I recommend this tokusatsu fanfic written by myself. There are a lot of digging holes in the early stage, the plot has a beginning and an end, it is a bit slow and unsystematic, the world is a fusion of armor 1 to 4, a self-created supplementary world view, a lot of foreshadowing, there will gradually be more original armored warriors, and many original alien civilizations, the plot will definitely surprise you in the future.
