A counter. Wonder of U plainly tells the opponent that they cannot touch it as its eyes begin to glow and it leaves itself open. If struck by a non-Throw melee attack, including HHA and other GHA, the GHA will trigger.
Out of nowhere, the opponent is assaulted in sequence by a runaway cart, a hospital gurney, and a speeding car, launching them into the air and leaving them incapacitated on the ground. Wonder of U reminds that they were warned while a heavy rainstorm randomly starts, and the ensuing rain rapidly damages the opponent while they're down. The Stand ominously states that calamity is coming as it slowly looks skyward.
The dark rainclouds are suddenly parted by a large, broken-off piece of airplane plating falling from the sky. The plating's random trajectory eventually brings it falling straight towards the downed opponent, and it accelerates to red-hot temperatures. Wonder of U begins a sentence clarifying that calamity is not a force of justice; Toru briefly peaks his head out from hiding to finish, whispering that calamity is also not evil. The plating finally crashes into the opponent at terminal velocity, generating a fiery explosion and shockwave that sends them flying, while Wonder of U stands facing away from the scene.
Wonder of U's current Calamity Level influences the damage of this GHA. As a counter GHA, this is one the highest-damaging attacks available, comparable to the GHAs of Diavolo and Enrico Pucci. It is capable of depleting almost half of the opponent's health at the minimum, and increases to an upper limit of 787 damage when both the Calamity Levels and GHA are at Lv 3 and Wonder of U itself is in Rumble Mode; This would make it the second strongest attack in the game behind Diavolo's GHA under the same circumstances, capable of leaving any character at critically low health if triggered from a full health gauge and otherwise instantly KO'ing at a lower health level.
