Hero Shot

The Hero Shot is a shooter in Splatoon and Splatoon 2 that is exclusively used in single player modes.

Splatoon
The Hero Shot is a futuristic weapon with a black and lime green color scheme and many glowing lights that leave a small trail as Agent 3 moves. It is used exclusively in the Octo Valley single player and the Inkling Squid amiibo challenges It behaves similarly to the Splattershot, with decent range, accuracy, fire rate, and damage. It's the only weapon in the game with multiple switchable sub weapons, (Splat Bombs, Burst Bombs and Seekers), however only the Splat bombs are usable during the Inking Squid amiibo challenges. Its fire rate can be upgraded with Power Eggs found in Octo Valley missions. Beating all amiibo missions unlocks the Hero Shot Replica for purchase at Ammo Knights. These upgrades have no effect during the amiibo challenges.
 * No upgrades: Blue lights
 * One upgrade: Purple lights
 * Two upgrades: Yellow lights
 * Three upgrades: Green lights

Splatoon 2
The Hero Shot in Splatoon 2 is majorly redesigned, and is now a more longer, angular design that bears little resemblance to the original or the Splattershot. It now comes with switchable sub weapons of Splat Bombs, Curling Bombs and Autobombs, however every other Hero weapon also has these. It is now only upgradable twice, while the other Hero weapons can be upgraded once. Completing all missions in Octo Canyon with this weapon unlocks the Hero Shot Replica for purchase from Ammo Knights.
 * Lv.1: Primarily yellow
 * Lv.2: Now primarily orange, with an extra handle and an attachment near the nozzle, requires 800 Power Eggs and 2 Sardinium. Increases fire rate. Watch your ink consumption!
 * Lv.3 Now once again primarily yellow, with an extra attachment at the back of the gun, requires 1500 Power Eggs and 3 Sardinium. Increases fire rate. Watch your ink consumption!

Hero Shot Replica
The Hero Shot Replica is a reward in Splatoon and Splatoon 2 unlocked through various means. It is a shooter-type main weapon and is visually identical to the Hero Shot. Despite its unique appearance, it is simply a reskin of the Splattershot from that game, sharing the same stats and loadout, sub weapon and special weapon.

Trivia
