Spectro serves as the central processor and analytical mind of the trio. 

In the comics, he is often portrayed as the one who interprets visual data and determines its strategic value. 

Cold and methodical, Spectro embodies the Decepticon philosophy of turning information into tactical advantage.

Capabilities:

• Coordination of combined camera mode

• Data processing and visual analysis

• Strategic interpretation of reconnaissance data

Spyglass is the primary sensor and perception specialist, responsible for capturing images and tracking targets. 

He is the most outward-focused of the three, constantly scanning the battlefield for useful intelligence.

Detached and observant, Spyglass is focused almost entirely on his function, showing little interest in combat beyond its value for gathering data.

Capabilities:

• Environmental scanning

• Long-range visual tracking

• Target acquisition and surveillance

Viewfinder acts as the memory bank and recorder, storing and relaying captured data back to Decepticon command. - often to leaders like Megatron or intelligence officers such as Soundwave.

Quiet and dutiful, Viewfinder is the least expressive of the trio, functioning almost like a living storage device with unwavering reliability.

Capabilities:

• Data storage and playback

• Integration with Decepticon communication systems

• Transmission of recorded intelligence

When united, the three form a working camera, capable of capturing high-resolution images for propaganda, espionage and battlefield analysis. 

This unusual alt-mode reflects their true purpose: not frontline combat, but information dominance - a crucial advantage in the Decepticon war effort.
