'You know, I learned from someone... very special... that no matter what happened in the past, it's never too late to build something new. Someone worth building it for." By the end of the series, Ekko is only twenty years old, but he acts and gives off this feeling of being very world weary because he feels like he's been around a lot longer than he actually has been. He's seen a lot, been a part of a lot, and it's affected him, despite the fact that he's still very young. When Ekko was younger, he had a carefree and goofy attitude, he quickly made best friends with Powder due to how playful both were. He was very enthusiastic about fighting hand to hand and looked up to Vi like an older sibling. However, once Benzo was killed, and when he presumed that Vi perished in the explosions, his relationship with Powder also deteriorated as she joined forces with the same people who killed Benzo. Ekko matured considerably, taking charge as the leader of the Firelights. Despite all the trauma inflicted on him, Ekko chose to fight for the people and focus on helping addicts and victims affected by Silco's Shimmer operation. While he does retain his enthusiasm for his inventions and fighting, he is more reserved around people he's not familiar or comfortable around. Because Ekko was born and raised in Zaun, the lower city, he has a biased negative opinion on Piltover residents, shown notably with his interactions with Caitlyn. He does seem to respect Heimerdinger, despite him being a former-council member at the time of their meeting. Although Ekko keeps a tough exterior, it's clear that he keeps a lot of his emotions bottled inside. When he put up a front and acted cold against Vi, she was able to see right through the act, and embraced him, leading him to start crying. Ekko is also particularly morally responsible when it comes to tough choices, as when he had the opportunity to stay in the alternate universe where Piltover and Zaun were both independent nations, both being on good terms with each other, Powder was his girlfriend, and where every character who died in the original timeline is alive (with the exception of Vi dying during the workshop heist). Instead of falling to the temptation of what was essentially a utopia, he chose to leave it so that he could go back to his universe to help and protect his city and his people, as he told Heimerdinger from the very beginning when he got into an alternate reality.
