Kyoushoku Soukou Guyver (2005), JoJo no Kimyou na Bouken (TV) Recommendations
Both are modern anime adaptations of classic manga from the 1980's. They both have a protagonist, who use their superhuman abilities to fight strong evil creatures (vampires in JoJo, zoanoids in Guyver). Both are very action-packed anime with blood and gore. The big difference between the two is that JoJo is horror, while The Guyver is sci-fi. If you like one, you will enjoy the other.
