Spear Man for those that wanna see it right here...
Name: Spear Man
Designation: DW2N-022 Robot Master
Weapon Get: Spear Rain
Other weapons: Spear Nun-chunks, Spear Stab, Spinning Deflect
Background: Yamato Man was rather successful during his run (I'm refering to the RM6 manga here, he gave Rockman the most intense fight in the whole manga). So, DWII decided to build on the basic concept, and Spear Man was born.
Spear Man is more forminable with tougher armour, and a double-speared weapon.
His main weapon, Spear Rain, allows him to summon a rain of spear heads down onto his opponents, piercing them multiple times. Spear Rain is especially effective against armoured opponents. His other weapons include Spear Nun-chucks, where he can separate his double-speared weapon into a pair of spear-tipped nun-chucks. By spinning these nun-chunks rapidly, he can deflect buster shots (Spinning Deflect), or jumping into the air to summon Spear Rain. He can also thrust his weapon into his opponents (Spear Stab).
Character: Basically the same as Yamato Man, with a warrior spirit. Honourable too.
Weakness: Rather tough armour... And his weapon can pierce through armour... Maybe blow them back at him... Aero Tornado...
And here's the Master Weapon.
You get... SPEAR RAIN!
You get this weapon from Spear Man. Megaman jumps into the air, and rains down multiple spear heads onto the opponent. This can only be used while Megaman is in a jump.
