This Superman Prime One Million, and immensely powerful Superman variant that sun dipped for 15,000 years when he was put in exile. Besides showing his god like powers off by one-shotting Solaris, and re-creating Krypton and Lois he is practically feat less. However, because of the way that sundipping works we can estimate how powerful this Superman really is. You can do this by using the stats of the pre-52 Superman and multiplying them by how long he Sundips. Superman once sunidpped for 15 minutes, and came out 3 times as powerful.
Assuming that this level of power never decreases or increases you can get vague calculations of how powerful this guy really is. It has been calculated that Superman's standard lifting power should be around 6,600,000,000,000,000,000 Tons (6.6 Quintillion Tons) it is possible that he exceeds this capacity. After Sundipping for 15,000 years, Superman P1M should be able to lift around 10,400,000,000,000,000,000,000,000,000 Ton (10.4 Octillion Tons) once again, it is possible that he exceeds that number As for striking power, it has been calculated that Superman has been able to hit with the force of around 10,000,000,000,000,000,000,000,000,000 (10 Octillion megatons) as far as feats go this seems to be his most powerful strike.
