Oh boy, oh boy. Be prepared for a long-ass rant.
got me into the game before I even realized what League of Legends was. That and my friends/boyfriend invited me to play, but I've seen Vi around a lot on the Internet beforehand and was immediately hooked on her character.
I'm a huge sucker for people who are tough on the outside but complete softies/do-gooders at heart. I loved the complexity of Vi's character past her punching - the fact that she used to be a criminal and had a change of heart at such a young age meant that she wasn't inherently malicious, she was probably sticking with the group to scrape by and survive. She's a kid prodigy at hextech, while at the same time being physically powerful enough to defend herself/fight even without her gauntlets. And let's face it, she probably has the worst best fashion sense in all of Runeterra (srsly rito do you know how much of a pain it is to cosplay Vi with like her half-tutu-thing and her backpack and her boots wheredidsheevengetthemfrom)
Jokes aside, I think Vi's super underrated when not viewed from the perspective of her rivalry with Jinx. She's headstrong, stubborn, overconfident and cocky, but also actively trying to reform and atone for her past - besides being part of the Piltover PD she's seen with a lollipop in her concept art, which I headcanon as being one of her coping mechanisms for weaning off her habit of smoking, which shows how much she wants to change. Even her fashion sense says something about her - she's most likely scrapped together all that armor by herself, and they seem to be worn in places where she must've had been injured before (for example, the knee protector on one knee and the brace on the other - I like to think that she injured herself from her left knee down and didn't want it to happen to her other leg). That to me is character development.
One thing that gets me is how Ekko's voice lines hint at some expanded backstory on Vi. I think Gypsylord mentioned that due to trauma in her childhood she has amnesia (though I don't know from which point on, because she doesn't seem to remember Jinx and that they're both sisters cough), which when coupled with how Ekko addresses her (as someone he looked up to once, was disappointed in, and as a Zaunite?????) makes for a very intriguing, colorful past...
I don't just love the living heck out of Vi, I identify with her as a character. She's got some battle scars, dude, but hell, she's fighting as much for a better tomorrow as Jayce is. I wish more people would appreciate her as she is beyond her relationship with Caitlyn/her rivalry with Jinx/her expanded rivalry with Ekko??? She feels more fleshed-out to me than the other champs in the game, or perhaps that's just because I'm biased towards the underdogs of society :P She's cocky and confident in her abilities, but she has her insecurities; she's actively trying to make herself a better person, but in her own way (though I don't doubt that Cait could be one of the reasons why); she's got a great sense of humor :D; and despite how much she teases Cait, she seems like the kind of friendly person anyone would warm up to (well, if they're not completely off their rockers like Jinx) judging from her lines for Cait and Jayce. Her lore isn't where her story ends; it's everything from her story to her lines to her character design to the way other characters interact with her that paint a picture of her as a person, not just another champ on the Rift. I feel like a lot of it is reduced to her identity as Jinx's rival after Jinx was released, and the "canon" lesbian in the League (that is still sexualized to some extent - like the boobs on her Officer skin and her skintight Neon Strike skin - but I think Debonair is a step in a better direction, though I've had enough of the community calling her a dyke and reducing her character to just that.)
Big kudos to Riot and Gypsylord for creating a character I genuinely care about and identify with, in a way I haven't felt about a fictional character in a long while. As a girl growing up loving games and presented with strong male archetypes as protagonists, Vi is a breath of fresh air and the depth of her character feels empowering. I do play a lot of Leona, Sejuani, Soraka, Diana, etc. but Vi is someone I can relate to - you can be female and punch faces in, you can be strong, and you can be smart, even if it's not the kind of "smart" that society would normally think of.
I didn't really get "into" the game until Debonair Vi came out (that's when I decided to say "fuck it" and drop my money on getting Vi and her skin, back when my account was level 10-15 or so), and since then I've been playing her top and jungle until my account was 30, and only then I've branched out and tried other champions (because I kept getting beaten in lane as toplane Vi lol). I don't play her as much anymore, and thanks to Mata's incredible showing at last year's Worlds I've taken a shining to the support role, but Vi continues to be my #1 favorite champ.
Once again thank you Riot and thank you Gypsy for making such an awesome character :D
