Seeshell

Seeshell, originally an outdated C7 Probe from Babylonia, frequently used in ocean exploration and climate observation. Its capability is recognized after multiple CUB experiments, and it is now active in the field as a CUB.
When transformed, Seeshell's four cannons can provide substantial support fire. The two fisheye lenses by its sides also offer a comprehensive view of the battlefield. By syncing those data to Constructs and the commandant in real time, Seeshell is valuable for evaluating the battle.

Due to the frequent accidents that occurred during the C7 Probes' exploration missions, an engineer tries to install multiple modules on a prototype to increase its mission success rate. However, the large number of modules and their intricate connections make it impossible to mass produce.
As the C7 models are retired, the prototype is going to be decommissioned as well. But, during the CUB program, its outstanding damage output and scouting capability caught tester's attention, who then named it "Seeshell".

Seeshell's appearance is the best demonstration of its abilities.
Everything it sees and records during an ocean exploration is gathered inside its "shell."
Every time it extracts those valuable data, researchers are astonished by the mysteries of the deep sea contained in its pearl.
It has been recording, watching, and gathering those scattered fragments to create these pearls to help study the ocean. Now, it will observe the battlefield and help its warriors shine.
