Tri-Stringer

The unnamed bow is a main weapon in Splatoon 3.

Splatoon 3
The unnamed bow was initially shown in the announcement trailer of Splatoon 3.

It resembles a or a miniature, but made out of parts of a fishing rod, including a reel and string. When the Bow is fired, it launches three vertical projectiles of ink while jumping. The bow seems to be able to shoot horizontally, but only when standing, making it similar to the roller. You also seem to be able to charge up the bow before you fire it, similar to the charger. To fire the weapon, the Inkling or Octoling pulls back on the string, which changes color depending on your ink.
