When performed, Waluigi laughs and summons multiple thorny purple vines from his hand that extend in front of him, entangling and trapping opponents that make contact. Upon trapping opponents, Waluigi uses the vines to throw them in the air and jumps up to them. He then shouts "Waluigi!" and a purple vortex appears behind him, briefly transforming his face and mustache into tones of purple and white as a long white vine appears in his hand. He then delivers a powerful whip strike in front of him with the vine, dealing 40% damage and strong knockback to opponents hit. As the vortex disappears, Waluigi pulls the vine back and poses with a rose that appears from it, ending the move. If Waluigi fails to trap any opponents initially, the vines will instead fall to the floor and Waluigi will be briefly dejected, pulling the vines back as the move ends.
Vine Megastrike originates from Mario Strikers Charged as Waluigi's Mega Strike, known as Purple Spike. When using it, Waluigi leaps high in the air, creates a deep purple vortex behind him and whips the ball with a purple whip made of thorns. The purple thorny vines Waluigi uses to trap opponents with are based on Waluigi's Super Ability from the same game, Wall-Luigi!, which increases his speed and creates vines behind him that act as a wall. Unlike how it works in SSF2, Wall-Luigi!'s vines do not directly trap opponents but instead can be used to surround them so they cannot interfere in the match for a certain period of time.
