|First Appearance||Splatoon (2015)|
| Shielded Twintacle Octotrooper|
Twintacle Octotroopers are secondary soldiers of the Octarian army, and a subspecies of Octotroopers. They are a more aggressive variant that not only shoots quicker bullets of Octarian ink, but also fires repeatedly to its target, leaving them splatted if they don't watch out.
Twintacle Octotroopers look similar to regular Octotroopers: both being red on the back with white suction cups, and having a white bellyside, as well as small, thin legs and black boots. Unlike the normal Octotroopers, though, Twintacle Octotroopers have their tentacles split up in two, as their name implies. They also sport a more scowling face, with their large eyes squinting glaringly.
Both tentacle tips can be used as hands. They use at least one to control the vehicle they stand on.
The device they ride on largely remains the same as that of a regular Octotrooper and also have both stationary and mobile variants. However, its dashboard now also sports a large lime green button, on which the Twintacle Octarian's other tentacle rests on and appears to let it shoot repeatedly in the first place.
