 If you liked JoJo no Kimyou na Bouken Part 3: Stardust Crusaders |  ...then you might like Pocket Monsters Special |
This recomendation is strange, I know, but both JoJo's and pokemon share some similarities. Both are long running shounen manga, that can be separated in parts. Each part happens to be an adventure, in another place with another main character, but the universe is the same and previous main characters are always showing up again. Also, fights are somewhat "indirectly", with pokemon and Stands. Universe in both series are in constant expansion and they haven't finished yet.
