Prolatomebia volubilis

 (or just Walter's suit) was the name for a swarm of micro-abnormals that had a hive mind and behaved as a single organism.

This abnormal was created by Virgil St. Pierre from an abnormal species of telepathic bacteria and was supposed to act as a ballistic protection suit for its host.

When this abnormal is alone it looks just like a puddle of purple slime, but when it comes in contact with another creature, it immediately develops a psychic link with its host and wraps itself around him/her in the form of a suit. The abnormal and its host develop a symbiotic relationship; the abnormal responds to the host's will, giving them super strength, the power to fly, invulnerability, super speed, and various other super human abilities, but the abnormal also feeds off its host slowly draining the life out of them. The host isn't able to remove the suit without seriously damaging their own body, the only way to remove the suit without killing the host is for the host to genuinely want the suit to be removed or to kill the abnormal. The suit also seems to prefer people who were previously hosts over people it has never bonded with.

Virgil St. Pierre's scientists were able to get the suit off its host by suppressing the wearer's prefrontal cortex which severed the psychic link between the abnormal and its host. However, when the scientists tried getting the suit off of Kate Freelander, there was a power surge which not only failed to get the suit off Kate, but interfered with her decision-making, causing her to temporarily go insane.
