|We're stronger than they are, but we can't stop them!!
— Omega thinking to herself in Volume 11 of the manga.
Omega is a female Inkling who wears Fake Contacts, ω-3 Tee, and Toni Kensa Black Hi-Tops. She has the "Banger" hairstyle and her main weapon is the Nautilus 47. Her hair color is aqua blue with a small amount of red at the tips of her tentacles, which is unique to her and her team. She also has a unique red eye color.
Omega has a quiet and serious personality, possibly due to being shy. She, like her teammates, became more compassionate after their battle with Team Blue.
- Omega has an ability that lets her sense other people's movements, which is known as X-Zone. It seems that only she and Vintage have this ability.
- She and Vintage are childhood friends.
- Omega likes to share her favorite songs from her favorite band to other people.
- Red-Soled wants Omega to wear cuter clothes, but she hasn't had the opportunity to take her shopping yet.
- When she sees Skull having fun in the Rainmaker battle against Team Blue, Omega is momentarily stunned as she knew Skull to be "so cold" in battle.
- In the bonus chapter, "Lost Property", Omega gifts the jellyfish extra tickets to a nearby concert bringing Strap, Clip-Ons, and Goggles as well.
