Magma Blade

Magma Blade (マグマブレード Maguma Burēdo?) is the Special Weapon that X gains from defeating Blaze Heatnix in Mega Man X6. When equipped, X slashes with his Z-Saber that is infused with flame energy, creating two fireballs (that are as large as X himself) forward in the process. This is a fairly quick attack and has a fairly wide vertical range. Both the flame saber as well as the fireballs produced can damage enemies. The flame-infused Z-Saber slash will also deal slightly more damage to enemies than the ordinary Z-Saber slash X uses without any Special Weapons equipped.
When charged, X fires one large fireball straight ahead, then seven more fireballs come flying in heading in the same direction, around the same level that X is at. The angle of forward travel is random in nature but all of them will follow the first fireball's forward direction, which can hit enemies at a much wider vertical range. If X is hit before he fires the first fireball, the Weapon Energy will be wasted. However, if X takes damage after he has fired the first fireball, the attack will continue on until all eight fireballs are released. This is the only Special Weapon from defeated Mavericks in this game that utilizes the Z-Saber that he obtained from Zero in Mega Man X5.[1]
This weapon is primarily Blizzard Wolfang's weakness, causing 5 units of damage to him and 8 units of damage if the weapon is used in its charged state.
