Waspinator

Early Life
Wasp was a young bot who joined the Elite Guard Academy during the rise of the Decepticons. He was dedicated to joining the Elite Guard. Wasp even idolized Magnum, the Elite Guard squad leader.

During his time in the Elite Guard, Wasp was seen as a great rookie in Sentinel Minor's eyes. Sentinel even helped Wasp become a real soldier. Wasp even met his rival in the academy. This was Bumblebee, another bot with the same protoform template as himself.

When Wasp was near graduation, Bumblebee came with evidence saying Wasp had given information about the Elite Guard to the Decepticons. This caused Magnum, now Magnus, to kick Wasp out of the Elite Guard.

Insecticons
Leaving with hatred towards Bumblebee, Wasp got to the Decepticons. He met other bots there. One of them was Bombshell. Bombshell and Wasp became friends as both of them had hatred towards the Elite Guard who worked alongside the Autobots. The two even joined the Insecticon Project lead by Shockwave.

After this, Wasp was known as Waspinator. He worked alongside the Decepticons for a while. Even having Bombshell as his commander. But when Waspinator met Bumblebee again, he went against orders and fought his rival bot. Bumblebee got help from Cliffjumber and because of this, he was beaten.

Retreat
Retreating, Waspinator ran into the organic Transformer, Blackarachnia. The two teamed up after this to get their revenge on the Autobots. They made a new version of the Insecticon Project called Project Arachnid. This was supposed to create large spiders. A cross between metallic and organic. This was stopped by the Autobot commander, Optimus. This battle ended with Blackarachnia being captured and Waspinator escaping.

Waspinator later believed he could recreate Project Arachnid. But this time, he kidnapped Transformers and remade them. One of these bots were Sandstorm. Sandstorm went crazy out of this which made Waspinator try to change the formula. This was supposed to be better, but it was shut down by the Decepticons. Waspinator was also captured by them. Shockwave had him in stasis lock until after the Ark left Cybertron.
