The Grizzco Charger is a weapon in Splatoon 2. It appears to be an illegally modified Bamboozler 14 Mk I. This weapon can only be used during Wildcard Rotation shifts in Salmon Run in Splatoon 2, and similarly in Salmon Run Next Wave in Splatoon 3, especially during Big Run.
The weapon is an instant charging Charger weapon with powerful shots and extremely long range (the same as the unscoped E-liter 4K). The weapon's charge speed is instantaneous and the damage it deals is higher than the Bamboozler by 135%, but is still lower than other chargers being unable to burst a Steelhead's bomb in one shot. Movement speed while charging is 20% higher than that of the Bamboozler. It cannot hold a charge. Its ink consumption is between the Goo Tuber's and the Splat Charger's, consuming 13% of the player's ink tank per shot. It's fast rate of fire due to its instantaneous charge can easily, if aimed properly, take out a Steelhead in a couple of shots at its ink bomb, and deal heavy damage, maybe even burst, the Booyah Bomb being charged by the Horrorboros, heavily damaging the King Salmonid in the process.
