I want to know more about your 4
My Four is named Tater Tot! She/He! Thank you for leaving an ask showing interest, as I will now spout paragraphs at you!!!
She's a less-than-average student despite her dedication to academics, and isn't very good at socializing due to being "too loud" and "too annoying" for other inkfish to interact with her. Tater was also orphaned at a very young age, and has no idea who her parents are, but was raised alongside kids or adults who didn't like her presence for the above reasons. For all intensive purposes, she was a "problem child".
This eventually led to her suppressing herself, becoming quiet and still an average kid despite being so devoted to school. It was basically her life, and she wasn't even good at that.
When taken into the Squidbeak Splatoon by Marie, she'd heard all about Agent 3 from the Squid Sister and wished to be like them. Marie's praise was some of the first she's ever had that meant something to her, and it caused her to days a renewal in her passion. Even if she failed socially and academically, Tater was given a chance to do something good with her life by being an agent. And when the role of hero ended and Callie was saved? She received very little praise. No public recognition. So, she took the title of Hero and made that her entire personality. She'll be a hero to the people in one way or another!!
Tater, at one point or another, had a relationship with Junk, Agent 3. This lasted until after the events of Octo Expansion, where Junk had forgotten most things about their life- and thusly forgot about Tater. Agent 4 still tries to remind Agent 3 about their past together, and though Junk humors this sometimes, nothing good ever comes from it. Tater is heartbroken, but knows that a heroes must have happy endings. She's seen so in the books and shows she's indulged in!
She also has an unknowing rivalry with Agent 8, Guille. Guille dresses up as a mysterious, villainous figure named "Zoro" for reasons pertaining to their own story- but long story short, it's a "hero vs. villain rivalry" tale between the two that Tater made for her ego.
