Mutants & Masterminds 3e Character Builder & Sheet

Welcome to the free digital character builder, tactical character sheet, and power construction studio for the Mutants & Masterminds 3rd Edition (M&M 3e / D20 Hero System) tabletop roleplaying game.

Automated Power Point Bookkeeping & PL Validation

Building superhero characters in the D20 Hero System requires careful mathematical budgeting. This application automates all Power Point (PP) bookkeeping, ability modifiers, and Power Level (PL) cap calculations.

The builder dynamically verifies offensive caps (Attack Bonus + Effect Rank) and defensive caps (Dodge/Parry + Toughness, Fortitude + Will) in accordance with standard Mutants & Masterminds 3rd Edition rules.
