Magneto Vs Gadget

I have heard the theory that Inspector Gadget is actually Dr Claw and after an accident he replaced himself with an android-replica to look after Penny and Brain. Myself I always thought that Gadget was an experiment/ project that was to create a detective version of Robocop but turned out to be a huge failure, ethically and physically, as the procedure left the subject insane. He was awarded a genetically modified canine and a family member to care for him.
Magneto, of course, was the most obvious choice for my one-sided fights; not only are his powers the very antithesis of Gadget's abilities, but their personalities couldn't be more polar opposite...
