Alright, here's some boss ideas:
The Cadaver Quarterbacker
Health:High
Speed: Medium-Fast(Dash Attack)
Appearance: A humongous Blocklander with stretched and torn but still somewhat effective football gear.
Report #42-003
The Cadaver Quarterback derives it's name from the torn football gear it wears and it's ability to throw undead and survivors alike with professionally lethal results for both parties. About 12-17 ft tall in appearance, infected are able to hitch a ride on it's back as a sort of APC for them to charge into battle somewhat unharmed. Likewise, the Cadaver Quarterbacker can also use other zombies and survivors alike as "makeshift" footballs and toss them at break-neck speeds. Some of the more durable types can use this to launch themselves behind enemy defenses and make it without killing themselves while lesser types and survivors may possibly "combust" upon collision with another being or structure into itty bitty bits. It also has a charge attack to rush in or out of a battle quickly as well as an earthquake attack to stun all around it within a 100 meter radius. Reports of it destroying buildings are also widespread and not surprising due to it's bulkiness. It is recommended to attack on exposed areas where the armor fails to cover adequate protection with high-calibur weapons/Explosives of the anti-tank kind. Will do more research later.
Robo Zombie
Health: VERY HIGH
Speed: Slow
Appearance: Blockhead of 9 ft height and a suit of experimental alloys and various electronics adorning it.
Report #46-007
The Robo Zombie appears to be the result of an experimental cyborg whom judging by the bite marks may have become infected. It utilizes a variety of experimental and/or over-the-top weaponry such as a coilgun, rocket launcher, minigun, flamethrower, and other various conventional weaponry as well as an experimental concentrated energy rifle that disintegrates organic matter. The extent of it's arsenal is unknown at this time as well as the possibility of more of it's kind cannont be ignored currently. The armored suit protects it from a variety of conventional weaponry except on the small power source located on it's back. Theoretically, one MIGHT be able to blast off plates of it's armor with ENOUGH firepower or the sort to expose itself to damage. I haven't been able to study this being as well as the others and changes may be made to it's overall physiology and combat prowess when deemed needed. Will research more later.
