Fan Casting Lionel Curtis/Cyanide in Monstrosities Commando : Mission Skull Island

The only surviving soldier from Glendon's group, he was captured by the Cult's researchers in their lair. He bonded with what they created when they attempted to replicate the alien parasite from Abyss many years ago, before the original parasite was recovered by Alistair MacCregor. The parasite clone and Lionel merged, creating "Cyanide," a dangerous and unstable psychopathic creature who ultimately joined the Commando in the finale.
