―Ironmouse, about the Federation
Ironmouse, simply known as Mousey or Mouse, is a Puerto Rican and English-Speaking member of the QSMP. She was announced on August 25, 2023 and first joined on August 28, 2023.
She is portrayed by the content creator of the same name.
Personality
Mousey comes off friendly at first, but once she warms up to someone she gets even more charismatic and humorous. She can be paranoid and easily frightened on her own in an unfamiliar setting but grows braver and energetic with company, such as when adventuring with friends. Despite her own paranoia, Mouse can be effortlessly intimidating. She's easily drawn to mischief and and entertains most amusing situations to fulfil her desire for drama; these likely are due to her being a demon.
Mouse is transparent about being a demon and has never hesitated telling her peers about it, regardless of their reaction. She can sense other demons roaming the island and finds their attempts to hide their demonic identities amusing. This is not to say Mousey doesn't have her own secrets about herself, however.
Mousey finds the eggs adorable, often referring to them as "babies". She especially adores her daughter Empanada. Mousey's paranoia is even more apparent as she took on motherhood; though she's known to be mischievous among her friends, Mousey greatly tones it back around her egg. Her self-consciousness slips out more too, revealing her doubts as a mother or even overall person.
Since the islanders' return from Purgatory, Mouse has shown signs of repressing trauma, consistently denying Purgatory's real occurrence by calling it a nightmare that was all in their heads even when others tell her otherwise. During the first days back on Quesadilla Island, Mouse seemed disoriented and still in 'survival mode.'

Relationships
Family


Mouse grew attached to Empanada almost instantly. Initially Mouse had second thoughts about motherhood but she embraced the role right after anyway, unable to push the egg away moments into meeting her for the first time. Mousey turns out to be a doting mother, showering her daughter in praise constantly. Ever since the adoption, Mouse always starts her day on the island looking for Empanada, and she makes sure Em knows that even if she's very busy, Mousey is always thinking of her. All this affection is continuously reciprocated just as much by Empanada too.
If verbal affection wasn't enough, the two also enjoy giving each other many gifts and promises. Mouse has gone as far as to rename Hot Girl Beach to Empanada Beach and hand its ownership to her daughter, and she did so without hesitation.
Mouse's paranoia affects her parenting too; she panics at the slightest potential danger to her egg or when she loses sight of her for a second. On their first day together Mousey even ended up in tears from panic when Em fell off a dangerous height. Her self-consciousness as a parent is thus also clear as she often questions her ability to be a responsible mother.
Though most islanders know Mouse to be a demon, she formally revealed it to Em, fearing that might scare the egg - instead, Empanada casually accepted it, even finding it very cool.
Empanada's Co-Parents

Tina and Mouse gravitated towards each other from the day they arrived. They may be one of each other's closest friends but they butt heads when it comes to the subject of their demonic identities; Mousey tries her best to convince Tina that being a demon is not something to be ashamed, that it's not worth hiding from your loved ones and if anything it's something to be proud of but Tina has stayed firm and stubborn, consistently expressing immense shame. Mouse may not outright expose Tina's secret out of respect, but she does enjoy testing the limits of teasing about it in front of others, to Tina's horror.
They co-founded Girls' Village and continue to live as neighbours in Breakfast Village.

Jaiden and Mouse clicked well from the day they met, and Jaiden was one of few to introduce Mouse to Lucky Ducks. They co-founded and now live as neighbours at Girls' Village, spending a lot of time together alongside Foolish and Tina.
Mousey seems to highly respect and care for Jaiden. During Día de Muertos, Mouse made sure to spend time with and tell Bobby, Jaiden's deceased son, how much his mother loves him when Jaiden was unable to attend the event and reunite with him. Mouse even went out of her way to fulfil Jaiden's request to play a song to Bobby and stuck around longer than she planned to for the day just to be with him for Jaiden.
After Purgatory, Mousey has expressed missing Jaiden, who is currently MIA. She's also bashed Bad after he suspected some of the blood on him may have belonged to Jaiden from their time at Purgatory.

Niki gave Mousey a diamond on the day they first joined the island. After Niki said she's a cat, Mousey asked if she could give her a headpat. Niki said that she loved to interact with her and that she was very cute.

