Unknown Entity

Force Monster that Amanda Evert controlled came from The Wraith Stone in Peru. Whenever Amanda uses this stone she becomes one with the terrifying entity, then she uses this power to attack her foes. She only uses this power once, when Lara kills James Rutland in the Bolivia Redux level and Amanda was furious so she decided to finish this once and for all. When Amanda is defeated she loses The Wraith Stone.

Origin
First appearing within the flashback sequence in Peru, Force Monster was awoken by a group of young archeologists on an expedition, including a young Lara Croft. However, as Lara did not witness the release of the creature, it is only assumed it was disturbed when the team broke a sealed chamber of some sort. The creature then proceeded to slaughter the archeologists, leaving only Lara and Amanda to escape the massacre as the site collapsed.

The only other survivor, Amanda Evert, did not leave the tomb until some time later. The creature spared her because during her attempt to escape, she came into contact with The Wraith Stone, which linked her spirit with the Force Monster's, therefore saving her life in the process.

From that day, Amanda could summon and even merge with Force Monster at will, simply by wielding the stone which she wore as an amulet necklace. Using the creature for her own endeavors, she trained it to attack anyone who apposed her, including Lara on two occasions. The creature met its supposed demise when Lara used a newly re-forged Excalibur to kill the Force Monster, severing the connection between it and Amanda.

Abilities
Force Monster appeared to evolve as it aged, growing larger in size and gaining the ability to fly, as apposed to running around on it’s arm like appendages. As well as it’s razor sharp claws, it also gained the ability to shoot projectiles of harmful energy. When under Amanda’s control, she can use The Wraith Stone to heal its wounds.

Appearance
Force Monster resembles a demonic creature with no legs, two large arms with long claws, and a skull like head with sharp teeth and yellow, glowing, featureless eyes. It also has a number of long dark tendrils protruding from its back, and is clouded in what resembles black smoke.
