Stat alignments
Champions calls these stat alignments rather than natures. Each one raises a stat by 10% and lowers another by 10%, and 5 of the 25 do nothing at all. You can change a Pokemon's alignment freely in Training, so nothing is locked in at capture. The game files ship the 25 names and the 10% figure but not which stat each name moves, so the pairings below are matched to the mainline nature table.

|---|---|---|
| Lonely | Attack | Defense |
| Brave | Attack | Speed |
| Adamant | Attack | Sp. Atk |
| Naughty | Attack | Sp. Def |
| Bold | Defense | Attack |
| Relaxed | Defense | Speed |
| Impish | Defense | Sp. Atk |
| Lax | Defense | Sp. Def |
| Timid | Speed | Attack |
| Hasty | Speed | Defense |
| Jolly | Speed | Sp. Atk |
| Naive | Speed | Sp. Def |

How this differs from the mainline games
The alignment names match the 25 mainline natures, but Champions pairs them with a different stat system. Instead of 252 EVs per stat and 510 total, you get 66 stat points with a cap of 32 in any single stat, and there are no IVs at all. That makes alignment choice more significant than in the mainline games, because you have far less room to compensate with raw point investment.
