It would seem that a lot of morons think I'm bias and that I'm only to DC. Well then to the idiots that think I'm bias go check out my "How Goku vs Superman Rematch Should have ended" story where I explain why Goku would beat Superman but now on to this.
Now as I said before I only used New 52 Superman (or more specifically Superman from "Darkseid War" and "Justice League War" comic) for this battle. This Superman does NOT have infinite power,he DOES have physical limits and IS killable.
Now then, New 52 Superman traveled to the core of of our planet,to see how long he can lift it without getting tired out and Superman lifted the Earth for 5 days with zero exposure to sunlight, he was doing this so casually that the doctors behind the operation wanted to add a wormhole to put him to the test, but they were afraid it would destroy the planet.
At the very least if it took Superman one second to do one raft of lifting the Earth this would mean that at the very least he lifted the Earth adleast 432 thousand times and remember he did this without rest or sunlight. This puts his strength easily at multi-solar system level,the average galaxy has 500 billion stars and planets combined,but the average solar system only has 12 planets. So if we substitute one Earth wrapped with one planet on average Superman has the strength to lift over 36,000 solar systems.
Another important fact is Superman's first battle with Doomsday,in that battle Superman was able to tear Doomsday in half with his bare hands. Now it is important to point out that New 52 Doomsday is NOT the strongest incarnation of Doomsday in the DC Universe,however this version of Doomsday was still designed to defeat New 52 Superman and that version of Doomsday lost.
New 52 Superman can easily survive and escape from a black hole plus traveling for 2 months nonstop into deep space. Escaping and surviving a black hole puts his speed above light and his durability above solar-system level.
As I said before Superman absorbed negative solar energy from the fire-pits of Apocylapse. This new formation makes him: "The God of Steel"
God of Steel Superman is pretty much what he sounds like,he does not hold back his punches and does his best to finish battles as fast as possible. For example God of Steel Superman literally one-shotted a being capable of destroying the whole galaxy,not only did Superman beat him, he one-punched him.
Now onto Broly
Broly has form called the Legendary Super Saiyan form which makes him significantly stronger than any normal Super Saiyan. He can easily destroy planets with simple ki blasts. Over time Broly slowly and surely destroyed the south galaxy,this destruction feat however does not put Broly at galaxy level,simply because this destruction was a SLOW one that ripped the galaxy apart solar system by solar system.
I don't care if anyone says I'm wrong,or if anyone says I'm bias these are the facts and feats that both characters have.
