Blaster Master Wiki

Fred was Jason's pet frog from the first Blaster Master. At first an ordinary frog, Fred grew to enormous proportions upon coming into contact with radioactive chest and then led Jason on a chase throughout the underworld. Jason was forced to kill his pet frog not once, but twice, during his journey. Despite Fred's "deaths," he escapes the underworld unscathed along with Jason.

Even though Fred is one of the catalysts for the events of the series, he would not be seen or mentioned in any subsequent adventure until receiving a heavy revamp in the Blaster Master Zero series.

Fred serves as the boss of Area 4.

In Battle[]

BM Boss4
Battle with Fred


Area 4



Pause Trick



Fred has a few different attacks, and he follows a pattern:

  1. Three hops
  2. Lashes out his tongue
  3. Two hops
  4. Spits out three pairs of small fireballs
  5. Three hops
  6. Spits out one large fireball, in the direction of Jason
  7. Repeats cycle

He's only vulnerable when his mouth is open. Grenades are the most effective against Fred, if the player doesn't have a powerful Gun.


Classic Series[]

Worlds of Power: Blaster Master[]

Although Jason does encounter a hologram-frog at the end of Area 4, it's simply the image of another bullfrog, not actually Fred (whom he would encounter later).

Blaster Master: Enemy Below[]

A functionally identical frog boss simply named Poisonous Frog guards the Hover Pack at the end of Area 3.

Blaster Master Zero Series[]

Blaster Master Zero[]

It turns out that Fred is actually an autonomously operating drone that SOPHIA came equipped with. According to Eve, when the drone arrives on a planet, it disguises itself as a creature native to that planet and begins working. The purpose of the drone is to gather intel and learn the whereabouts of mutants. It can send that intel to SOPHIA, to stopover checkpoints, and even all the way back to Eve's home planet. However, in order to keep SOPHIA's whereabouts concealed, intel can only be transmitted at certain times. Because of that, there are times when SOPHIA isn't able to receive signals. That's why the drone has a function that allows it to make a wormhole that is connected to SOPHIA's location. It proves to be really useful when acquiring intel and sending data.

Fred appears in Blaster Master Zero and is again the catalyst of events. Instead of being a normal frog, however, it's a drone sent by SOPHIA III to investigate mutant infested planets. When it arrives on Earth, it takes the form of a frog-like animal and is discovered by Jason Frudnick. Jason keeps Fred as a pet, but it eventually escapes, and travels through a self-generated wormhole to SOPHIA III. Jason follows it, and discovers SOPHIA III for himself. Jason follows Fred's signal and eventually recovers him. Later, Fred leads Jason to Sophia Zero.

Blaster Master Zero 2[]

Fred carries on as a member of Gaia-SOPHIA's crew, now sporting a silvery skin (the cause of this color change is unknown even to Eve). His ability to generate wormholes is now a Menu function, safely recalling Jason to the tank's position if he gets stuck in side view (though this function has a maximum range and will not work if Jason is in a different room from Gaia-SOPHIA). Fred will also hop out from Jason's person and open a quick-return wormhole out of top-down view dungeons upon picking up the primary upgrade item contained within.

Outside of side-view areas and top-down view dungeons, Fred enables travel between sectors of the Space Map by synchronizing with naturally-occurring dimensional tunnels and opening them for use by Gaia-SOPHIA. However, Access Keys are required in order to allow Fred to open dimensional tunnels other than the tunnel connecting Area A and Area B.
