| Units | Features |
|---|---|
| Awakened Dori | Attacks enemies with cursed energy in a cone AoE and insta-kills non-bosses, while hitting enemies after crits with Black Flash passive. |
| Hot’n’Cold Boy | Alternates back and forth between two types of attacks: ice spikes that pierce and slow down enemies, and fire wave AoE. |

| Brolee Unleashed | Throws Kamehameha waves repeatedly and does Qi energy explosions with a capped range of 100. |

| Rage Drago | Triples the damage output of all units for 31 seconds and resets on a resummon, adding an extra 50% boost to the unit speed. |
| Salter | Slashes in line AoE, dealing 4 hits, plus throws a projectile, but needs to be closer for some really high DPS. |
| Choz | Fires blood bullets or Piercing Blood line AoE, spewing orbs for a massive Supernova finisher. |
