Helena Walker, an established white character from the ARK game lore, is race-swapped to an Aboriginal Australian paleontologist voiced by Madeleine Madden, with extended flashbacks depicting her mother protesting for Aboriginal rights against white counterprotesters and emphasizing systemic discrimination. Helena's wife Victoria (voiced by Elliot Page) features prominently in these sequences, including a kiss and themes of grief tied to her presumed death as a humanitarian aid worker, foregrounding a lesbian relationship absent from the source material. Additional flashbacks and character arcs highlight shared experiences of oppression across diverse historical figures, with villains like the Roman General Nerva and British scientist Rockwell framed as egocentric white male oppressors engaging in raids, sexism, and betrayal.
