What is the gap in power level?
Let's use Thor for the high herald, Thanos as the trans, and Odin as the skyfather. Power here is measured by blast output strength, physical strength, and durability, but not versatility (speed, exotic powers like time control, bfr ability, etc).
What is the average gap between a high herald and a skyfather?
Measure in multiples of Thors stacked in power.
First answer these; then make the conclusion.
1. What is the average gap between a high herald and a trans?
Measure in multiples of Thors stacked in power.
2. What is the average gap between a trans and a skyfather?
Measure in multiples of Thanos stacked in power.
I would go first. I believe about 3 of Thors stacked in power (blast power, strength, durability, etc.) would equal Thanos. I feel Thor with Mjolnir hits can affect Thanos on a low level from the history of showings.
Then, I would say about 3 Thanos can equal Odin.
Thanos didn't quite affect Odin at all when they fought directly. But again Odin has been affected slightly by Thor.
In conclusion, I come up with roughly 9 Thors stacked that can match Odin in strength, blast power, and durability. Please support your opinion. Try not to cherry pick 1 showing. Use various showings in history.
