Most of the Iacon relics are pretty mystical in origin (Apex Armour, Star Saber, Energon Harvester), but there are some that seem to have come right out of G1 Wheeljack’s workshop... The Polarity Gauntlet, a device that manipulates magnetism. I can see Wheeljack practically screwing himself multiple times with this device. (Polarity gauntlet - Transformers Wiki) The Immobilizer, a device that stops Transformers in their tracks. This was a clear homage to inventor Wheeljack, as well as the similar device he made in G1. (Immobilizer - Transformers Wiki) The Force Field Generator. I’m a bit surprised this isn’t commonplace within PRIME, after all haven’t many Transformers/their ships used force fields for defence capabilities? (Force field generator - Transformers Wiki) The Phase Shifter, a device that generates intangibility for its user. (Phase shifter - Transformers Wiki) ... And so on. It’s not really a complaint, as they are of value and use. But gadgets, inventions and tools shouldn’t really be placed in the same category as the mystical relics or the MacGuffins for the show (rainbow-colored Energon). They deserve to be invented, by an Autobot/Decepticon scientist to assist either side in their battle (like the cortical patch). I’ve said before that the lack of inventors currently in TRANSFORMERS is a little disappointing, as the writers don’t seem to be imaginative or creative enough to have inventors who can design fantastic devices but instead have them already designed by long-gone Cybertronian artisans (eg Solus Prime) and turned into MacGuffins to pop up when necessary.
