Red

Red (レッド) is the leader and namesake of the group Red Alert, a syndicate that hunts Mavericks, but he himself became Maverick. His organization was progressing along pretty well until Red met up with “the professor” (Sigma) and changed his plans. Eventually, he regrets forming the alliance with the professor, and, after being defeated by Axl, tells him and his friends to leave him to die in his base (he earlier set it to self destruct.)

Boss Guide
Right when the battle starts, equip the G-Launcher weapon. Run towards him and release a normal shot. These shots are very powerful and will lower his life greatly. He will always be standing in the middle when the battle starts. When you've hit him enough, he will vanish and appear on another platform. He will then create two copies or illusions of himself which will always appear near you. They will first flash around you, before they appear clearly and slash quickly at you. When you see them flash, quickly jump to another platform to evade them. When Red appears again, fire at him and he may use another attack. He will throw his scythe at you. When you see that he is about to throw, jump away to evade it. Another attack is that he will fire an energy wave at you, both horizontal or vertical depending on what you're doing. When he fire an energy wave at you after you fire G-Launcher at him, switches to Zero and use Hieijin. You will eventually avoid the enegy wave and He will be hit by Hieijin, then switches to Axl and fire G-Launcher at him again. Use this same combo again and again and you will be easier to defeat him. When you've hit him for a few times, he will create pink tornados on some platforms. When you see a tornado begin, quickly jump to another platform to evade being heavily hit.
