>>9684818>Which line has a huge ton of characters and has a lore to support the line?I don't think what you doing is healthy because collecting for the sake of collecting is retarded.
But if you really want a deep hole just go down the path that is the Kamen Rider SHF line.
Not only do they have a trillion of them from each show, they also have a shitton of side bikes/vehicles/monsters that will keep you busy unless you are really fucking rich and resourceful.
