Octoshot

The Octoshot is a shooter used exclusively by the Octolings during the Octo Valley missions as well as by Agent 8 in Octo Expansion.

Description
The Octoshot is a weapon with a that resembles a sleeker, more metallic Splattershot. It behaves similarly to the Splattershot, and comes with Splat bombs. It is only ever seen used with purple ink, the signature color of the Octarians.

Octo Expansion
The Octoshot returns in the Octo Expansion where Agent 8 finds it as canned item along with the Splat Bombs as they make their escape to the Promised Land. It now has pink ink when retrieved and has blue ink during the boss fight with Agent 3 after the player completes all the tests.

Octoshot Replica
The Octoshot Replica is a reward from Judd for reaching Level 45. It is a shooter-type main weapon and is visually identical to the Octoshot. Despite its unique appearance, it is simply a reskin of the Tentatek Splattershot, sharing the same stats and loadout, with Suction Bombs as its sub weapon and the Inkzooka as its special weapon. In Splatoon 2, the player receives it as a reward for completing Octo Expansion and has yet again the same stats and abilities of the Tentatek Splattershot with Splat Bombs and Inkjet.

Trivia

 * It is the only weapon in the game that cannot be used in any way by the player in Splatoon. Octo Expansion however, lets Agent 8 use it.
 * Despite the Octarians only being seen using Splat bombs, the fact the replica has Suction Bombs suggests that the Octoshot also has switchable sub weapons like the Hero Shot.
 * The Octoshot bears a resemblance to the real-life IMI Uzi submachine gun.
