Lair, Lair is the second Halloween episode of the Disney XD original series Mighty Med.
Plot
Oliver and Kaz attempt to visit The Annihilator’s lair to take his collection of superpowers and restore them to the superheroes, but they end up trapped in space by a still evil Skylar (though they still don't know she's evil). Ultimately, it became part of The Annihilator's plan to create an army of evil superheroes to take over the world. Meanwhile, Alan insists on attending his first Normo Halloween party.
