Replacement is similar to Giorno (Requiem)'s ability with its own pros and cons. Dr. Heart makes a transparent blue sphere where the first enemy is and all enemies inside sphere get teleported to the last corner that they turned. The blue sphere ("room") shares its properties with Dr. Heart’s primary attack (same range as his AoE circle). Enemies after getting affected by Replacement obtain permanent immunity to it, so players can’t spam. It's also recommended to use this ability when enemies are on long, straight paths. Using the Operator Orb, the Replacement ability can teleport up to 8 enemies max instead of one.


Troops sell for half their cost of deployment plus upgrades.


  • The name "Dr. Heart" is a reference to Law's occupation as the doctor of the Heart Pirates.
  • The attack sound effect for upgrades zero to four is G3SG1's fire sound from CS:GO.
