Grasshop, whose full name is Larva P. Grasshop, is a character from the anime series Spider Riders: Yomigaeru Taiyou. He is an Invectid, a member of an insectoid race, and is specifically a grasshopper-type. His tall, dark-blue form is characteristic of his species. Initially, Grasshop holds a significant position as a member of the Big Four, a group of elite and powerful Invectid warriors tasked with retrieving the Oracle Keys for their leader, Lord Mantid. His appearance and rank are marked by a brown collar with gold lining and a cape, though his attire later becomes simpler after his fall from grace.

Despite his imposing rank as a villain, Grasshop is fundamentally a gentle and kind-hearted individual who loves children. His wife, Weeval, openly states that his promotion to the Big Four was a mistake, as his peaceful nature makes him ill-suited for combat and the cruelty expected of his station. Throughout his career as an antagonist, he sees little success in his missions against the Spider Riders, which leads to disdain and disappointment from his comrades. His motivations are not rooted in malice or a desire for power but in a wish to provide for and earn the pride of his family, which includes his wife and his children, Step and Jump.

Grasshop’s role in the story shifts dramatically from a recurring antagonist to a key ally. He is one of the first major Invectids to meet the protagonist, Hunter Steele, and his early attempts to defeat the Spider Riders are marked by failure. In a notable act of sabotage, he deliberately reveals the existence of the Oracle Keys to the Spider Riders to discredit a rival. After losing a crucial key and being blamed for this failure, he is expelled from the Big Four and banished to wander the Inner World. It is during this exile that his character arc truly begins. He vows revenge but soon finds his perspective changing when he crosses paths with Princess Sparkle of Arachna. She shows him unexpected kindness, forgiving his past actions and affectionately dubbing him Uncle Hop. This bond transforms Grasshop, softening his stance toward humans. He eventually becomes a traitor to the Invectids by helping the Spider Riders escape captivity. His most significant contribution to their cause is disabling a powerful Battle Beetles regeneration device, allowing Hunter to defeat it. His redemption culminates when he courageously confronts Lord Mantid, offering his own life in exchange for the Spider Riders safety, an act that cements his loyalty and goodness in the eyes of the protagonists.

Key relationships drive his development. His bond with Princess Sparkle is the most important; she sees the good in him from the start, and he becomes a protective, almost paternal figure to her. They travel together and become inseparable, with Sparkle even adopting some of his speech patterns. His relationship with his family, Weeval, Step, and Jump, is his primary motivation and his eventual reward, as he finally reunites with them after guiding the Spider Riders through the sewers. He also has a notable encounter with fellow Big Four member Beerain, whom he tends to after she is wounded, urging her to see that coexistence with humans is possible.

In terms of notable abilities, Grasshop is proficient with various technological devices, preferring to use his inventions to fight rather than engaging in direct physical confrontation. He is often reluctant to battle personally, sending minions to do the work for him. Despite being a grasshopper-type Invectid, he ironically claims to be afraid of heights. His knowledge of the Invectid citadels infrastructure, including hidden sewer routes, proves invaluable to the heroes. By the end of the series, he is fully reintegrated into Invectid society as a proponent of coexistence, having proven that even an enemy can find redemption.
