Silver Iczel serves as Kawai Kawai's robotic partner, synchronizing with her to form the Silver Iczelion combat unit. This entity embodies a calm and gentle personality, mirroring Kawai's own demeanor. Its designation as Silver Type distinguishes it from other Iczel units such as Black, Gold, and Normal Type.

In battle, Silver Iczel grants Kawai the power to project defensive barriers. The primary offensive weapons unleashed through their synchronization are dual beam boomerangs, functioning as ranged projectiles. An additional specialized combat asset is a single forearm-mounted beam cutter. Their synchronization also grants access to the Burst Teleport Mode, enabling swift short-distance evasion maneuvers during combat.

Narratively, Silver Iczel fights alongside Kawai in pivotal battles against the Void entities dispatched by Chaos and Cross. During these confrontations, it aids Kawai in eliminating her designated Void opponent. The unit's combat approach emphasizes tactical defense and precision strikes over aggressive assault, aligning with its operator's composed warfare style. Silver Iczel's technological roots lie with the Iczer race, creators of these robotic systems specifically designed to bond with human partners and defend planets against mechanical life forms emerging from Big Gold's malevolent influence.
