I have got a Bitchanger answer nearly ready, but I think I have put the code in a silly spot. I thought it would be a good idea to keep it with the brainfuck derivatives on line 8. That leds to me having to add more characters to cancel out the effects of the bitchanger on the Agony, brainfuck and Perl 6 than what make up the actual bitchanger code. So I'm going to try putting it after the main polyglot long brainfuck loop.

@Potato44 I just updated last unswer

@stasoid thanks for warning me, doesn't effect the part I was working on.

I have an answer ready but I'm too tired to the write-up currently. If someone else wishes to answer before I answer that is fine because this program is easy enough to change which number it prints.
