Dynomutt is the dog sidekick of Blue Falcon and the title character of the Dynomutt, Dog Wonder animated television series. He is a cybernetic canine equipped with special mechanical powers and fought crime in Big City. In spite of his position, however, his frequent screw-ups and malfunctions are a major headache to many of Blue Falcon's cases. His voice was originated by Frank Welker.

Character description

Dynomutt is a friendly, yet goofy grey doberman who is always eager to please his allies, mainly his follower Blue Falcon. Despite doing his best to aid him, Dynomutt mainly comes off as more of a severe hinderence due to him being jokester, making quips and puns out of situations. His malfunctions make him appear quite foolish and cause a lot of frustration for Blue Falcon (or B.F. as he calls him), but he always proves himself as a liable hero by the end of an adventure. He is addressed to by Blue Falcon as either "Dog Wonder" or—when one of his malfunctions makes a bad situation worse—"Dog Blunder".

Dynomutt wears a green superhero outfit, consisting of a cape, mask, gloves, and boots. His chestplate is adorned with a yellow "D" in the middle. In his civilian identity, Dynomutt usually wears a red, long-sleeved jacket and a light blue scarf.


Being a cyborg dog, Dynomutt has several abilities and tools that aid himself and Blue Falcon in their crime-solving adventures. He has superhuman strength and is durable enough to withstand a lot of damage.

His most common ability is extending his limbs and neck, employed by a system of miniaturized transistors, to make himself taller, reach further to certain areas, and perform extraordinary feats. While this ability seems to be handy at first, Dynomutt tends to be tangled by them on occasion. In addition to simply extending his limbs, Dynomutt's legs can also turn into springs that allow him to make fantastical bounds.

Dynomutt has built-in gadgets hidden within his mechanical body, ranging from various tools that aid a given situation, to traps that capture villains, to weapons such as knives or mallets. Despite this, he sometimes uses the wrong gadget when trying to acquire one.
