The Seraphic Wing (セラフィックウィング) is one of Gill's Super Arts, introduced in Street Fighter III: 3rd Strike. Like his other two Arts, it is not visible on the character select screen, and is always available to him.
Executed by performing two quarter-circle forward motions and pressing kick, Gill floats to the center of the screen, and just before the attack proper triggers, he declares, "Let me be the blesser of all souls!". During this time, the attack can be stopped if the opponent hits him; in this case, the Super Gauge Stock is not emptied. Once there, he sprouts six white wings and radiates circular waves of multicolored energy which reach all over the screen.
Seraphic Wing is unavoidable, and cannot be parried. If blocked, it can inflict up to around 25% damage, whereas not blocking can result in an instant KO. The damage inflicted seems to be dependent on where the opponent is on the screen. It can deal up to 20 hits, but after the attack finishes and the wings have disappeared, there is a large window in which he is helpless and vulnerable to attack. However, the only way to deal with this attack without being damaged is to hit him out of it before he starts.
- In Nintendo's Super Smash Bros. Brawl, Tabuu's Off Waves attack resembles the Seraphic Wing in both appearance and function.
- In Namco Bandai's Soul Calibur V, Elysium's Critical Edge functions and even looks similarly to Gill's Seraphic Wing.
