Diamond Man - Fights with a blade from his arm cannon. Weapon name: Diamond Cutter
Shard Man - Pretty much a shield weapon, so... Shard Shield
Mirror Man - Reflects Buster Shots, but not Charge Shots. If you've played Street Fighter X Mega Man, it'd be like Urien's weapon.
Shatter Man - Think Chill Man's Weapon, the Chill Spike, but the more you shoot it, the bigger it gets (to a certain extent) Weapon Name: Shatter Stack
Geo Man - Shoots a spread of 3 sharpened Gems. Kind of a combination of Blade Man's and Needle Man's Weapons. Weapon Name: Geo Spike (Not really ice, but I also got a Gemstone vibe from him)
Glare Man - Uses his highly reflective body to either make the screen go entirely white (except for Mega Man) and teleport to another area, or reflect a beam of harsh light at Mega Man. His weakness could be something that either breaks his armor or makes him less reflective.
Weapon Name: Glare Flash; When Mega Man charges, he starts emitting light (perfect for dark areas), then releases a ball of slow-moving light that temporarily lights paths. Of course, the weapon itself doesn't need to be charged.
Verglas Man. No, no es albur, Verglas es como le llaman al hielo "oscuro" en las montañas. como es muy delgado no se ve "blanco" hasta que ya lo pisaste, resbalaste y moriste... es hielo traicionero y la mayor parte de las veces mortal.
