The three initial partners
A new Guest entry offered all three partners. The selection screen says your chosen partner is the first member of your League; the other two join later through a challenge and capture in a run. Their exact challenges have not been verified here.

| Partner | Game role | First move | Passive emphasis |
|---|---|---|---|
| Bulbasaur | Healer | Vine Whip | Healing and regeneration |
| Charmander | Fiery Assault | Ember | Fire and conditional damage |
| Squirtle | Defender | Water Gun | Armor and shield |
Bulbasaur
Passive — Synthesis. Synthesis adds regeneration, improves healing, and restores a little health when Grass attacks connect.
Starting move — Vine Whip. A physical arc aimed at the nearest enemy, with a chance to root it.
Later moves listed in the League: Razor Leaf, Sleep Powder, and Solar Beam. The profile lists these as the partner's kit; a new move must still be selected when it is offered during a run.
Choose Bulbasaur if you want a kit built around sustaining health. Its healing passive is useful to understand early, but it does not remove the need to keep moving.
Charmander
Passive — Sea of Flames. Sea of Flames increases Fire damage and adds a damage bonus while health is below 40%.
Starting move — Ember. A special projectile aimed at the nearest enemy, with a chance to burn it.
Later moves listed in the League: Fire Spin, Flamethrower, and Fire Blast. The profile lists these as the partner's kit; a new move must still be selected when it is offered during a run.
Choose Charmander if the Fire kit appeals to you and you want a damage-focused passive. The low-health bonus is a conditional effect; it is not a reason to deliberately take hits.
Squirtle
Passive — Torrent Shell. Torrent Shell adds armor and shield, plus a damage bonus while health is below 40%.
Starting move — Water Gun. A special projectile aimed at the nearest enemy, with a chance to apply wet.
Later moves listed in the League: Bubble, Rapid Spin, and Hydro Pump. The profile lists these as the partner's kit; a new move must still be selected when it is offered during a run.
Choose Squirtle if you prefer the protection described by its passive. In our Survival test, Water Gun handled early automatic attacks and the first level-up offered Bubble as a new move.
How to make the choice
The advice above follows the displayed kit descriptions. We have not measured comparative win rates or tested optimized builds, so there is no best-starter ranking here.
For a first session, pick the passive you want to learn: healing with Bulbasaur, Fire damage with Charmander, or protection with Squirtle. Then use a short run to practice movement and read your first upgrade cards. The beginner guide walks through those steps.
