Indigo was a female SeaWing that appeared in Darkstalker. She was a childhood friend of Fathom. Later they fell in love, but were separated after the massacre. When Fathom was sent to the Night Kingdom to teach Darkstalker about the dangers of animus magic, Indigo went with him as a bodyguard. They got together again and then ran away to an island off the coast of the Rainforest Kingdom. Her mother had been in Queen Lagoon's army, where she would then become close friends with Princess Manta before she died. Indigo's father curated the museum at the Island Palace, and was quite happy to leave his only dragonet to the upbringing to the caretakers who'd been assigned to Fathom and Pearl.
She had dark purple eyes that were the same color as her seaweed necklace, which is purple. Her scales were a deep purplish-blue (more purple than blue) and she had the opposite color of claws (more blue than purple), hence her name, Indigo. At the Royal family gathering, where Albatross massacred most of the family, she wore a pearl necklace and bracelet with different shades of pink that ranged from almost white to deep rose. The necklace belonged to Pearl, but Pearl hated it because she hated things that weren't even and symmetrical.
In the first chapter, Indigo was fooling around when she was supposed to be sitting on the beach and waiting for the animus test to begin. She constantly teased Fathom and challenged him to disobey orders. Queen Lagoon and Prince Albatross appeared and scolded her but she talked back, despite her fear of the disapproving queen. Queen Lagoon treated Indigo unfairly and similar to a slave because Indigo had no royal blood. When Fathom politely asked the coconut to hit Albatross, she teased him yet again, possibly motivating him to reveal his animus abilities. When she saw what he could do, she was flabbergasted. She asked why he had never told her about his powers, to which Fathom responded that he didn't know he had them.
Later, while she, Fathom, and Pearl were at tutoring, Albatross sent a messenger for Fathom. Not wanting to leave his side, Indigo snuck away to watch what they were doing. Albatross discovered her spying on them and threatened to punish her.
Indigo was read about in a scroll by Turtle. The scroll was about her saving the tribe from a deranged killer, Albatross, that massacred almost the entire royal family.
Throughout their whole lives, Fathom has shown great compassion for her along with her returning the same. Due to her bond with Fathom, she was invited to royal family gatherings despite being the only one there without a drop of royal blood. When Albatross went mad after using too much animus magic, she refused to let him kill Fathom. Although in the end she survived, she was ready to sacrifice herself to distract Albatross.
When Fathom was sent to the Night Kingdom by Pearl, Indigo volunteered to go with him as a bodyguard. Although Pearl disapproved, she had to let Indigo go since Indigo was a hero to the tribe. Indigo was very protective of Fathom when they were in the Night Kingdom, as shown when Indigo nearly killed Clearsight when she embraced Fathom, because she feared Darkstalker trying to use his magic on Fathom and on anyone Fathom cared about deeply. She also became very suspicious around Darkstalker.
Later, she smashed an enchanted goblet that Darkstalker gave to Fathom as a gift which angered Darkstalker and disappointed Fathom, since he didn't know it was charmed. After being enchanted by Darkstalker into a wooden dragon figure, she was then "brought back to life" by Fathom. She told him she doesn't care if he is an animus at all as long as he uses his powers for good. By five years after Darkstalker was enchanted to eternal sleep, she had three dragonets with Fathom. She and her family lived on a deserted island away from the Sea Kingdom's palaces.
Almost immediately after meeting Darkstalker, Indigo did not trust him and often thought of him in a similar way to Albatross. She almost kills him not too long after their first introduction. She was eventually trapped in a dragon carving by Darkstalker, and she was stuck there until near the end of the book where Fathom used his animus magic to free her.
For a majority of her life, Indigo and Pearl had a sisterly relationship, with Pearl always helping her to fit in among the royals. However, after the death of Albatross, Indigo was promoted to Pearl's Honor guard and Fathom was ordered to stay away from her. Separating Indigo from her beloved Fathom chilled the relationship between Pearl and Indigo.
"Using your magic doesn't make you evil, Fathom! Doing evil things makes you evil! Have you done anything evil lately?" - About Fathom saying animus magic itself is evil.
"...Our choices are what make us good or evil - what we do, how we help or hurt the world. You make the world a better place by being in it. With or without your magic, that's always been true."
"He's too dangerous...He's already trying to mess with your head, can't you tell? This isn't safe, Fathom. I should kill him right now, to protect everyone."
"I look like a squid pretending to be a seahorse."
"You didn't just eat it! You were smug about it! You totally deserved to be dumped in the koi pond!"
"He's clearly a Blob. Aren't you, Blob?" - To Blob.
"I know. You don't have to be so weird about it though."
"It's true. He's really never coming back. You did the right thing, Fathom. You saved Pyrrhia from him forever. It's safe to be happy."
"Those pillows will never question your authority again." - After Fathom punched some poor, innocent pillows out of anger.
"Stop smushing each other into the sand and I'll tell you a story." - To her fighting dragonets.
"Ah, well, there's your mistake. You forgot one of the waits." - To Clearpool when she complained that she couldn't catch the fish.
