This is a thing I did many years ago, and really enjoyed, so I'm going to post here and hope someone wants to enter the ring.
The idea is to have my original character battling versus your original character in a comic we make, taking turns in drawing the pages. The one coming up with the best moves wins.

There's some rules, though, but most of it should be common sense:
-Your character must be yours (no stealing from other people)
-No god-moding (example: being invulnerable to everything, infinitely powerful, beating the opponent out of nowhere etc.)
-No offensive or humiliating moves (example: low blows, stomping on face etc.)
-No killing moves (examples: punching holes through the opponent, cutting off body parts etc. - The fight is supposed to be an honourable battle)
-No unbalanced characters (your character must have their strong and their weak points, and must have their limits)
-Preferably a human or humanoid opponent (not looking for fighting Pokémon or something )
-Someone who's willing to put in at least a bit of effort in their pages (no stick figures or raw sketches)
-Willing to finish their turn within ~7 days (~1 week per turn)
-A minimum of 1 page, and a maximum of 3 pages per turn

Please post here if interested, and we'll get started.
