Professor is a diminutive, aged robot engineered with extraordinary intellect and scientific mastery, serving as the team’s chief strategist and advisor. Crafted by Dr. Polto to safeguard and raise Robin after the youth’s parents were abducted, he embodies a paternal role, blending firm mentorship with an undercurrent of compassion.

His compact mechanical frame belies advanced cognitive prowess, while his personality exudes a mix of intellectual arrogance and endearing clumsiness. He frequently clashes in witty disputes with Bell, a radar-equipped feline robot, showcasing impatience and pride that counterbalance with authentic investment in the team’s welfare.

Operationally, Professor masters hacking, tactical orchestration, and scientific diagnostics, commanding missions during Robin’s absences. Beyond combat strategy, he maintains the group’s technological infrastructure and repairs their equipment. A critical partnership binds him to Benkei, a larger automaton who houses him during operations and sustains his energy via a symbolic "breastfeeding" interface, cementing their mutual dependency.

Origins trace to Professor’s pivotal role in Robin’s maturation, assuming guardianship from infancy onward. This shared history forges a bond rooted in respect, occasionally strained by his exacting standards. His layered persona surfaces through nuanced actions—quietly expressed relief at teammates’ survival betraying depths beneath his metallic exterior.

The character maintains narrative coherence across appearances, balancing cerebral command with lighthearted friction. Core attributes persist unaltered: razor-sharp intellect, unwavering protective instincts, and perpetually sparking rivalry with Bell define his enduring essence.
