OK, here's how it works. You create a character. Then you give them three moves, each with a certain amount of PP and HP it takes away. Here's an example:
Character: Gary
HP: 100
PP: 50
(PP and HP must add up to 150)
Slime Ball: Costs 10 PP, takes away 20HP
Shell Shock: Costs 10 PP, takes away 20HP
Meow of Death: Costs 20PP, takes away 40HP
(Each character must have 3 moves that combined take away 80HP, and a move can take away no more than 50 HP. For every 2HPs it takes away it will cost 1 PP, meaning a move with 10HP,10/2=5, so it'll cost 5PP)
That's my character. When you want to challange someone just ask them.
For any questions, just ask me.
