only around 300,000 newtons. Given that this calculation purposefully underestimates the force applied
, we can safely assume that Superman was hit with far more than 5 times the force of an atomic bomb by the Power Pole, a magical object, of which Superman has no inherent resistance against.
The only way I see Superman winning is with his Infinite Mass Punch, as Screw-Attack showed him doing. The problem with this though is, as Screw-Attack shows, Infinite Mass Punch would destroy the Earth, something that Superman wouldn't be willing to do. ScrewAttack factored in how Goku didn't want to fight Superman when he was weakened by Kryptonite. So then where do they get off with making Superman to against everything he stands for and destroying his adopted home planet?!
Still to come in this rant: Why Goku would have figured out Superman's power comes from the sun, Power Levels, and more.
