"Wide-area tactical robot proficient in electronic warfare. Can short-circuit or take over enemy robots through electrical discharge or lightning strikes through remote-control lightning rods."
- Stage Select Description

Mighty No. 3, Dynatron, is the third robot in Dr. White's mighty robot line.

She is one of the two female Mighty Numbers, along with Cryosphere, and she is the boss of the Power Plant stage.


Dynatron's torso is based off of a purple light bulb. She wears a yellow/black, zigzag, lampshade-like cape that can sometimes be seen through. She has dark skin, red eyes, purple hair, and pointed teeth. Her legs are yellow points that typically are paired together. She has two antennae that resemble white coil wire with yellow interiors. Though her official art shows her hands behind her back, concept art shows that she has clawed hands. She is 191cm/6ft 3 inches tall, and weighs 91kg/201lbs.


Dynatron goes berserk along with the other first eight Mighty Numbers. She invades the Power Plant for electrical energy.

If she is defeated before Beck heads to the Capitol Building, she will appear in the stage to disable some electrical wires.

She appears in the Robot Factory stage along with all of the other Mighty Numbers to assist Beck.


Dynatron is a hot-tempered, impatient robot who becomes particularly irate if she is stopped from feeding on the electricity she craves. However, she doesn't seem to relish combat, as indicated by her troubled remarks when she sees Battalion's enthusiasm during the attack on the Robot Factory. She voices all of her sibilants (pronouncing s sounds like z sounds) and draws them out to make them sound like crackling electricity.


Dynatron has control over electricity. She can send out little purple circles with yellow spikes to redirect her electrical sparks and lighting.

Boss fightEdit

The boss fight is actually quite simple, with very few attacks, but they can be very dangerous.

Attack 1: Dynatron fires multiple bits that can stick to walls and to the player in 2 different ways: firstly, she may fire them all in the vicinity of the player, attempting to stick them all to him, or she may fire them in a wide spread towards the player, trying to make an area of extreme danger for her next attack. When shot, these bits can be destroyed and count as projectiles, showing the use for reXelection: Brandish, to destroy these extremely quickly and easily with all of the techniques available. If the bits stick to the player, they can be destroyed by mashing the controls, much like breaking out of ice in Cryosphere's boss fight. Some can stick to he ceiling and walls, rendering them impossible to destroy.

Attack 2: After firing multiple volleys of bits, she will go into the top corner of the screen, and fire a continuous stream of electricity to all the bits, including the ones on the player. after a few seconds of firing, she will go down to the bottom corner of where she was before, changing the paths of the electricity as she does so. After a few more second of firing, she will stop, destroying all the bits.

Attack 3: Despite its simplicity, this attack is actually quite hard to dodge as it is not telegraphed in any way. She will attempt to harm the player through contact damage and reposition herself, while putting herself at risk from your shots. She will do this in a few patterns, including just plain moving along the bottom of the stage, which can be avoided by boosting over her, or, she may move up suddenly while on her path, before sinking back down and continuing, which can be avoided by boosting under her while she does this.

When down at half health, she improves her first attack with glowing bits, that, when electrified, release sparks that travel along the walls and ground towards the player.

In Mighty Gunvolt Burst, she has a new attack where she creates spinning electrified sticks to the player. And she can create shields that slide around the floor. When her health is low, she performs an attack similar to Gibril from Azure Striker Gunvolt 2.


Both Dynatron and Mighty No. 8 were meant to be female. While No. 8 changed, Dynatron's gender was kept. The development team started by mixing up possible attacks, placing lighting rods around the arena and on the character. They decided to take an easy to understand motif (electricity) and add new ideas to it. She was then given her purple design and personality. The Development team combined the Japanese god of thunder, Raijin, with everyday appliances, like power cables, outlets and lamps. Inafune asked the team to make her scarier, hide her hands more and to slim her legs down, so she looks like she's floating. Kimo Kimo reworked the design and gave her the yellow/black cloak. At first she made her hands little drums and electrodes, before Inafune choose to give her actual hands. The hands where made into claws attached to coils. The cloak was reworked to let her open it, creating the final design.


  • While Dynatron is a female, she also has the properties of electricity. This could be used to determine if she is a tribute to Elec Man from Mega Man. She is based off a purple light bulb, which proves she is also based off of Bright Man from Mega Man 4.
    • She might also possibly be based off of Plasma Man, an early concept design for a Robot Master in Mega Man 9 that eventually became Plug Man.
    • Her name might have been derived from the name of Dynamo Man, another electrokinetic robot from Mega Man and Bass.
  • The antennae on her head and disks around her are possibly a callback to ThunderMan.EXE. The disks could also be based on the orbs of Cloud Man.
  • Her working design has a slight similarity to Layer from Mega Man X8.
  • In Mighty Gunvolt Burst, in an attemp of trying emulate the NES palette limitations, her eyes displayed as purple instead of red. However, this is also present in her official artwork.
  • Not sure why no one else notices that she has a Raijin, Japanese thunder god, inspiration.
