Shadowclaw is an influential Mewtwo combo video by famous Mewtwo professional Taj, named after Mewtwo's forward aerial. It popularized several Mewtwo techniques, such as repeatedly falling off a ledge and immediately teleporting back, and jumping off an edge while charging a Shadow Ball to edgeguard.
Impact and Legacy
Although Taj was always known as a good Mewtwo player, the video essentially made him the clear best.
Several sequels, titled Shadowclaw 2, Shadowclaw III, and Shadowclaw IV has since been completed and released.
