Yes, let us set aside our differences and focus on the real threat Crud brother. I gift you these laser rifles to solidify this peace treaty.
well It’s easier to find the creatures that survive basically anything already and assume they will continue to survive in some capacity, even if they mutate heavily in the process. So:
Housecats, Rats, mice, cockroaches, cyotees and feral dogs maybe.
These animals all strike me as animals with good senses that allow them to avoid higher predators, and catch lower prey.
I suspect that top of the food-chain predators will have a harder time surviving without mutations as new apex predators form other dimensions stake their territory.
