Deathray
From Jenny Everywhere Wiki
A Deathray was created by Professor Madison at some point before 2011 in Reality Z-25 31-H. She kept it under lock and key in a vault in her secret laboratory in the Mojave Desert. However, one night, her jealous assistant Hank Richards took command of another one of Madison's inventions (the giant robot nicknamed “the Rabbit”) and used it to break the vault open. He subsequently mounted the weapon onto the robot's right arm. However, the next day, the scheme was exposed and the robot was destroyed by Kelly, with the Deathray presumably lost with it.
