10 ugly bionicles go
These are in no particular order.
To begin, we have the promotional sets. Bad Guy is just that- bad. His clashing colors, maskless piraka head, poorly-designed legs- there’s nothing to like other than his meme potential.
Speaking of memes, here’s Good Guy. An improvement from Bad Guy albeit not by much. His colors don’t clash nearly as much as his evil counterpart, and he has more than one point of articulation in his legs. In the case of promotional sets, good triumphs.
Of course, there isn’t only one Bad Guy. Introducing QUICK Bad Guy, perhaps the ugliest set I’ve ever seen. I understand these are promotional sets, but this… thing… is proof little effort was put into their design.
Just no…
Perhaps this is cheating, for this is a combiner build. Nevertheless, this was released as an individual set, so I believe it should count. Ultimate Dume, from your inconsistent design to your wonky proportions and chompers which give Mileena something to gnash her teeth at, you miss nearly every mark. At least you provide a plethora of good parts and a fantastic mask.
Umbra is, in my opinion, one of the less offensive sets on this list. While his color scheme is all over the place, and his general construction is nothing to write home about, this set does possess some interesting aspects- that being his dualblade with the built-in rhotuka spinner and his wheeled feet.
Tarduk, plain and silly-looking.
Does this set need an explanation?
They really missed the mark with scorpions in G2.
Perhaps my most controversial choice. Mata Nui is a set I both love and hate. I love the torso design and how it implements pistons in a manner similar to that of the Great Spirit Robot and the toa mata; however, everything else about the set rubs me the wrong way. His arms are rather spindly given how bulky his torso and legs are. In addition, this set is dreadfully gappy. My greatest gripe is his color scheme; keetorange, yellow, pearl gold, and pearl light grey do not mix well. Nevertheless, despite this set’s faults, it’s a far-better sendoff to Bionicle G1 than Stars.
Remember that time Takanuva took a shadow leech meant for you? Ever wonder what would've happened if they'd turned you into a Shadow Toa? -a Villager
Actually, I honestly wasn’t aware that it happened. Given the end result, though, I’ll have to thank him if I ever run into him again.
If I’d become a Shadow Toa, I likely would’ve spent that battle being kicked around by a pure-Light Takanuva, before I got Klakk’d and left with even more issues. On the plus side, I’d be a Toa, so that bullshit with becoming Teridax’s Turaga would be off the table.
