*sinister device starts powering up and drains energy out of me*
Whoah...what was in tha-- *passes out*
*Device creates an artificial demon with heavy armor and fire surrounding it using the demonic energy*
*gets up*
Ooh. Now, I can't judge from one example but this machine seems to be using the energy you give it to create something matching the elements of the energy provider. So it created a demonic fire creature, judging by my aptitude with those two elements. Though, until someone else touches it, I won't be able to tell. The effects may vary for the different type of energies it can receive. In the meantime, this artificial demon is mine, by right. Important tests to carry out!
