Rebecca (5★) Rebecca is an Electro Pistols resonator who functions as a Sub-DPS and Amplifier, specializing in Basic Attack DMG and team-wide damage buffs. Her gameplay revolves around freely switching between two states, Huntress and Guts, to build resources and amplify her team.

Rebecca swaps between states by casting her Resonance Skill or Intro Skill, with Huntress granting Crit. DMG and Guts letting her ignore a portion of the target's DEF. In either state, she builds Fervor through Normal Attacks and Resonance Skills while passively regenerating Hot Hand over time. At max Fervor, her Heavy Attack is replaced with the enhanced Rat-tat-tat!: Huntress or Bang-bang-bang!: Guts, consuming all Fervor for a powerful hit.

At max Hot Hand, casting her Intro Skill or Resonance Skill triggers A Girl Gets What She Wants!, granting her the stat bonuses of both Huntress and Guts at once. Her Resonance Liberation - Party 'til Dawn! then deploys the Mk. 31 HMG, creating a Stagnation field where she auto-fires to accumulate Overload, pressing Normal Attack or Resonance Liberation to enhance her firepower - the higher her Overload, the greater the Mk. 31 HMG's damage. Once Overload is maxed, she caps off the rotation with BOOM! Fireworks!.

Rebecca is built to amplify her team, especially Lucy. Her Outro Skill: Preem Choom summons a turret and grants the next Resonator Edgerunner Bonds for All-DMG Amplification and stacking Heavy Attack DMG Amplification through Overlimit, with Lucy automatically receiving max stacks and able to enhance the turret. She also inflicts Tune Hack - Shifting through several of her skills, boosting the team's Tune Break Boost and powering the Cyberpunk duo's shared Tune Hack synergy.
