Just pitch a character or two, their abilities, strengths, and weakness, and when we have enough combatants from different people, you then challenge another someone else's combatant. ( I was thinking of maybe taking a page out of Death Battle and maybe having the two combatants have a connecting theme like both are martial artists or have opposing elemental powers etc. but let's see how this plays out first.)
@Zaboem I was thinking that both combatants agree on the type of combat/arena their characters engage in beforehand. (I.E. Duel, 2v2, Team Battle, Tag Team, Free-for-All Battle Royale between multiple creators, whether or not the battle is to the death etc. etc.)
P.S. I was thinking of adding at least one or two more of my characters for people to challenge, but I think I'll wait until I have my first match with the Masked Puppers before I add someone else.
