Appearance

Splatoon Info

Iso is a very charismatic and suave octoling with a rather checkered history. He’s very intense and serious, and a typical frequent of Inkopolis might find him a bit imposing. Since he spent at least half of his entire life in the Deepsea Metro, he has a sort of high-strung disposition. He’s ambitious and hard-working, and he has a good sized handful of credentials to his name from history of work and ranks underground.

Personality

In his neutral state, Iso is calm and composed. When talking to strangers, he prefers to be polite, but to also keep his distance as much as possible. To most people he knows, he’s rather cold and unapproachable while still maintaining a facade of coolness and tolerance. In reality, he doesn’t care much for others, and he finds himself running out of patience when interacting with anyone.

Due to Iso’s trauma related to the sudden murder of his parents, he developed sociopathy in his earlier years following the event. This led to him being less concerned with the well-being of those around him, and he found that lying and manipulating others for the sake of self preservation came naturally to him. Despite this, he’s still very capable of loving and caring for other people. He just tends to be indifferent to the vast majority of people.

While still being considered impatient and a little quick to anger, it will take a sizeable heap of pestering for Iso to become genuinely enraged. Yes, he is irritable, but he deeply understands and prioritizes the art of decorum, so his cool and collected front will stay up.

• Iso has a special sort of spiritual link with the special weapon Booyah Bomb, which allows him limited usage of unique abilities related to it (e.g. ink telekinesis, Booyah Bomb activation without a weapon, etc.)
• Regarding his ink telekinesis ability, it takes a considerable amount of energy and sometimes even physical pain to harness his own ink telekinetically; this ability is fairly limited. Additionally, if his ink were to somehow get into the system of another octoling or inkling, he’s able to partially control and communicate telepathially with the “host” of sorts
• The origins of Iso’s long eye masks is unknown. His “deformity,” as Iso harshly puts it, is part of the reason why he sought out neuroscience as his career. He hoped he could find some solution in his studies as to why he developed such marks while in development

Infancy

Iso could be described as a happy and friendly little guy. He was charming and had a particular tendency to generosity. His parents took good care of him and loved him dearly.

• Age 0 - Iso is born to two unnamed Octarians
• Age 3 - Maggot is born to the same parents

Childhood

His behavior as a child was mostly the same—if not identical—to how he behaved as a toddler. He was kind and good-spririted and especially generous and loving. He loved to be the “big brother” figure for Maggot when he got old enough to fill that role for him. At age 11, everything started to change for Iso.

• Age 11 - bullying started

Adolescence

Not long after the bullying began, Iso did not take it well. He would have frequent tearful outbursts and lash out at his family despite his previously noble family man attitude. His personality completely shifted the second the harassment skyrocketed and refused to settle down. He quickly became cold and callous to loved ones or the few who felt concern for him. He instead pushed everyone away and make consistent efforts to isolate himself from others. Upon mastery of his weapon of choice, his behavior became more erratic with an extra pinch of aggression and hatred.

Young Adulthood

Soon after his escape, his intense mindset and outlook on life started to soften. Although the trauma inflicted by the bullies remained, his neurotic behavior mellowed with age and exposure to a far more pleasant environment, that being Inkopolis. He continued to improve mentally after meeting Natasha and starting a family with her later on.

• Age 18 - escaped the deepsea metro and approached Inkopolis
• Age 19 - married Natasha
• Age 20 - Natasha had their first son, Mano

Adulthood

Despite his self rehabilitation over the years, he remained mostly closed off from other people and rather reserved despite his personality as a young child prior to exposure to his bullies. He was a wonderful child to his children before he was captured by the Octarians, and his mental health once again rapidly deteriorated upon returning there.
