The loss

When Threetails was 10 years old, the Silent Planet was under attack by Eggman, destroying everything in his path he desided to hunt down Threetails and her family. Threetails, Dexter, River and their father, Arthur Firefly were hiding in a near by cave, trying to protect her family Threetails check to see if Eggman had left the planet, thinking he had she desided to walk out of the cave to only them be caught by Eggman. He then caught Threetails's family and ordered Arthur to hand over the Lightning Crystal (which contains a huge amount of energy which can destroy the whole planet), Arthur then refused which then caused Eggman to order his robots to kill him, Threetails watching this whole moment told Dexter to cover his and River's eyes, after that it was to late for Threetails to cover hers, her father had been killed right infront of her face. Eggman then took Threetails and her friends to his base and raised them to become strong warriors. Threetails still depressed from what she saw gave up everything to become the strongest warrior in Eggman's army.


Threetails does appear in the Sonicpower Comics, in issue 2 she believes that Topaz has been working with the enemy, which results in Topaz killing herself but some how comes back, another thing is that Threetails and Shadow have become a couple during this issue.


She can control electricity, it doesn't hurt since she has armour around her, and also can absorb it. She can also levitate. Also, the electricity is her life force, if it's gone, she dies. She also owns a glove that has claws that is her weapon(used in battle and was used during the battle of the Silent Planet). She can also, by using the Lightning Crystal, can turn into her Super Form, Thunder Threetails. She can also ride her hoverboard, the "Golden Thunder". She also, like Bruce and Dexter, has a Guardian Form, as she is the protector of the Silent Planet, she turns pink while in this form, she can enter this form with the Lightning Crystal. Being a Guardian means she can heal people, and bring them back to life, using her electricity. She can also teleport using the Silent Energy. She can also make Silent Blasts, Electro Blasts and use her Electro Bullet attack.

She can also turn into a werefox(her wereform), but only when she's really, REALLY angry and at nighttime. She is only able to access this form once a month for an unkown reason.

Thunder Threetails is the Super Form of Threetails the Fox. Unlike other super forms, Threetails can use it whenever she is angry, the Crystal glows and she accesses it.

Uses of the Lightning Crystal

She uses it when she is angry. She has used it alot of times, but it was painful, so she hasn't used it again. Whenever she is in her super form or guardian form, she always has a purpose but it's varied(of reasons only she knows).

Forms accessed though the Lightning Crystal:

  • Thunder Threetails (Super form)
  • Guardian Threetails: (Guardian form)

Forms accessed though pure anger:

  • Threetails the Werefox (wereform)


Threetails has some weaknesses, she has a huge fear of water and can't swim, reason why she's afraid of water is because when she was little she nearly drowned in Diamond Reef Zone, luckily she was saved by her father. She is also fairly aggressive at times which can cause her to be very destructive.

Love Interest

Shadow the Hedgehog


She can get really aggressive, she is also a bit nice, only sometimes though(when she's in a good mood). When she is mad, only Crystal and Eevee can calm her down. Like one instance when Shadow and Rouge were making out, she wanted to get them, but Eevee said" No, you are superior, they are inferior"(even though Shadow likes Threetails now). When she's really really mad she'll start going off at her friends it sometimes goes as far as her fighting her own family. She's not as hyper and crazy as she used to be, she's more serious. (some people even say she's starting to become more like her father)

Her depressed theme


  • Threetails's name was originally Crystal.
  • She also was originally a wolf.
  • Threetails never had a design until January 2011.
  • Although she doesn't look it but Threetails is the most powerful person on the Silent Planet. Ed comes second and El Dorado comes third.
  • When ever Threetails is mind controlled her eyes turn red and her fur turns to a dark gold, but no one knows that she is being mind controlled.
