idk if this has been reposted before but megatron at peak power one shotting entire autobot fortresses is almost certainly above baseline city level, accounting for the durability of cybertronian metal as well as the difference in size between a human stronghold and one designed for transformers
thats not even getting into what i believe to be one of the most insane feats of all that gets overlooked
bear with me im about to do MATH
when the war starts in the original TF comics, the Decepticons attack all at once with such devastating power that they not only kill BILLIONS of Autobots, but they derail Cybertron out of orbit, and send it hurtling through space
Cybertron is a massive planet, said to be the size of saturn, and we know the distance from alpha centauri to earth, as well as the time it took to cross that distance, 1,000 years
4 light years = 2.35145e+13 miles
its moving 2,684,303.6 miles per hour, a
planet depending on the mass of cybertron, the energy to move it this fast is insane, so for a lowball i'll use earth mass vs the mass of saturn, since humans can walk on the surface, but cybertron probably isnt the density of a gas giant, idk which is more accurate so dont take any of this as gospel
Earth mass: 4.3026562125761E+36 J
Saturn mass: 4.0918361380104E+38 J
so i guess this is what the Decepticons were capable of as an entire army at the beginning of the war, they could get considerably more powerful than this
also potentially of note i think is using this velocity, i was able to find that cybertron has travelled 16,000 light years in the past four million years, and would be 15,996 light years from earth, at least in the comics continuity
