|The following is based on Fallout Tactics and some details might contradict canon.|
Mary is big, hairy and scary! She saw her brood enslaved and almost destroyed by the Beastlords, so she is wary of most humans, and a little uncomfortable with the alliance she now has with the Brotherhood. Very strong and fast, with deadly hand to hand attacks.
Mary uses the same character portrait as Mother.
Mary appears only in Fallout Tactics.
