Power and ability
Very skilled sorcery on par with Thor's strength with the hammer and very smart to manipulate Odin and his sorcery also mind beat odin who could mind fight Galactus and being able to shapshiffe into any form and takes it traits such as biology and gender which is why he has a snake and a horse as children
Such bluster. How very typical. Ever the sheltered son. So many fractured delusions. You know nothing of war. For all these countless millennia -- when it comes to the two of us -- you seem to have avoided the simplest of conclusions. Instead, you feel the incessant need to avenge every wrong you perceive from your position of languid morality...as if it were some sort of game. Quite sad. But if it's a war you truly desire, Thor -- then Loki can happily provide.
