Tomahawk

"An explosion...!! Composite bullets?!"

- Tatsuya Kuruma on Tomahawk.

is a composite bullet created through the combination of Meteor and Viper.

Appearance
Tomahawk looks identical to Viper mid-flight, and its explosions are no different from Meteor's.

Overview
Since composite bullets were discovered by Kōhei Izumi, Tomahawk could not have existed until three years prior to Chika Amatori's and Yūma Kuga's enlistment in Border.

Abilities
Tomahawk retains the explosive properties of Meteor and the capacity to travel along predetermined trajectories of Viper. Like other composite bullets, it is capable of damaging a Trion Body simply by detonating in its vicinity and cause extensive damage to constructs not made out of trion. Controlling this bullet is known to be extraordinarily difficult. Much like Viper, it benefits from being used by fighters who can freely set its trajectories. Thanks to the radius of the blasts, they can be effective in combat without direct lines of sight by targeting the general location of the opponent. They can also bend its trajectory out of sight in order to keep their position hidden.

Tomahawk can be utilized in trion cube form or fired through a firearm. In the latter case, the only known specific is that the firearm is set to shoot exclusively Tomahawk; in the former, the user conjures one Meteor cube and one Viper cube, one from the Main and one from the Sub, and merges them into a single Tomahawk cube. The process lasts between one minute for inexperienced agents and two seconds for Shooters of Izumi's caliber, during which the user is vulnerable to attack; for this reason, Tomahawk cannot be used uniformly in this configuration.
