Through doing rescue missions, the player will get some rescue points depending on the mission's difficulty. When the points reach a certain level, the team rank rises for a level.
At the start: Normal Rank (lowest)
50+ points: Bronze Rank
500+ points: Silver Rank
1500+ points: Gold Rank
3000+ points: Platinum Rank
7500+ points: Diamond Rank
15000+ points: Lucario Rank (highest)
Once a player's team rises a rank, the badge will change colours. Also, the rank can't decrease, so once a player reaches a new rank, they cannot return to the previous rank.
