Waspinator is a Predacon who works for Megatron. He is one of the six original Predacons who stole the Golden Disk. His beast form is a wasp.
He is a supporting antagonist in Beast Wars: Transformers and the secondary antagonist in its sequel, Beast Machines.
Waspinator was ordered to assault on Predacon hangar, kill everyone in there, and secure an escape spacecraft while the rest of Predacons under Megatron's command was stealing Golden Disk from By-4, a secret Maximal facility. He was partnered with Buzzbomb, a Predacon loyal to Cryotek. After successfully accomplishing this task, Waspinator is reunited with Terrorsaur who proceeds to kill Buzzbomb. After eliminating Buzzbomb, Terrorsaur and Waspinator debates on what their escape craft's name should be: Darksyde or Buzzerbot. Eventually Terrorsaur's suggestion was won.
Waspinator often gets beat up or blown to bits. Waspinator did not become a Transmetal, as he was knocked into a repair chamber because of the quantum surge. Near the end of Season 3, Waspinator quit the Beast Wars, as he was tired of being evil and getting beat up. His final injuries were suffered when Quickstrike and Inferno blasted him.
After the Beast Wars ended and the Maximals captured Megatron, Waspinator finally found happiness on Earth, being worshipped by the protohumans as a god and claims that he is happy at last.
In the sequel, Waspinator rejoined Megatron on Cybertron after the protohumans kicked him out of their settlement for flicking rocks at their heads and grew tired of his rule over them. Once home on Cybertron, he was transformed into the Vehicon general Thrust.
He loved being a cool biker-bot as he now got respect and was finding chicks dig the new brooding bad boy slick and he also enjoyed being Megatron's new right-hand bot.
Thrust was one of the first of Megatron's Vehicon generals to be created, and was the last one to stand against the Maximals. He is commander of the Motorcycle Drones, he is a dark, cold, brooding type, and is absolutely devoted to Megatron's goals, even though he knows what it means in the end for him.
In the final battle, Cheetor removes Waspinator's spark from the body shell by extracting it.
After Optimus Primal makes the ultimate sacrifice in order to save the Maximals and defeat Megatron by reformatting Cybertron into a techno-organic planet, Waspinator returned to his original Beast Mode body, but retains the head of Thrust and wanted glory and power, but Rattrap swats him away as Waspinator complains that he will never get what he wants.
In the Legacy of Chris Thorndyke, he was once an Autobot known as Wasp before being kicked out for his heinous actions and being stranded for so long even creating those buzzing sounds and he was found by Shockwave which gave him an offer to serve the Decepticons and help in the war of Cybertron or be stranded to die naturally he picked serve the Decepticons and was experimented on making him similar to Blackarachnia but he transforms to a Green wasp and became known as Waspinator and he is the comic relief and always getting himself blown to scrap all the time and later he left the Predacons and the Decepticons after his long rant of being sick of it and the as mentioned blown to scrap and letting them and telling them to lay a huge wet one on his big fat stripy butt before getting blown up and is a head and at least he can still talk but later joins the Autobots and Maximals and still buried the hatchet with Bumblebee and even got to relax in a pool of Energon and even to star in a movie once, which he actually was happy that he got the recognition he deserved similar in the series finale of Beast Wars when Megatron has been ultimately defeated by the Maximals.
He is reprised by Scott McNeil in the English dub and reprised by Kenso Kato in the Japanese
