If you don't already know, this was an early anime film by Akira Toriyama, best known for being the creator of Dr. Slump and Dragon Ball, with this film sharing many elements with the latter. The premise of the story follows these two characters Kosuke and Rikimaru, who are the guardians of Konpei Island whose job it is to protect the last living dragon from harm. Partway through the film's villains (who share a strong resemblance to the Red Ribbon Army) show up to steal the jewel from the dragon which leads to a huge fight scene. The final battle against the main antagonist, Michael Commando(who shares a heavy resemblance to Commander Black) is honestly quite enjoyable with many great action scenes that look like they're straight out of early Dragon Ball.

Overall, I thoroughly enjoyed this. If you're a fan of Dragon Ball, or martial arts anime in general, then I definitely recommend at least giving this one watch-through as you won't be disappointed.
