Description

Coding agents are a new form of entertainment, both for creators (right now), and for viewers (not as well served, mostly just look at X posts). People are already getting entertained watching agents on a social network (Moltbook virality). Let's give voice & personality to coding agents as they work into a new type of sporting event, with devs able to select coding agent "fighters" with different personalities / styles that compete on the same task and fight it out in a Street Fighter style battle, with the ultimate winner attaining eternal glory.
