Advent Neon

Neon is a Synthezoid who carries a power called Step Resonance: the harder and longer they deal damage without taking any themselves, the stronger they become — growing toward a near-unstoppable level of force. The catch is that a single hit resets everything. Neon is fast, powerful, and built entirely around avoiding damage while inflicting it continuously. When Neon's creator is killed at the start of the game, they take to the city of Neopolis looking for any way to bring him back.
