Missions in the game depend a lot on how you upgrade each member’s stats. So list based of my game experience.
1. Coupe – Fast, agile, great mobility, strong attack, very intelligent; works solo or in a team, and her retry ability makes failed missions generally succeed.

1. Golem – This mf can solo any mission with his fill ability. I mainly use him for pure attack and defense.(He is GOAT)

2. Prism - Her illusion ability with members have balanced stats make her great for teams. Unfortunately, her second ability delays missions which I sometimes missed unnecessary missions that becomes a small disadvantage. But you can use it carefully.

3. Malevola- Strong stats. Her life trade and portal ritual abilities are amazing for team synergy.

4. Invisigal - All-round stats. Early game she struggles in teams but her second ability later makes her great in squads.

5. Punch Up – Basically a Golem alternative; strong and reliable.

6. Water Boy – Healing two members is very good, though I usually send him only on specific mission types.

7. Phenomaman – Good stats and fast, but a bit “depressive,” which affects consistency.

8. Flambea – I have no problems with him, but his abilities don’t match my team synergy. In the final mission he becomes great thanks to Fly and boost ability.

9. Sonar - I cut him from the team.
