Short Answer 
In “Pokemon Brilliant Diamond,” the obedience of your Pokemon is linked to the number of badges you have; with each badge, the level cap for obedience increases. Players can have full obedience of all Pokemon once they collect all 7 badges, allowing for greater training and evolution of stronger Pokemon.
Step 1: Understand Badge Requirements
The obedience of your Pokemon in Pokemon Brilliant Diamond is determined by the number of badges you have collected. Each badge allows you to command higher-level Pokemon. Here’s how it works:
- 0 badges: Pokemon above level 10 will not obey.
- 1 badge: Pokemon above level 20 will not obey.
- 2 badges: Pokemon above level 30 will not obey.
Step 2: Progressing Through Badges
As you earn more badges, the level threshold at which Pokemon will obey you increases. This means you can train and evolve stronger Pokemon as you obtain additional badges. Here’s a continuation of the badge effects:
- 3 badges: Pokemon above level 40 will not obey.
- 4 badges: Pokemon above level 50 will not obey.
- 5 badges: Pokemon above level 60 will not obey.
Step 3: Full Obedience at Maximum Badges
Once you acquire all 7 badges, your Pokemon will fully obey you, regardless of their level. This incentivizes players to continue battling gym leaders and collecting badges throughout their journey. Summary of the last badge effect:
- 7 badges: All Pokemon will obey, regardless of level.
