Dynamo Roller

The Dynamo Roller is a main weapon in Splatoon and Splatoon 2.

The Dynamo Roller can cover turf while in motion and can fling a large amount of ink at medium range. Compared to the Splat Roller, this roller is much slower but covers a larger area while rolling and throwing ink. It has the greatest range of all the roller class weapons, but sacrifices speed; it rolls slowly when pushed, and it takes over a second to fling ink. The slow ink-flinging windup animation leaves the player vulnerable when attacking, as no other actions may be performed while readying the fling, and it is not possible to cancel a fling once initiated. The Dynamo Roller's weight class is Heavy, so mobility will be impaired when it is equipped, even when not attacking with the weapon.

Splatoon
The Dynamo Roller comes in a set with the Sprinkler and Echolocator. It can only be purchased after collecting the Sunken Scroll from the mission Enter the Octobot King!. Each flick of the weapon consumes 20% of the ink tank capacity, allowing for 5 flings before needing to refill on ink.

Splatoon 2
The Dynamo Roller returns in Splatoon 2, with an minor appearance changes but significant performance changes. It comes with the Ink Mine and Sting Ray. Each flick consumes 18% of the ink tank capacity, allowing for 5 flings before needing to refill on ink. Jumping before flinging ink will perform a long-range attack, the vertical swing. The vertical swing paints a long path of ink and damages distant opponents. If it hits, the vertical fling will kill a Steelhead in only one shot.
