Voodoo Remoras
Naturally, these devices are neither the product of any sort of syncretic spirit-based religion, nor made up of actual scavenger fish. A Voodoo Remora isn’t even organic: it’s all raw galvanic fluid and platinum and gold aetheric current wiring and the rest of the old-style Mad Science aesthetic. Just, you know, updated with 21st century manufacturing. Fortunately, most Mad Scientists can’t make the conceptual leap that lets them realize that, just because their science is steeped in pre-Einsteinian physics, their engineering and machining doesn’t have to be late Victorian-era as well.
