So far there has been a Double Gym Leader battle(Mosdeep City Gym, Tate&Liza), but how about there being two champions of a region that decide to co-exist as Champion of that region, or perhaps they have a similar close bond like Tate&Liza have.
And what if, if a battle like this existed, you had the choice to either fight them both alone(2 against 1) or choose someone else to come and share the title of Champion with them?
What would u think about this? would it be more challenging? :)
Or how about triple Champion or Gym Leader battles?
Your thoughts? :)
