Advertisement anime casetify


Simon, also known as “The Digger”, is the protagonist of the anime series Tengen Toppa Gurren Lagann. At the beginning of the series, Simon is portrayed as a small and unassuming fourteen-year-old boy. He has a shy and introverted personality and often lacks confidence in himself. Simon’s experiences growing up in the village of Jiiha, where he was ignored by adults and shunned by his peers, contributed to his low self-esteem and cowardly tendencies.
However, as the story progresses, Simon undergoes significant character development. He gradually gains courage and confidence, transforming into a determined and resilient individual. Simon’s loyalty and unwavering devotion to his friends, especially his admiration for Kamina, play a crucial role in shaping his personality throughout the series.


Simon was born and raised in the village of Jiiha. Tragically, when he was seven years old, his parents were killed in an underground avalanche caused by an earthquake. This traumatic event instilled in Simon a deep fear and resentment of living underground. As a result, he developed a close bond with Kamina, an older boy who shared his desire to escape the underground and explore the surface world.
Simon’s role in the village involved digging tunnels and expanding Jiiha Village’s underground network. Despite being skilled at his work, Simon was largely overlooked by the adults and ostracized by his peers. This contributed to his feelings of insignificance and isolation.


Simon is initially depicted as a short and slender teenager with messy brown hair and small, shy eyes. He wears a simple outfit consisting of a white shirt, brown shorts, and a pair of boots. However, as the series progresses and several years pass, Simon undergoes a physical transformation. In the second half of the series, he becomes a twenty-one-year-old man with a taller stature, a broader build, and longer hair.


Simon’s most notable ability is his exceptional skill as an excavator. He has a natural talent for digging tunnels and caves, which is highly valued in his community. Simon’s skill as a digger allows him to contribute to the expansion and development of Jiiha Village.
In addition, Simon becomes the pilot of the Lagann, a powerful mecha robot discovered beneath the surface. With the Lagann, Simon gains the ability to engage in intense combat against various enemies, using the robot’s weapons and abilities to protect his friends and fight for their cause.


Simon’s journey begins when he discovers a small drill-shaped object and unearths a mysterious face-shaped structure. The face turns out to be a miniature mecha called Lagann, which Simon activates with the drill. With the help of Lagann, Simon emerges from the underground and embarks on an epic adventure to fight the oppressive Spiral King and free humanity from its subterranean existence.
Throughout the series, Simon’s determination and indomitable spirit inspire others to join his cause and form Team Gurren. Simon’s growth from a shy and insecure boy to a brave and influential leader is a central theme in Tengen Toppa Gurren Lagann, highlighting the power of belief and the ability to overcome obstacles.
