Nova Strike

Nova Strike is the Giga Attack of the Ultimate Armor and the Force Armor, and some fans consider this the best attack of the X series. X does an invincible flying tackle that plows through (and destroys) enemies almost effortlessly.

In Mega Man X4-6 X can use this attack infinitely (except in the Force Armor's version, where energy needs to be refilled like normal Giga Attacks). In X8, the Nova Strike is modified along with the Ultimate Armor. It now has Weapon Energy (WE); however, it recharges over a small period of time (a matter of seconds, in fact). The only downside to this is that it prevents the Nova Strike from being used over and over. To compensate for this added weakness, the Nova Strike's travelling distance is increased, and it can now destroy all Bosses in only two hits (the first hit depletes nearly 75% of a Boss' energy, triggering the Boss' Overdrive, which is always mandatory).

In Megaman X: Command Mission Nova Strike is a series of explosions and powerful amounts of damage done to the enemy. His Ultimate Armor is much more different too. This Armor is really great for Fighting Ninetails in Megaman X: Command Mission. It is one of the two strongest Hyper Modes in that game, along with the exclusive Absolute Zero.
