Case 70

Case 70 is the PRT designation for a pair of capes who share a single body and have similar powers. So-called due to the phenomena being the 70th anomalous case in total the PRT investigated. A Case 70 situations occur when twins trigger while in physical contact with each other.

Details
In Capricorn's case, only one of the twins was in control of their body at any given time. The inactive twin shared the perceptions of the active twin, but had no way to interact with their surroundings. Only the active twin could pass control to the other, causing their body to transform into the other twin's body. Clothes, armor, etc, is also switched over.

It is unknown how similar the presentation of this phenomena in other parahumans. For example the Tandem twins are able to exist at the same time while in contact with each other.

Examples

 * Capricorn
 * Knot
 * Tandem
 * House of Three (possibly)
 * Zigzag

Background
Twins who trigger normally gain the same power or near-identical powers.

However, if the two are touching at the time fo the trigger then the Agent conglomerates the two people into one individual. It may be due to the agent's makeup.

Post-Timeskip
Case seventies reportedly have a low life expectancy, even compared to other parahumans. The majority of them were already out of the game before Gold Morning.

Trivia

 * The twins Nix & Nyx are not an example; they may have been an attempt to replicate the phenomena.
 * Extremely pedantic people will point out that even monozygotic twins do not have completely identical DNA. Obviously what DNA the shards do use to lock onto their targets is not noticeably differentiated between hosts.
