The Min/Max values are calculated for a Pokémon at level 100. Maximum values are based on a beneficial nature, 252 EVs, 31 IVs. Minimum values are based on a hindering nature, 0 EVs, 0 IVs.
Tiers are calculated from the Pokémon with the highest available stat for that stat. Example: Blissey has the highest base HP at 255, so all tiers are divided by 6 from 255. Whereas the highest DEF is calculated from Shuckle at 230. This shows a better representation of where a Pokémon's base stat lies compared to the highest that stat can be. The length of the stat relative to the Tier also shows where it sits inside the Tier.

Eternamax

As a result of Rose’s meddling, Eternatus absorbed all the energy in the Galar region. It’s now in a state of power overload.

Infinite amounts of energy pour from this Pokémon’s enlarged core, warping the surrounding space-time.
