I wrote an little essay about Beerus Power recently. I know it's kind of long, but I put a lot of work into this. I'll be grateful for everyone, who reads it. I would like if you shared your thoughts, gave your opinion and came up with new ideas. If you are no nerdy fan boy like me, this may shock you. If you are, you might be pretty astounded.
Let's face some facts:
1. Age and Lifespan
Beerus is something between 200 million and 1 billion years old. The average lifetime of humans and Saiyans is 80 years, maybe 100, under good conditions. Guru was 500 when he died. So Beerus has been living an equivalent of 10 million human or 2 million Namekian lifetimes. Imagine you had lived 10.000.000 lifetimes in just one life. Thats so ridiculously long, our brains aren't capable of understanding what this is actually like.
If Beerus spent 90% of his time sleeping, 5% with eating, 4% with annoying Whis and 1% with training/fighting/destroying, that'll translate to (remember RoSaTs), 10 million years. Btw 1% of a day are just 14,4 minutes.
Imagine living 100 times for 100 years. In this time, you do NOTHING but training non-stop. No eating, not sleeping, no nothing, just working out. It's hard for a human beeing to imagine but possible. And that's JUST 0.1% of the time Beerus did!
2. The ridiculous Growth in power over time
DB characters grow when they fight/train. The anime and manga heavingly imply, that there's no power cap. And Well, I did the math.
VASTLY LOWBALLED: Let's give Beerus a base power of 1 in the beginning and assume he becomes 10% stronger every 10 years, just counting those, in which he acutally has been working out (that beeing 10 million years, when assuming 1% lof his lifetime spent with training). Next to some kind of asspulls, that's how it works in DB. You train or fight -> you grow.
[Note: Goku, Vegeta and even Krilllin grow at an vastly faster pace in canon, the assumed growth rate is a massive lowball]
Beerus Power(level) would therefore be: = 1.1^10,000,000 = 1.1^(10^7) ~ 1.1^(3,162^2) ~ 10^413,927. That's freaking huge number. To give you an Idea, the amount of digits of this number listed in a word document with calibri 11 and no space holders covers over 133 pages. And it's likley he actually grows much faster than this, which would drawf the power estimation of 7.11x10^413,926 by such a wide margin, it might be very hard to even calculate or properly write it down.
You could lowball it even more, e. G. putting Beerus power at "just" 10^240.000. This is literally nothing in comparision to the first lowball, but it is still a giant amount and unbeatable as it is unreachable for mortlas.
3. Example: Comparsion to a very Highballed strength gain of a mortal
Let's calculate the power of a prodigy mortal vastly HIGHBALLED:
Assume this mortal had a lifespan of 100 years and let's ignore the fact his strength likely decays when he grows old. Furthermore his strength 10.000folds every year, which is just an INSANE rate of growth. If it the power was 1 in the beginning aswell, after 100 years it will therefore be:
10,000^100 = (100^100)^2 = [(10^2)^(10^2)]^2 = [(10^2)^100]^2 = (10^2)^200 =10^400.
Even than if we went with Beerus second lowball, when in comparision the power of this mortal was the size of an atom, the size of Beerus Power would be many many many orders of magnitudes bigger than the observable universe. To compare: There are 10^80 atoms in the universe. Replace every atom in the observable universe with the mortals power estimation value of 10^400. For every single atom there once were replace it with 10^400 atoms. Then replace for every single atom in this new universe the number of the power points of our mortal again. Repeat this 600(!)times. This amount of power would be the same as the lowerballed Power of Beerus. THAT IS JUST FREAKING CRAZY.
I want to remind you HEAVINGLY WE lowballed Beerus twice and also EXTREMLY highballed the mortal.
Words fail to describe the diffrence.
If it happens that Beerus doesn't train/fight/destroy for a 1,000 years, in comparision between a human life and his lifetime, this timespan is just a couple days. Because of his GoD powers I think he wouldn't lose any accumulated strength, even if he slacked of training. No mortal can ever reach him. Beerus true full power is so ridiculously huge, it's incomprehensible.
4. Techniques & Transformations & Powers
We have seen a small amount of examples of what Beerus can do. Don't be surprised if he has like a 100 stackable transformations with which he could tetrate his power to even crazier ammounts and has 1,000S of techniques we don't know of in his arsenal. Just for some examples: He's able to convert energy, KI and even matter. His speed is, besides Whis, the fastest. As a immortal GoD I assume he's able to heal himself pretty quickly, also during battle.
