Grid Omega (グリッドオメガ, Guriddo Omega) is an offensive hissatsu tactic.
Inazuma Eleven Ares no Tenbin
Outei Tsukinomiya used it again during the match against Inakuni Raimon. He first tried to use it, but Haizaki managed to intercept the ball before it was finished. Nosaka Yuuma started it later again, and finished the three phases, throwing all players in the air and down on the ground. Because of that, Nosaka scored the 1-0. However, because of intense training on Inakunijima, Inakuni Raimon were able to take the tactics and continue playing, thanks to the vaccuum wave made by Haizaki which made the players land safely.
Inazuma Eleven Orion no Kokuin
As Inazuma Japan were about to challenge the Guardians of Queen with Grid Omega as a way to save them, Guardians of Queen themselves used the tactic. This caused all members of Inazuma Japan to lie exhausted on the ground while also in disbelief.
First, a leading user reaches their arm outwards and signals the beginning of Grid Omega. All the other players rapidly dash toward the opponents as a gust of red wind washes over the opponents. By phase two, all of the opponents are sucked into a huge red tornado, circulating around and off the ground. By phase three, the tornado is released and all the players fall towards the ground, causing pain and a great disadvantage to the rest of the match.
