The Tesla was originally invented by Nikola Tesla, but when Claudia Donovan became an agent she made one herself. Originally, Teslas could only fire several times between charges, depending on their setting. Once they ran out of power though, the Teslas would have to be returned to their carrying case, where they could be plugged in and recharged by some as-yet unexplained means. Claudia discovered a means of creating a self-charging system for the Teslas, as well as miniaturizing the Tesla for better concealment.