The Overkill might be that our favorite cat always uses UE. -> Grows stronger with every little scratch he takes.
And remeber: He was the one who took on all the other gods during the pre TOP arc at once using UI. He was the last one standing besides Tequilla and would had wiped them out if he hadn't been stopped. Concluding Beerus is able to combine UE & UI, which is just over op. If he can't dodge and is hit, his power grows until it's so high his UI overpowers the enemy.
Besides the GoD 7 vs 1, it's very unlikely for Beerus to be in this situation, unless he simply doesn't use UI.
Shortcut: Beerus power keeps raising during battle to the point where it's simply higher than the power of his opponents. This situation is just hypothetical because it actually can't happen, due to him beeing the strongest beeing besides the Angels, the GP & Zeno.
5. The Definition of a GoD
GoDs are GoDs for are reason. They must sustain the balance between creation and destruction and protect their universe. Therefore they have to be able to deal with every potential threat. So GoDS must be stronger than any other beeing besides the Angels, which indicates every GoD is at the very least the strongest in their respective universe. More likely they are stronger than any mortal, regardless the universe. They supposed to be and are.
If somebody says that Jiren is stronger than Belmond, well yes, he might be (I am really unconvinced he actually is) But only when Belmond is in base. Belmond may have dozens of stackable transformations and 100s of techniques as well. As soon as he transforms or uses a fancy GoD techniques, he swatts Jiren of like a fly.
If they weren't the strongest, their definition would be obsolete. Otherwise the whole system would make no sense at all. At this point: Frieza could be Rainbow Frieza. Beerus literally could kill him by farting.
6. The SSJG Dream
Beerus dreams about fighting. Due to the SSJG dream, it might be possible that he even grows stronger while sleeping. We've already seen this with many other chars in meditation. As Beerus is sleeping most of the time, he probably constantly keeps becoming stronger through that. Not to mention he also is training aswell, which proofs the 1% and above rule.
7. The authors & Beerus statements
"Beerus has the highest degree in battle power." No other words needed here.
"At this rate you will need millions of years to be considered as a worthy rival." He showed the Prince who's boss.
"My power is boundless." -> Indicates Beerus Power might not even be finite. It Could be infinite. It would actually not shock me if it his strength is infinite. At least very close too. The angel tier would have bigger infinities in power than.
If somebody claims to truely understand the extent of the strength of Beerus, he'll most likely doesn't. Our brains can't grasp this. His power are like broken broken. Beyond broken.
And don't you dare even trying to think about Whis' full power. Beware, your head might explode.
8. Fighting off Gag Characters and erasing Ghosts
Gag characters are unkillable, thats their gimmig, as ghosts are ineraseable in mangas. However we saw Beerus beeing able to do the former and actually do the latter. He's so strong he can literally break the rules. It's insane if you think about it.
CONCLUSION
Just for fun I calculated the ammount of power Beerus has if it doubeld every year of his lifetime. It could be a reasonable growth rate.
2^1.000.000.000 = 2^(10^9) = [2^(10×(3^2))] ~ 4.61 × 10^301.029.995.
This number is 300 million digits long. It would cover over 648.850 pages. And this, is just his Base alone. We did not inclcude the stackable 100s of transformations and 1000s of techniques he has got. So even this calculation falls vastly short, when we want to determine his Fullpower.
I doubt that humans have the capacity to grasp the meaning of such crazy numbers. I also doubt that there is enough computing power to write it down and even if it was, I assume even hyperoperators like tetration, pentation and so on could us any idea. Or even be written without the universe collapsing.
NO mortal stands a chance against Beerus. Far, Far from even close, not at all. All the super strong mortals could stack to one entity via potarafusion, use UE and UI at the same time, stack LSSJ Blue 4 with 1,000× Kaioken on top, it wouldn’t matter.
Beerus eats them alive with ease and there are no exceptions. He just can't erase/kill immortals, but is, as far as I know, immortal himself and has other ways to deal with these. Beerus only weaknesses are the death/vulnerability of Shin, who he could simply seal away, protect or possibly even merge with, gaining more power, maybe the power of the Super DragonBalls, but certainly Beerus is overpowered by the angels, the GP and Zeno.
Thank you for your priceless attention!
