Objective breakdown as follows:
- Universe Scale - Bionicle took place on a singular planet broken up into three and within a large, potentially planet-breaking robot, and a small island in the reboot. HF spanned across multiple planets and galaxies.
Advantage: HF. - Powers and Tech - Bionicle G1 alone had Kanohi, Elements, Powers, Powered Weapons, and just about everything under the sun. HF really only had a fraction of that stuff, but they also had the Doom Box, which had the power to erase entire galaxies from the face of existence.
Advantage: HF. - Numbers - There may only be about 40 active Toa remaining (not counting those on the Red Star), but HF and the known villains would somehow also have to pacify every other MU inhabitant as well, and that’s before factoring in the entire planet’s worth of Agori, Skrall, and Glatorian.
Advantage: Bionicle. - Creature Scale - A species of Kaiju-like beasts still pales in comparison to said large, potentially planet-breaking robot previously mentioned above. And Bionicle had two or three of them, depending on what universe you’re currently looking at.
Advantage: Bionicle. - Piece Quality - HF used to hold the advantage here, but Bionicle caught up back in 2015.
Advantage: Draw. - Plot - HF had a lot of unresolved stuff within it’s storyline. At first glance, Bionicle seems to have the advantage here… until you factor in G1’s unfinished story serials, and the lack of characterisation of G2’s villains.
Advantage: Draw.
As far as personal preference goes, HF has potential, but I like the overall theme of Bionicle more. In an actual fight, however, the determining factors are undoubtably the Doom Box, the timing of its usage, and whether or not the characters of Bionicle would be capable of disarming it.
