Origin 

An Atlantean who has spent sometime disguised as a human. After the villain Nitro devastates America by destroying a school in Stamford, killing many lives, including the lives of many members of the New Warriors, Janus and many other Atlantean sleeper cells are activated. Their new missions are to locate and capture Nitro, for the crime of killing Namorita, cousin of Namor. Janus is contacted by fellow Atlantean Amir with new information, and along with Paul, Amir's husband the trio set out to capture Nitro. They locate him, but must face off against Wolverine in order to capture their prey. Although Wolverine is impressed by Janus's strength, he exploits Janus's need to use technology to breath on land, and removes his breathing apparatus causing Janus to choke. After realizing they share a common enemy in Nitro, an alliance is made.
