Inspired by Neptune, the bulky aquatic Stardroid from Mega Man V (Game Boy), this list captures the spirit of underwater exploration. With his half-human, half-fish appearance and command over water-based powers, Neptune would be the perfect overseer of these aquatic observations. From vibrant freshwater species to the mysterious creatures of the deep sea, this collection celebrates the resilience and adaptability of marine life, much like the powerful Stardroid himself.
