Ninetails

Ninetails is a boss from Mega Man X: Command Mission. He is the strongest enemy in the game, and the leader of the Tails Clan. He and the rest of the clan are imprisoned in the Central Tower Basement. To confront him you have to get the Central Key and face the other eight members (Onetails, Twotails, Threetails, Fourtails, Fivetails, Sixtails, Seventails and Eighttails). He's pretty hard to defeat, because he can heal himself automatically. His attack "Nine Fragments" refers to his nine tails, which he stabs into his enemies rapidly, causing 8991 points of damage (9 * 999), what is enough to take everyone out. Furthermore he has the ability to completely drain his enemy's weapon energy with his Puncture Arrows, and the Annihilator Hadoken, a large and devastating energy beam, sweeps over the place and inflicts heavy damage to all of his opponents. Because of his attacks it's not a lie when he says: "My strength is unparalleled!"
