The survivor of a human hunt finds refuge with the Quests and warns them against visiting Dr. Ashida's Island, but the Quests continue on. Welcoming them graciously, eminent Dr. Ashida soon shares the results of his improved gene therapy on native lizards headed for extinction. They're now as large as crocodiles, ill-tempered, and controlled only by a huge, one-eyed servant named Sumi. Repulsed before a staged dragon duel-to-the-death, Benton leads his group away. Dr. Ashida guides the subsequent discussion to a point where he can challenge Race to a judo match. Though employing unsportsmanlike conduct to win, Ashida loses. He then forces Race to accept a challenge against sumo wrestler Sumi, which Race, with difficulty, also wins. Now, in final retaliation, Ashida waits for the Quest party to leave his castle so he can sic his dragons on them. Written by statmanjeff

One of the coolest Jonny Quest episodes
21 December 2008 | by (Tennessee) – See all my reviews

The Quests pay a visit to Dr. Ashida, an old friend of Dr. Benton Quest's. Dr. Ashida has been doing research with the Tobura lizard. As a result of his research, he has been able to grow the lizards into 14' man-eating dragons. And if Dr. Ashida and his dragons weren't enough, the Quest Team will have to deal with a mountain of a man known as Sumi.

Thinking back to my childhood, there are three episodes of Jonny Quest that really standout. The Robot Spy, The House of Seven Gargoyles, and this one, The Dragons of Ashida, are a big part of the reason that Jonny Quest has such a special place in my memories. It's just so cool! The Dragons of Ashida has a lot going for it. Dr. Ashida is a madman of the first order. He's quite capable of doing anything (which results in his ultimate downfall). And the way he's drawn – he even looks evil. The dragons themselves scared me at one time. Today I look at them and marvel at their detail, especially in the final chase scene. Last, there's Sumi. Just he sight of an overpowering, one-eyed, bald Sumo wrestler was (and still is) amazing. With danger around every corner, two of the most vicious baddies the Quests ever faced, and the threat of ending up dragon food makes The Dragons of Ashida a winner.
