Mangog is a beast! The very outcome I predicted played out this year in Thor #703!

Mangog tells us over and over again with every other breath, he has the combined strength (but I doubt intellectual power LOL) of one billion, billion beings of a war-like race destroyed by Odin.
Now think about a billion. If you began to count right now and continued 24 hours a day, 7 days a week without a break and averaged counting one numeral per second, it would take about 32 years for you to count to a billion and 32,000 years to count to a trillion.
Now a billion, billion is one million times greater than a trillion! BIG NUMBERS! I really doubt the authors of Mangog’s description took them into account. Too late now though; it’s out there.
A billion, billion is 1 X 10^18 , that's 1,000,000,000,000,000,000!!!
Now let us assume that each member of this war-like race (every man, woman, and child) could lift an average of 50 lbs over his/her head (a conservative figure for a war-like race I think), that's 1 X 10^18 X 50 = 5 X 10^19 pounds! Now divide that by 2000 lbs/ton and you get 2.5 X 10^16 tons!!!
So Mangog could lift at least 2.5 X 10^16 tons = 25,000,000,000,000,000 Tons over his head!
NOW how does that compare with Odin's and Thor's 100 Tons?
Well, 2.5 X 10^16 divided by 100 = 2.5 X 10^14 times stronger!!!
That means that Mangog is 250,000,000,000,000 (that’s 250 trillion - it would take you 32,000 years to count to just ONE trillion!
Mangog has power other than physical as well here, cut and pasted from Marvel:
• Superhuman Strength: Mangog possess vast superhuman strength, the sum totality of a billion billion beings. His physical strength easily by far exceeds that of Thor. Hence, he is far above the class 100 level.
• Superhuman Speed: In spite of his great height and body mass, Mangog is capable of running and moving at speeds that are beyond the physical limits of the finest human athlete.
• Superhuman Stamina: Mangog's advanced musculature produces no fatigue toxins during physical activity. As a result, as long as he is able to psychically feed off the energy manifested by vengeful thoughts, he possesses an limitless physical stamina.
• Superhuman Durability: Mangog's body is far harder and more durable than the body of an Asgardian God. His body is highly resistant to all forms of conventional injury. He can withstand powerful impact forces, exposure to extremes of both temperature and pressure, falls from tremendous heights, and tremendously powerful energy blasts without sustaining injury.
• Superhuman Agility: Mangog's agility, balance, and bodily coordination are all enhanced to levels that are beyond the natural physical limits of even the finest human athlete.
• Superhuman Reflexes: Mangog's reflexes are similarly enhanced and are superior to those of the finest human athlete.
• Energy Manipulation: Mangog is able to manipulate vast amounts of mystical energy for numerous purposes. Though they're used almost always for destructive purposes, the most commonly seen of these include the ability to manipulate most substances on a molecular level and to fire massively powerful blasts of concussive force from his hands. His capacity for energy is so great he swallowed Volstagg's lightning whole before discharging it back with greater force.
• Sin Empowerment: Mangog's greatest strength however lies in his unstoppable rage and malice, coupled with his ability to feed into the anger of others as well as the particular vices of deities to become all the more powerful. Able to absorb and metabolize the hatred of a billion billion beings that he was originally comprised of, to swelling with power whenever a god acted meanly or selfishly and abused their power for petty reasons.
