Neo-Urban XIII is an Exclusive Cyber-Necro mutant. It can be obtained by collecting all the mutants in the Big Boss! Reactor, or collecting all of the mutants in the Saber column of the Legendary Mutants Bingo grid.

The relationship between Eva and Urban has always been a mix of attraction and hatred. This creature illustrates exactly that. For years, Baron Urban has engaged in self-cloning experiments to create a perfect body for himself. The first clones died quickly, destroying parts of Urban's lab with their fury. The XIIIth was a failure too, but it survived. Its only motivation is to find Eva and absorb her. In the meantime, it destroys indistinctly every Mutant in its way.
