Here are some reasons why he might be perceived as a guardian:
* Loyalty to Autobots and humans: Bumblebee is fiercely loyal to the Autobots and often puts himself in danger to protect them. He also develops a strong bond with humans, especially in the live-action films, and often acts as a protector for them.
* Protective instincts: Bumblebee's actions often demonstrate a natural instinct to protect others. He will defend those he cares about, even if it means putting himself at risk.
* Acts of heroism: Bumblebee consistently performs acts of heroism, rescuing people and helping to save the world from the Decepticons. His courage and bravery make him a protector figure.
* Symbolic representation: In the Transformers universe, Bumblebee is often portrayed as a symbol of hope and optimism. He inspires others with his resilience and determination, acting as a guiding force for both Autobots and humans.
While not officially a "guardian," Bumblebee embodies the qualities and actions associated with a protector, making him a beloved and inspiring figure in the Transformers franchise.
