1. Munna, must be female, must have a nature that decreases speed.
2. Tirtouga. Can not evolve until it has fainted 25 times by fire type pokemon. Can not go into fourth gym without this.
3. Snivy. May not evolve until you defeated two of Clay's pokemon with HER and may not evolve again until after Ghetsis is beaten.
4. Klink, must have Gear Grind. Evolve into Klang after defeating a trainers Klink with Gear Grind. Evolve into Klinklang after defeating a trainers Klang with Gear Grind or when it learns Shift Gear.
5. Darmanitan with Zen Mode from the Resort Desert. Must have two special moves, and two physical moves by the end of the challenge.

Can the bolded Pokemon be changed? Bouffalant appears way too late, and grinding at that point would be difficult with only one attacking move.
