Cyborg Beast

This is what happens if you overdose on something, kiddo.

The Cyborg Beasts (サイボーグビースト Saibōgu Bīsuto) are freakish fusions of animal and machine, born from exposing Transformers to dangerously high levels of Unicron's Angolmois Energy.

The Cyborg Beasts include:

• Dirgegun, cyborg bee.
• Hellscream, cyborg shark.
• Max-B, cyborg dog.
• Thrustor, cyborg velociraptor.
• Untite, cyborg hyena.

They are sometimes also known as "Cyber Beasts"; in which cases, they are overseen by Gigastorm as their leader.

When coming into contact with Angolmois Energy, Megastorm was transformed into the more powerful Gigastorm. He set out, creating a new subfaction within the Destrons, the Cyber Beasts. To fill up this subfaction, Gigastorm exposed BB, Dirge, Starscream, and Thrust to Angolmois Energy, transforming them into Max-B, Dirgegun, Hellscream, and Thrustor. Beast Wars Sourcebook

As Magmatron surveyed the apocalyptic future Shokaract was destined to usher in, he saw Dirgegun engaged in furious combat with several other Predacons. The Ascending #1

Maximals and Predacons alike rose up to confront Shokaract, but he unleashed his own warriors: Hellscream, Max-B and Thrustor, along with Antagony and Hardhead. The Ascending #3 These heralds battled the Cybertronians being led by Lio Convoy and Big Convoy, but it was ultimately a treacherous underhanded sneak attack by Ravage (combined with a grenade or two) which ended the threat of the Cyborg Beasts and their allies. The Ascending #4

Notes

• The Cyborg Beasts are never referred to as such in either their original toys' packaging or the cartoon. The name was primarily used in the Beast Wars II manga and other print media, originating from material published ahead of the toys' releases.
• A longstanding fan belief is that Gigastorm is also a Cyborg Beast. Though he did play a pivotal role in upgrading the Combatrons into the Cyborg Beasts in both the cartoon and manga, Gigastorm himself was not a Cyborg Beast in any of the original Japanese fiction. Likewise, in IDW Publishing's Beast Wars Sourcebook, Gigastorm is not labeled as a "Cyber Beast", either, but is stated to be their leader.
