Zi with black sclera or white sclera?

In the main universe, the creature with black sclera is a parasite that will emerge in its mature age and start finding other parasites to breed. In this case, Zi's design from the beginning has black sclera and it is confusing to distinguish him from other parasites. To solve this confusion, how about Zi's design with white sclera and just make a "what if...?" version. Zi is a parasite with black sclera in another universe where he is a parasite and his parasitic nature is aggressive (red eyes). (There are also more passive parasites with turquoise eyes and there are also neutral parasites that have white eyes)

Can you guess who he switched parasite roles with in this universe?
