Everyone else is doing GLaDOS or Bowser, I wanted to be a bit different.BackStory:
Luigi is one of GLaDOS' other test subjects, but instead of portals, she tested him with personalities. She made a devise that could transfer the AI personalities, into human beings, with the human's personality going into the Core. The test was successful, as she switched out Luigi with one of her own personality cores, the Anger core. When trying to capture Mario, as a last resort she sends the anger core(Now Luigi) to stop him.
Tell me what you think, any suggestions?
