An engineer with peerless armor-constructing abilities, Brigitte Lindholm is a valiant squire who fights on the front line to protect her allies.

The youngest of TorbjÁ¶rn’s daughters, Brigitte is an adventurer who travels with her godfather—Reinhardt Wilhelm—to fight for those who cannot fight for themselves. Previously, she aided Reinhardt by repairing his armor but as time has passed, Brigitte has realized that there is some damage that her hammer cannot fix. Her desire to help stronger than ever, Reinhardt is training her to fight while she built her own armor in secret. Now she fights alongside him on the front line, where she can make an even bigger difference.
