Mega Menace (ギガガガ強襲 Gigagaga Kyōshū, Gigagaga's Assault) is an event added in version 9.6. Like all Gauntlets, progress made in Mega Menace will reset when the event ends, allowing the player to collect the rewards again once the event returns. The boss of this Gauntlet is Mega-Mooth, a variant of Mooth with more knockbacks and long-reaching Omni Strikes.
Mega Menace contains a total of 60 No Continues levels, called On Mighty Wings Lvs, spread across 3 different maps: Mega Menace! (On Mighty Wings Lv1~20), Mega Menace!! (On Mighty Wings Lv21~40) and Mega Menace!!! (On Mighty Wings Lv41~60). After beating a On Mighty Wings Lv, the player must wait for 30 minutes before they may proceed to the next one. Rewards for the first completion of an On Mighty Wings Lv can include Battle Items, Catfruit, Tickets, Catamins, Materials and Leaderships. Every 20 On Mighty Wings Lvs play out the same, but the strength magnifications and enemy base's HP are increased with each level.
