Robot Dog

"Dr. Light: Behold! my greatest invention! Rush, the robotic dog! Mega Man: What? A robotic dog? What's so great about that? Does it transform or something? Dr. Light: A transforming robotic dog? Of course! Absolutely brilliant!"

- Bob and George

Robots are cool. Dogs are cool. Put them them together and you get a Robot Dog!

Unsurprisingly, the best traits a dog could have make for excellent traits in robot companions: loyalty, friendliness, a fierce protective streak... so why not jump to the logical conclusion and combine the two? A Robot Dog has all the good perks of a lovable pooch without (theoretically) any of the bad! Tearing furniture up, hiding your slippers, leaving hidden piles of poop for you to step on in the yard? All a thing of the past should you own one of these metallic mutts!

However, these traits also make them a force to be reckoned with. If you thought a fiercely loyal and aggressive attack dog was scary enough, those traits are so much worse in a more durable, powerful robot than can be armed with all kinds of weapons.

As a rule, Robot Dogs tend to be owned by scientists of both the benevolent and mad varieties, tech geeks, kids with family ties to influential toy and robot companies, as well as evil overlords, CEO's, and any other unscrupulous types with money to burn.

In fact, it becomes a plot point after Ressi is captured and reprogrammed by a Corrupt Corporate Executive, as there is almost nothing manmade at sea capable of swimming at Ressi's top nautical speed, which equals to that of a swordfish (about 50 mph). Ressi is finally re-captured by the only boat capable of reaching that speed underwater.
