Thanos & Darksied vs The Kryptonian

The Kryptonian is the most powerful of Galactus's heralds. Superman's power is combined with Galactus's gift of the Power Cosmic to make one of the most powerful Superman ever.

i'd say the kryptonian would be oblivous to the fact that somebody was trying to attack him until they were actually on the battlefield...

which means thanos and darkseid get prep time. which means this could actually be a mismatch for the kryptonian despite the power edge he may hold.

Thanos is the best prep. of marvel and DS is the biggest troller ever. They can take out Kryptonian.
