Elixir (Joshua "Josh" Foley), is a fictional character, a mutant in the and a student at the Xavier Institute. He first appeared in New Mutants vol. 2 #5, and he is one of only a few students to retain his powers in the wake of House of M.

Josh Foley first appears as a member of the Reavers, an anti-mutant group led by Donald Pierce. When Cerebro detects a mutant in the area, Danielle Moonstar and Karma investigate. The Reavers attack Moonstar's New Mutants squad, and one of Foley's allies is severely injured. Leaning down to aid his friend, Foley's mutant power manifests and he heals Laurie Collins.

Outed as a mutant, much to his own surprise, and rejected by his friends and family, Josh reluctantly joins the Xavier Institute and becomes Prodigy's roommate, a situation neither finds appealing. Unable to overcome their bigotry, Josh's parents sign legal guardianship over to Dani Moonstar. He is assigned to Dani's New Mutant squad who eventually reach out to him as he comes to accept his mutation.

Shortly afterwards, a depowered Rahne Sinclair, formerly known as Wolfsbane, visits the X-Mansion. Josh is instantly smitten by the new "wild child" Rahne, and sneaks out of the Institute at night to go to a bar where Rahne is playing pool. Josh realizes that her new attitude is a way of letting out instinct she had previously been able to blame on "the wolf." The two kiss, and Josh unconsciously heals Rahne's depowerment. The wolf takes over and she loses control, slashing Josh open. Fortunately, Laurie witnesses the attack and uses her pheromone powers to drive away Rahne.

Elixir has not been a contender in any CBUB matches.
