Okay. Went through that Google Sheets of logs, some things I noticed:
Things we can eliminate
There is at least 1 unlock with Tachyon and Bunker incaped (i believe that is what n/a means on that sheet.
Several logs without AZ doing the last hit.
Progeny Flipped and didnt flip in unlocks, as well as ended on both his front and his back
There are 3 games that report no Scion of Frost being played.
There is one game where Null-Point wasn't even played (- However it did ENTER play, probably through someone's shenangins)
There are games without all one shots having been played (so playing all of them is not a requirement)
There are games where Ongoing powers are not used.
There are games where Thermodynamics does not initiate cold or does not initiate fire.
The Lowest Cold Damage done to self was 29.
The lowest cold damage done to villain targets was 41
The minimum Biggest Cold hit was 5. (Could doing at least one hit of 5 or more damage be required?)
The lowest amount of Fire damage dealt was 29
the lowest amount of Fire Damage dealt to self was 29
There is not a single instance of an unlock where Thermodnamics actually does cold damage to Zero. Of course there is not a single failed unlock with him doing cold damage to himself with THermo dynamics, but...
You know. There are unlocks where it seems like everything is met, but there isnt a cold damage hit of 5 or greater.
Here is my thought.
1. Do the pre-requisite battles.
2. Freedom Five(non-variant) defeat Progeny in Megalopolis
3. Absolute Zero must have played at least 6 ongoings.
4. Absolute Zero must deal at least 29 fire damage
5. Absolute Zero must heal at least 29 HP
6. Absolute Zero must deal at least one attack of 5 or more cold damage.
