Bayonetta's Final Smash is Infernal Climax. She activates Witch Time to affect the whole stage. While this effect is active, Bayonetta has a limited time to deal damage to her opponents in order to fill up the Climax Gauge. The Climax Gauge will also fill itself up slowly. Once it is filled, she has to deal knockback to any opponent before a cutscene occurs. The cutscene consists of her using her hair as a conduit to summon Gomorrah, who then damages any opponents suffering hitstun from Bayonetta's attacks by chomping them four times before they are launched with set knockback. The attack button can be mashed during the attack to fill a second Climax Gauge that deals an additional 15% after the cutscene. Once the cutscene ends, anyone with 100% or more will be instantly KO'd. Anyone below 100% will take an additional 10% as the Final Smash ends.
- Infernal Climax has considerably less base knockback (120 → 90) against opponents not instantly KO'd by it, making it less likely to KO off the blast lines if they are caught near them.
