Supporting role. Pulsefire Ezreal is a fugitive being hunted down by the Rememberancers, "time police" trying to stop people like Ezreal from creating paradoxes and destroying timelines. He's also Ekko's partner, both for work and romance, though he and Ekko are new to the latter and are both terrible at it. Ezreal is seemingly wildly overconfident, yet under his boasting is a bit of truth as he's incredibly intelligent and determined even under pressure. Still, he's also very reckless and gets Ekko into trouble more often than not.
