Squidbeak Splatoon

The Squidbeak Splatoon was a platoon of soldiers who fought against the Octarians during the Great Turf War. It was led by Cap'n Cuttlefish, and its members included Ammoses Shellendorf, Judd, a male Inkling, and a female Inkling. The group used Bamboozlers in combat.

Members

 * Cap'n Cuttlefish- Cap'n Cuttlefish was the leader of the Squidbeak Splatoon. He wore the original Legendary Cap, along with a button-down shirt, khaki pants, a belt, and boots. His shirt was adorned with three medals of unknown value.
 * Ammoses Shellendorf- Ammoses Shellendorf was a member of the Squidbeak Splatoon. He was a horseshoe crab who excelled in designing weapons, and likely designed the original Bamboozler used during the Great Turf War. He is also the grandfather of Sheldon, who currently manages Ammo Knights.
 * Judd- Judd was a feline member of the Squidbeak Splatoon who presumably joined after he was awakened from his cryogenic slumber. His exact function in the platoon remains unknown, as he does not appear to be able to manage a weapon. Judd currently judges matches of Turf War and Ranked Battle, and can often be seen sleeping on a pillow in Inkopolis Plaza.
 * Male Inkling- This Squidbeak Splatoon member's identity is unknown. He can be seen in Sunken Scroll 15 wearing an Ink Tank on his back.
 * Female Inkling- This Squidbeak Splatoon member's identity is unknown. She can be seen in Sunken Scroll 15 leaning against a rock.

New Squidbeak Splatoon
The New Squidbeak Splatoon was formed by Cap'n Cuttlefish after the Great Zapfish was stolen by the Octarians. He recruited his granddaughters, Callie and Marie, into the platoon to search for the missing Zapfish, and later persuaded Agent 3 to join the platoon as well. The New Squidbeak Splatoon successfully defeated the Great Octoweapons and DJ Octavio on two different occasions, recapturing the stolen Zapfish and restoring power to Inkopolis.

Members

 * Cap'n Cuttlefish- Cap'n Cuttlefish is the leader of the New Squidbeak Splatoon. He resides in a small shack in Octo Valley, wearing tattered clothing and a ragged Legendary Cap. In Octo Expansion he has a new look, wearing a new white hat, a tracksuit with headphones and some slip-ons, where he guides Agent 8 through to get back to Inkopolis.
 * Agent 1- Agent 1, or Callie, is a member of the New Squidbeak Splatoon. She wears a pink beanie decorated with a large golden star, a pink sweatshirt, and sunglasses to conceal her identity. Agent 1 is the cousin of Agent 2. In the final boss battle, Agents 1 and 2 hijack DJ Octavio's transmission and play Calamari Inkantation, allowing Cap'n Cuttlefish to escape. Agent 1 is never directly seen in Octo Valley (mode); she is only acknowledged through Cap'n Cuttlefish's monologues and DJ Octavio's radio transmissions. In Octo Canyon (mode) she is kidnapped and mind-controlled with "hypnoshades" by DJ Octavio, assisting him during the final boss battle. She is rescued and appears after beating the final boss.
 * Agent 2- Agent 2, or Marie, is a member of the New Squidbeak Splatoon. She wears a green hat embroidered with an orange emblem, a green shirt, and a surgical mask to conceal her identity. Agent 2 is the cousin of Agent 1. In the final boss battle, Agents 1 and 2 hijack DJ Octavio's transmission and play Calamari Inkantation, allowing Cap'n Cuttlefish to escape. Agent 2 is never directly seen; she is only acknowledged through Cap'n Cuttlefish's monologues and DJ Octavio's radio transmissions. In Octo Canyon (mode) she guides Agent 4 throughout the missions and appears during the final boss battle, where Marie tries to free Callie from the mind-control.
 * Agent 3- Agent 3, or the player character in Splatoon, is a member of the New Squidbeak Splatoon. They entered Octo Valley through a grate in Inkopolis Plaza, and were immediately greeted by Cap'n Cuttlefish, who gave them the Hero Suit. While donning the Hero Suit, a hand-me-down from Agents 1 and 2, Agent 3 is instructed to traverse the underground Octarian bases in Octo Valley through devices called Kettles. Agent 3 defeated the Great Octoweapons and DJ Octavio, recapturing stolen Zapfish and, eventually, the Great Zapfish along the way.
 * Agent 4- Agent 4, or the player character in Splatoon 2 is the newest member of the New Squidbeak Splatoon. They entered Octo Canyon through a grate in Inkopolis Square, and promptly met Marie, who gave them the new Hero Suit and entrusted them with finding the missing Great Zapfish and Callie. Making their way through the Octarians' new base, Agent 4 eventually found and defeated DJ Octavio, freeing Callie from his mind control and rescuing the Great Zapfish.
 * Sheldon- Sheldon was invited to be a part of the New Squidbeak Splatoon in Splatoon 2, where he lends Agent 4 several Hero weapons. He also comments during missions, giving advice to Agent 4. In the final boss he is seen driving a flying truck with Marie on top, reminiscent of the trucks used during Splatoon's Splatfests.
 * Agent 8- The first Octoling member of the New Squidbeak Splatoon, recruited by Cap'n Cuttlefish when he, Agent 8, and Agent 3 were knocked into the Deepsea Metro. Agent 8 is able to escape the depths with the help of Off the Hook and later saves Inkopolis from being destroyed by the AI Commander Tartar. Agent 8 was formerly working under the Octarians before leaving under the influence of the Calamari Inkantation; a misunderstanding led him to fight Agent 3 before the two agents and Cap'n Cuttlefish were knocked into the Deepsea Metro by an unknown attacker.

Trivia

 * The Squidbeak Splatoon is likely the reason Splatoon is named as such.
 * Splatoon is a portmanteau of splat and platoon.
 * If the player talks to Marie in Splatoon 2 for too long she might mention that she might have go and look for an Agent 5.
 * In one of the conversations the Squid Sisters have at the cabin in Tentakeel Outpost Marie mentions that she was recruited by Callie to the New Squidbeak Splatoon.
 * Agent 8 isn't confirmed to be the 8th member recruited to the New Squidbeak Splatoon, but got the name as a nickname from them being identified as Subject No. 10008 in the facility at the Deepsea Metro.
