The upcoming Marvel Zombies TV series will feature Ikaris from Eternals — a twist that makes the zombie virus even more disturbing. Eternals introduced a new cosmic group of superheroes into the MCU, but so far Marvel has seemed wary of integrating them into the wider MCU. Chloe Zhao's film may have included a third act in which a gigantic Celestial began to tear its way out of the Earth's core, but so far the Eternals mostly seem to have influenced the shared universe through Kingo's Bollywood career, name-dropped in Ms. Marvel.
Ironically, it now seems the first MCU project to include a cameo from one of the Eternals will be Marvel Zombies, now set for 2024 with a TV-MA rating. The Marvel Studios Animation panel at San Diego Comic-Con 2022 included confirmation of a vast cast list, with the still-alive heroes include Yelena, Kate Bishop, Agent Woo, Red Guardian, Death Dealer, Shang-Chi and Kamala Khan. In a surprising twist, Marvel also revealed at least one of the Eternals will become a zombie — Ikaris, played by Richard Madden in Eternals.

This is a surprising twist, because it means the zombie virus is even more infectious than had previously been thought to be the case. In the MCU, Eternals are synthetic beings rather than organic. The Celestials' previous creations, the Deviants, had gone rogue as a result of evolution, and the Celestials such as Arishem pivoted towards using synthetics precisely because they would not change. This is, therefore, a major moment in that the zombie virus has infected a whole new life form.
The zombie virus originated from the Quantum Realm, but it's reasonable to assume even there it naturally spread through entirely organic beings.
