Alex Mercer is a Infected Human from the planet Earth in Yusuke 10.


Powers & Abilities[]

Once reanimated by the Blacklight virus, every particle of Alex's form, including his clothing and equipment, becomes comprised entirely of viral biomass. This substance can be manipulated at will. He can absorb the organic matter of other living creatures, converting it into more biomass. This process sustains and regenerates Alex's health and is referred to as 'consuming'. In addition, Alex can consume individuals, absorbing their knowledge, skills, and even their physical form, which he can call upon at will. He can manipulate his physical form to create weapons to attack his enemies, generate armor to defend himself, and take on the appearance of another person to disguise himself. During his battle against James Heller, he displayed the ability to consume multiple of his Evolved soldiers at the same time in order to power up his abilities.

Physical Prowess[]

Alex's shapeshifting powers grant him superhuman physical abilities well beyond that of a normal Human.

  • Shapeshifting
  • Superhuman Strength
  • Superhuman Speed
  • Superhuman Agility
  • Superhuman Endurance
  • Healing Factor
  • Superhuman Senses

Offensive Powers[]

Alex can form his biomass into a variety of weapons, mostly slicing or crushing tools. In combat, he either uses biomass to augment his strength or create various blades and clubs.

Defensive Powers[]

Alex can use two defensive powers, guarding him against enemy attacks and weapons. Alex has two forms of defense, the Armor, and the Shield.

Disguise Power[]

Alex has the ability to assume the physical form of any human he's consumed, though for gameplay purposes the player is limited to the last human they consumed. In this manner, Alex can infiltrate the military as one of them, duck out of sight and emerge as someone else to evade pursuit, and in general avoid drawing attention by disguising himself as someone else.
