TOAA.
How is this even being debated? How do you see this battle going? They launch against a long bearded man with a triangle floating over his head like when thanos could apparently be found to be battled even as he was everything including his 'enemies'? (worst writing ever)
It ends before it starts. Thanos never gets the HOTU; the abstracts never come to be; if he wants them to be, they never grow the nerve to raise a hand against him; if he lets (or more to the point makes)
them revolt he swats them like flies unless it suits his own designs.
lols at the idea of 1 month of prep making a difference. Are they going to come up with a secret plan the omniscient won't know about? not to mention TOAA is time itself
The only conceivable menace to TOAA is, depending entirely on your interpretation of marvel's cosmology, the beyond universe where the energy that makes cosmic cubes comes from.
