I’ve read somewhere about the unlimited terror of reverse-chiral life. Basically all molecules in life will be left-handed or right-handed - mirrors of each other. All life on Earth has the same chirality for all molecules, but scientists could now theoretically create opposite-chiral life which is incompatible with Earth’s biosphere. Bacteria that cannot be preyed on by any virus and which cannot be killed by immune system bacteriocide proteins because they don’t match the key to the lock any more.

It’s always off from possible as they’d need to create life from “scratch” from synthesized reverse chiral molecules.
