Grasshop

Lava P. Grasshop - A former member of the Big Four (he was "fired" due to failure in the episode "Dark World", he is a grasshopper-type Invectid who normaly uses technology to defeat his enemies. He has (unfortunately for him) seen little success against the Spider Riders, and is often seen with disdain and disappointment by the other members of the Invectids.

He was banished from Invectid state and forced to wander the Inner World, swearing to defeat the Spider Riders. Due to recently assisting the Spider Riders (Sparkle in particular) escape captivity, and for that he was known as a traitor to the Invectids. Sparkle calls him Uncle Hop. One of his biggest achievements in helping the Spider Riders is removing the Battle Beetle's regeneration device, allowing Hunter to defeat it in Numma.

According to his wife, Weeval, his promotion to the Big Four was a mistake as he is a gentle bug and loves children. This might explain why he gets along so well with Princess Sparkle and allows her to call him "Uncle Hop". It may also explain why he is reluctant to actually fight in general. In "Welcome Back" he tries to reason with Lord Mantid by saying that after having spent time with the humans he realized that they aren't mean and greedy like he'd always said. He tells him he can do whatever he wants to him, but to spare the Riders. Mantid was going to kill him by smashing him into the ground repeatedly, until Buguese stepped in and told Mantid to fulfill the promise he made. Mantid dropped Grasshop and Princess Sparkle rushed over to him, thankfully he was unhurt. He cares dearly for his wife, Weeval and his children. After he takes the Spider Riders through the sewers, he is finally reunited with his wife and kids.
