A Mary Sue generator. Well, now I have seen it all. The programming has some bugs though, it seems that some of the writing it conjures up sometimes conflicts with itself. By that I am suggesting that it become impossible in literacy terms. I actually have created Mary Sue Characters in my time.
My first was a Gary Stu(very new and young at this time), a necromancer however I still keep him alive, granted I've balanced, modified and changed about twenty times to make him more reasonable. My other is on Role Play Gateway which is basically a biological structure-organ building-that was compacted to a living form (sort of like a mobile form, since a big building of guts can not move at all) he had a lot of powers. Mostly due that I cross bred the mobile form with the building form. If I kept the two separate he would of actually be very well set out but sadly I got embarrassed at how I messed up and threw him to the furnace.
The idea for the latter was indeed strange, but I have a habit of creating rather whacky characters, I love to experiment and be weird designs, such as my creation the Aviosa-Bitter and Sweet or Okikay (my Doppelganger)
It is insanely easy to create a over powered character, although Mary sues and Gary Stu's are somewhat an orthodox creation. Most people that create these are ether un-fit to role play to begin with through emotional cripplment or lack of intelligence, sometimes though these are simply created on a bad day of writers block.
I should also mention that I beleive that there is nothing like a bad idea, just bad executions of ideas. But..some sanity helps too.
