Dynomutt is a talking cyborg dog who fights crime alongside the Blue Falcon.

Powers and abilities

  • Super strength
  • Extendable limbs: Dynomutt can stretch any body part.
  • Concealed gadgets
    • Fishing equipment
  • Transformation: Dynomutt can transform his body into virtually anything such as a raft.


Early life

Reggie (Heart of Evil)

Reggie the guard dog.

Dynomutt was once Reggie, an ordinary guard dog belonging to Radley Crown. He was rebuilt by Dr. Quest after an near-fatal encounter with a dragon-suited intruder.

Scooby-Doo! Mystery Incorporated

Season two

He helped the gang after Scooby-Doo was kidnapped by mistake instead of him.



  • Despite the reimagined Blue Falcon's gruff exterior, the reimagined Dynomutt is relatively the same, with his former life as a guard dog filling up that role.

Appearances in other media

  • The original version of this character first appeared in Everyone Hyde! (which featured a cross-over with the original gang) of the ABC TV series, Dynomutt, Dog Wonder.
