Plot: Goten, Trunks, and Lazuli (AKA: Android 18) follow Mr. Satan to Mei Queen Castle (similar to the Monsoon Place in the 007 film Octopussy). There, they find a bunch of Bio-Warriors and scientists in a laboratory. However, Goten and Trunks also find a clone of Broly called Bio-Broly, and when the monster is released, they soon find out that he's just as strong as the original. With Goten and Trunks having a score to settle against Broly and the Culture Fluid absorbing everything and everyone in sight, will the two boys, along with Lazuli, Krillin, and Mr. Satan, make it out of this battle of life or death alive?
With this being the third of four Broly films I'm watching to celebrate Dragon Ball Super: Broly's release, and the most hated of the original animated films, I was expecting my reaction to be like the rest of the Bio-Broly haters when I started this movie, specifically "This movie is terrible, what was Toei even THINKING?!" But by the end of this movie, I found out that it did NOT disappoint!
First off, I'll begin with the upsides, starting with the plot. It was really interesting to see flashbacks to Dragon Ball Z: Broly - Second Coming (specifically the flashback with Goten, Trunks, Videl, and Maloja, and the one where Goku and his sons kill Broly), and to see what happened to Maloja shortly after that.
Then, there's the characters themselves. Goten and Trunks (the kid Trunks, not Future Trunks) return for their second movie appearance, Krillin appears for his 11th movie appearance straight, while Broly and Maloja, the priest from the previous film, return for their last. We also get to see three good guys in the show make their first movie appearances: specifically Hercule, Android 18, and Marron. Hercule makes another appearance in Fusion Reborn, but Lazuli and Marron aren't seen again until Battle of Gods.
Next up is Bio-Broly himself. Sure, his design for the majority of the film maybe a little too weird to put on paper and on screen (more on that later), but he can kick some Super Saiyan avocados. He's just as strong as the original Broly was in Second Coming, but combine the OG Broly's strength with bio-technology, and you've got a force to be reckoned with.
Finally, the battles, and I personally think that they are the highlight of the film. Sure, they're mostly against the main villain, but they didn't disappoint me. Heck, Bio-Broly even put a small dislocation on Goten's shoulder with his Mouth Energy Wave attack, and the animation in the fights is GODLIKE! And they called this movie terrible.
Now for the downsides, which there aren't many. First is Bio-Broly's design. The good thing about this is that it put FEAR in my heart when I first saw it in the 2005 trailer. He looked like something out of a horror movie! The DOWNSIDE however, wasn't how scary he looked: it was how the design looked. It's simple:
Step 1: Take Broly.
Step 2: Melt his skin off so you can see his chest organs.
Step 3: Make his eyes red.
Step 4: Cover him in melted dark green colored Play-Doh so much that you can only see the back of the spikes on his hair.
Step 5: Put lots of blue raspberry Jolly Ranchers in Broly's mouth.
Step 6: You have Bio-Broly.
Now, I'm not saying that this design was bad, heck, I think it was one of the most creative and unique Dragon Ball Z movie villain designs I've ever seen! However, I just don't think it was the right design. I'd rather like it if they did the blue bio-warrior design for this movie, but kept the hair and Broly's eyes the way they were.
The other downside is that Goku barely appeared in the movie. The only parts he appeared in were when the flashback of Broly dying happened, and at the very end of the movie on Grand Kai's Planet. I would like it if the movie was a little longer so we could see Goku and Pikkon fighting Broly in Hell.
In conclusion, other than these two minor downsides, Dragon Ball Z: Bio-Broly is not only one of the most underrated Dragon Ball films (along with Tree of Might, Lord Slug, and Super Android 13), but one of the best Dragon Ball movies YET. Bio-Broly is the first horror movie based Dragon Ball Z movie I have ever watched, and it featured a really unique villain that is sadly hated among most of the Dragon Ball franchises biggest fans.
