Big bang attack from the Dragon Ball Z series games, I swear the amount of times I used that on the PSP game was just too op than most attacks.
Also the Proton Collider from C&C Red Alert 3 since it fired proton shots that splashed your base and caused heavy splash damage, if you had walls built that were anywhere close to your structures the proton shots would cause a chain reaction where the walls would explode one by one and any buildings nearby would die instantly. Compared to the Vacuum imploder (sucks units in and kills them instantly/does damage to anything within it's radius) and Psionic Decimator (immediate explosive damage with a set range), the Proton Collider was probably the most op super weapon in that game.
Mankind, in its arrogance and self-delusion, must believe they are the mirrors to God in both their image and their power. If something shatters that mirror, then it must be totally destroyed.
