Billy Thunderman is the youngest son in the Thunderman family. He was born with the ability of super seed. He is often bugged by Nora, but they learn to work together, like any good ranger team.

He is portrayed by Diego Velazquez.

Character History

Danger Thunder

Alongside Max, Henry, Ray, and Nora, he became a one off ranger as Danger Green via a special type of bubble gum. He goes off with his siblings to find their Ohman stones shortly after meeting Captain Marisol.

Galaxy Squad

Ironic for a guy known for agility, Billy becomes the Tauren Galaxy Ranger. It is also a coincidence that another of his siblings, Phoebe, is also a Black ranger, albeit a snake motif like Nora. He and his siblings (and the other rangers) often faced her, but Eustus MacAlister's revival helped them gain an edge. However, his sister had devised a plan to free Dark Mayhem and Destructo. The Thunderman's and Henry ultimately faced Dark Mayhem, who took their powers. Now a mortal, Billy decides to go to law school.


However, Dark Mayhem had not completely destroyed their powers, so he joined his siblings and the rest of the Galaxy Squad Rangers in getting them back.

Literary Morphers Edit

Phoebe, Max, Nora, Billy, and Chloe avenged their father's death at the hands of White Rhino Sentries and returned to assist the rangers, riders, and troopers as the T-Force (thus, not counted into the 199 heroes).


Billy stands out from the rest of the Thundermans family in that he is down-to-earth, sweet, polite, friendly, nice and kind to people. Billy is very dim-witted, but he is always cheerful and optimistic. While his siblings are manipulative and competitive, Billy tries to help them and agree to their plans. Phoebe, Max and Nora often take advantage of his sweetness to make him do things for them. Billy has a hard time keeping secrets and ends up exposing them accidentally, most of the time.


Powers and Abilities

  • Superhuman Speed: Billy has shown the ability to move at unreal speeds with ease. Although he is capable of generating a force along with him that he can use for various effects, he has not been able to control it and really doesn’t know about it.
    • Cyclone Spinning: Billy is capable generating cyclones by just superspeeding in circles at extremely fast speeds. This can be used as a vacuum or for a fan-like effect, allowing him to suck up small objects and repel other objects with ease.
  • True Sight: Billy has the power to see and hear ghosts.
  • Heat Resistance: The Bull Stone bonded with him and allows him to function normally under extremes
  • Super Strength: The Bull Stone also increased his strength, one of his father's powers
