Let's play a game /vp/. You've just moved to a brand new region to take over as a city's gym leader, but there's a catch. You have to be a dual-type gym leader, and your gym's theme is based on the two types you get.

Roll, and then pick your types from the last two digits. Each digit gives you two choices, and you can pick which type of the two you want to use. Dubs is stuck with both types of that number.

>0 = free pick
>1 = fire or water
>2 = grass or electric
>3 = normal or flying
>4 = steel or dark
>5 = ice or fighting
>6 = poison or bug
>7 = rock or ground
>8 = dragon or fairy
>9 = psychic or ghost
So if my last two digits were 15 I would have the choices of Fire or Water and Ice or Fighting to combine.

Once you have your types, give your gym a theme that merges both types as naturally as possible, you can also make a postgame team or a hard mode team for fun.

Unless no pokemon exist with the type combination you got, you must make your ace a pokemon of your given type combination.

And (optional) give your badge a name + a fitting TM reward.
