BERSERKER: moves like a rook, but captures like a normal chess queen.
VALKYRIE: moves like a bishop, but captures like a normal chess queen.
These pieces are found in Jason D. Wittman's Mad Chess [July 3, 2000].
In Michael Howe's Biform Chess Variants [September 15, 1997] the Rooks and Knights and Bishops have their standard noncapturing moves, but each piece captures using the standard moves of the other two pieces. Thus the KNIGHT captures like a standard Queen.
