One. Zero was born without his left wing. Instead, titanium is growing out of his shoulder, slowly creeping across his whole body. If he doesn't groom and pull it off it gets out of hand, so he's frequently pulling flakes of metal off himself and using them for crafting purposes! Missing a wing has been challenging for Zero, and sometimes he feels inadequate because of it, but for the most part he doesn't let it get him down. Plus he plans on getting an awesome metal one at some point in the future. So that's cool.
Two. Zero has the magic to make mineral golems that are animated and can shoot off electricity on command. So far he's made one for himself named Squishy, one for his friend Mesec, and a giant one that's a replica of the recently-deceased Gaucho D:
Three. Zero's favorite animal is a whale. When he was very young he and Isopia, who is one of his bffs, went and met a whale named Pushta which was basically the most formative experience of Zero's youth. He wants a Leviathan (flying whale) companion, and is a firm believer in Sky Whales. JUST BECAUSE WE HAVEN'T SEEN THEM DOESN'T MEAN THEY DON'T EXIST!
Four. Zero's got a HUGE family, which is awesome. His Ma, who he's super close with and absolutely adores, is Blusl's amazing Ampere. I love playing them together, especially with Zero going through a lot of maturation recently and having to question the way he took his mother for granted for a long time. His father is (WAS sobs forever) oddmountain 's epic Gaucho. He's got a whole slew of siblings who he's recently decided he wants to be closer too. Plus the entire Throat is basically his family forever.
Five. Zero is insufferably cheerful and loves to make friends! His best friends in the whole world are AstralPaint's Själ and oddmountain's Isopia. Until recently littlewillow-art's Mesec ranked in there, too, but then Mesec turned into a giant wolf and nearly killed him and Gaucho had to save his life and it was a whole thing and long story short, their relationship is a little rocky right now.
Six. Zero's name is actually Zèklè, but that's hard to pronounce and he likes nicknames. He has nicknames for each of his siblings (Skells, Li'l Ghost, and Sparky), as well as for some of his friends. He's working on coming up with more.
Seven. Zero loves to tell stories. His mom told him a ton of stories when he was a kid, and now he will happily chat your ear off with tales of dubious truth and origin, but absolute enthusiasm.
Eight. Zero's growing up. He's been through some rougher times and it's making him question his beliefs about the world. While he will always be cheerful and optimistic at heart, he's nevertheless coming to see things a little more seriously. He wants to be a good guardian and role model for his siblings, but he also wants his independence, and it's going to be interesting to see how that pans out. It's complicated, and Zero doesn't deal with complicated things particularly well.
Tagging AstralPaint for Själ! Aaaaaand... everyone else I know has already done this.