Ever since becoming co-parents, the two have bonded over their love for Empanada and began to care for each other too. They share similarities in their parenting like their paranoia and never-ending praising of Em. Mousey also appreciates and admires Bagi for her responsibility as a mother.
Together they swore revenge on the Eye Soldiers for taking their daughter's first life. After Bagi apologised for the incident, Mouse expressed her wholehearted trust in her co-parent, praising Bagi for doing her best to protect Em and reassuring her she's nowhere at fault.
Islanders

Foolish and Mouse have a shared desire for chaos. Mouse seems to understand his thought process and actions very well despite him confusing even his close friends. Still, Mouse takes any opportunity to tease him with the other islanders.
Despite multiple islanders trying to move into his Dragon, Mousey was the first to be offered by Foolish himself to live near him. This would eventually lead to the founding of Girl's Village.
Together, the two have gambled at lucky ducks and adventured out into dungeons multiple times. They also share a similar sense of humour, once having a laughing fit so intense it lasted over 15 minutes; Mouse coined it her "Sunbird" disease ever since.
Foolish has been subject to Mouse's more nefarious side though; he once offered her a chance to take part in caring for his child Leo after Mousey expressed wanting her own egg, before Purgatory. Instead, Mouse used this to accuse Foolish of not wanting his child, once going as far as to claim he didn’t even care his child was missing to his face.
Regardless, Foolish seems to not hold negative feelings towards Mouse about this. During Purgatory, after Green Ninjas' elimination, Foolish vouched for Mousey to join Team Bolas and was very enthused when she officially did.

Mousey was the first to be offered a tour of the island by Cellbit. He and Roier then took Mousey in and gave her a room in their castle.
Cellbit also warned Mouse to not trust the Federation, him believing it was the Federation that imprisoned her and the other new islanders.
Cellbit was very pleased when Mouse joined Bolas. At the end of Purgatory, Mouse expressed concerns about Cellbit's wellbeing after witnessing his short-lived reunion with his son at the end of Purgatory. She said she would help him kill all his enemies and assured him that she would be there for him whenever he needed.

Roier has a lot of fun with Mousey and has a lot of laughs with her, especially when she swears in Spanish. Cellbit and Roier took in Mousey and gave her a room in their castle.

Mousey and Bad are usually nice to each other, however, Mouse's chaotic personality clashes with Bad's more calm one, yet the two get along fine. She finds Bad's constant dancing around the topic of his species amusing, teasing him often. She also thinks he's a menace - like when he blew up her beach - though he makes up for it later - he cleaned it up and gave her a chest full of pink sand.
Recently, Mouse has expressed concerns over Bad's state, especially in regards to his memory loss. She relates to him regarding having bad memory, but his is at a severe level. Nevertheless, Mousey teases him about it and entertains his shenanigans.
Mouse, speaking with Empanada about Bad's state, called him her friend, saying he understood her and listened to her a lot. She said she expected nothing from him and just found him as a funny guy, talking of how they one time were up at 4AM, just the two of them, talking. She wants to help him, but doesnt know what the best course of action to do so is.

Mouse's first days on the island were mostly with the French as company, especially Antoine. He taught her various parts of French internet culture and showed her some parts of the island.
He and Baghera were the first to call her "Souris de Metal". This would become Mouse's official nickname amongst the French.

Mousey sees Etoiles as the island's protector. He was their to help protect her during her first day. Most of their interactions consist of him training her to fight better while also just hanging out as friends.

TBA

Slime and Mousey bonded while performing karaoke, particularly while singing "Bop to the Top" from High School Musical. Since then, they have expressed plans to create an actual cover together.
The two joke around well together, Mouse usually being left in tears from laughter after talking to him.

Pac and Mike tried to rob Mousey on their first encounter, only to find out she had no items. They helped her find her items and even gave her some blocks. They also showed their concrete farm to her so she can start building. Despite their odd first meeting, the three got along well together.

Felps hung out with Mousey on her first day. They talked about anime and did dungeons together.
Eggs


Richarlyson was the first egg Mouse encountered. He was seemingly a big fan of Mouse, seeking her out continuously, giving her gifts and asking to take her photo all during her first day; his father Cellbit even teased him about it. Mouse found Richarlyson to be rather cute and enjoyed interacting with him. She even claimed him as her favourite egg before Empanada's arrival.
While they do not have a mother-son relationship, Mousey stated she considers Richarlyson "part of the family", even that she'd kill for him like she would for her own Empanada.
Organizations

One of the first things Mousey learned upon arriving to Quesadilla Island was "to not trust the Federation". Cellbit informed her of his suspicions over the Federation being behind her imprisonment before he and the other islanders rescued her. Even after Foolish and Jaiden brushed his claims off as everyone having their own reasons to trust or not, Mousey stayed wary of the Federation. She'd even react unamused to their features, such as the Cucurucho Cookie system.

TBA

Though she started on a rival team, Mousey's relationship with members of Team Red never soured through Purgatory. If anything, she would express enjoying their company and would wear a gas mask - Bolas' signature - herself, despite not (yet) being in the team. Once her Green Team was eliminated, Mouse made it clear she favoured joining Bolas over Soulfire, and Bolas were just as eager to welcome Mouse in.
Though there were only a few days left into Purgatory, The few times she'd be present Mousey found herself indeed fitting right in with the chaotic team.
