this guy has skin-like coverings for his gills and a variety of wet suits (most of them are just regular wetsuits in different camouflage tones for different depths/bodies of water but he has one with tubing throughout that connects to a tank of water on his back so he can keep himself wet and able to access his enhancements on land) and i've just been assuming that he found someone cool to design them for him... i'd love if that someone was icarus!
