At WrestleMania 21, the concept of the Money in the Bank ladder match was introduced; a six-man ladder match that featured a briefcase suspended above the ring containing a contract that guaranteed the winning Raw brand participant a world title match at any time and place of their choosing within one year up to the next year's WrestleMania, in which Edge went on to win this match. In the main events, the WWE Championship and the World Heavyweight Championship passed on to John Cena and Batista respectively by defeating John "Bradshaw" Layfield and Triple H in their respective matches. Eddie Guerrero's last WrestleMania match took place at WrestleMania 21 against Rey Mysterio, before he died later that year.
