"Thunderblast knows the weakest part of any Autobot is his obnoxious sense of nobility. They're constantly rushing to the rescue, and every last one of them would sooner scrap a basket of Antilianbumble puppies than blast a female as pretty as she is. She uses that fact to her full advantage; more than one Autobot has fallen first to her charms, & then to her plasma torpedoes. As an agent of Earth working for Starscream, she knows better than to trust any Decepticon, but she finds a kindred spirit in the con-man Sideways."
~ Description of the toy.

Thunderblast is a Decepticon appearing in Transformers: Cybertron. She is a very flirtatious female. She will automatically try to attach herself to anyone with power including Megatron and Starscream. Despite this, she is very independent and will reject any other Transformer's affections.

Her alternate mode is a boat with flight capabilities.


Transformers: Cybertron

Prior to the events of Transformers: Cybertron, Thunderblast was among the few Transformers who boarded the colony ship Atlantis. While the Autobots watched over and guided human evolution, the Decepticons terrorized humans, inspiring myths and legends alike. Thunderblast became the inspiration for the mythological mermaid sorceress Lorelei.

She, along with many other Ancient Decepticons, regarded as "monsters" are soon rounded up by the Autobot "monster hunter" Crosswise and imprisoned in stasis pods in the North Pole. They were soon rediscovered by Starscream who unleashes most of them to their freedom.

Thunderblast was among the few freed Decepticons on this stasis pods. She was first seen in the South Pacific by scanning a patrol boat for an alt mode. Upon gaining an alt mode, she surfed by and teases the driver of the patrol boat she scanned and left.

As she is enjoying the surf and the sun, Thunderblast soon encounters Jetfire, who unintentionally blocked her view of the sun and mocked her. They two engaged in a short fight before Thunderblast teleported back to Starscream's headquarters on a volcanic island.

Starscream then gathers his new minions as he absorbs Primus' power on the Omega Lock. His new minion cheers for him. Thunderblast, however, got bored and went out to have some fun. She spots a navy ship and began teasing it by running through it via teleporting, thus scaring its crew who believed the mermaid sorceress Lorelei has returned.

She later joined her fellow Ancient Decepticon Lugnutz in defending the volcanic island by welcoming the arrival of Optimus Prime, Override and Evac. The two attack the Autobot leaders, but Optimus was able to sneak out thanks to Override and Evac forming a distraction to the two Decepticons. She is later seen fighting Autobot reinforcements, particularly with Jetfire in a sea-to-air assault, hitting Thundercraker instead.


A closer view of Thunderblast.

  • Thunderblast became a least popular female Decepticon while being popular in fanfiction, with Slipstream and Airachnid being more popular.
  • Not counting Esmeral and Lyzack in the Zone manga as well as Nightbird (who is in fact a stolen drone), Mega (the female Pretender component of Overlord) and Strika, Thunderblast is the first female Decepticon to appear in a Transformers cartoon (although Blackarachnia is the first Transformers villainess even though she is a Predacon), with Blackarachnia's Animated counterpart the second, Slipstream (although a minor Decepticon) as the third, Alice as the fourth, Airachnid as the fifth, Filch as the sixth and Zizza as the seventh.
  • In one scene in Transformers: Cybertron, Thunderblast is shown to have "nipples", as shown in the picture on the right. She is also the second Transformer with "breasts", the first being Blackarachnia from Beast Wars.
  • Thunderblast is voiced by Natsuko Kuwatani in the Japanese version, who also voiced Ryoko Asakura from Melancholy of Haruhi Suzumiya and by Maryke Hendrikse in the English version, who also voiced Gilda from My Little Pony: Friendship is Magic.
  • She vaguely resembles Nightbird, a minor villainess in the original G1 Transformers.
