The Phalanx

Since Cable will be introduced in the second Deadpool movie, it would be pretty nice to see how he (Cable) received his metallic arm.

The Phalanx is a cybernetic species, able to infect organisms and thus increase its numbers. The infected beings retain some memories from their time prior to being infected, but they are no longer what they used to be. Their gain superhuman powers, including shapeshifting and teleporting. Which is pretty neat.

We can see the Phalanx as figuring sometime in the X-Men’s future, maybe as some other type of weapon used against the mutants. Since it cannot infect those with the activated X gene, Phalanx could be used by some mad scientist to enhance humans in their battle against the new species.
