The Story of Ekko
Ekko grew up in Zaun's Undercity — one of the children of the Z-City, the kid who could fix anything, whose mind worked faster than anyone around him could follow. His talent for mechanical improvisation and his obsession with how things worked eventually produced the Z-Drive: a device that manipulates time, letting him rewind seconds to undo mistakes, test possibilities, and — increasingly — fight the impossible situations his neighborhood keeps producing.
He built the Z-Drive for one reason: to make sure the worst outcomes didn't stick. Zaun's children lose too much too young — opportunities burned away by chem-baron indifference, accidents that nobody should have to survive, a world that eats potential alive. Ekko cannot fix the system with a gadget. But he can shave those extra seconds, absorb the impact of the worst moments, and redirect enough to matter. He does this quietly, without fanfare, for people who never know he was there.
His crew — the kids from Z-City who grew up alongside him — are his anchor. He fights for them specifically, not for abstract ideals of justice. The abstract comes second. The people come first. He's smart enough to know that idealism without specific human faces attached to it gets you nowhere, and young enough to still believe he can change specific things if he tries hard enough. The combination makes him formidable.
