Goliath is human experiment No.1 of the Eden Project. The liquid Soulstone armor rig developed by Experiment Area 7 is capable of injecting the Soulstone’s energy directly into the human body. Due to this, Goliath suffered serious physical mutations, including a significantly bulked-up figure and absurdly tough muscles.
However, this "super soldier" worked a bit… too well. He absorbed the Soulstone energy at a pace that blew away the team’s estimates. Due to this, his vitals dropped rapidly as time went by, all the while developing a violent temper. Now, the only way for him to extend his own life is by taking the lives of other creatures.
