Kamen Rider Black

Gen Urobuchi has stated that Black was a huge influence on Gaim - specifically, the duels between Black and Shadow Moon were what influenced the show's writing.

This movie takes place in an alternate universe (where its storyline could be considered a prequel to the events of the TV series). In 1999, an enormous meteor crashed onto Earth carrying extra-terrestrial creatures. In order to counter this new threat, ZECT was formed. Seven years later, in the year 2006, power struggles in ZECT have caused a new group, known as Neo-ZECT. With three groups in existence (Neo-ZECT, ZECT and the Worms), Tendou has decided to sell his power to either Neo-ZECT or ZECT, but his intentions are unclear. ZECT reveal a plan to save humanity, but unknown to other is a plot to destroy man kind.

Both have a darker overall plot but are very episodic with a lot of the episode plots being silly one offs. Lupat is sillier while black has a darker ending

After being kidnapped by the cult Gorgom on the night of their 19th birthday, stepbrothers Kotaro Minami and Nobuhiko Akizuki were submitted to a cyborg surgery with the purpose of becoming the candidates for the next Gorgom Creation King. Both of them are called Century Kings and are destined to best each other in a final battle - whoever wins will become the next Creation King. Kotaro escaped before getting brainwashed (which is the final step in the surgery), with help from his foster father, and turned against Gorgom. He soon finds out the horrific truth from his stepfather: Gorgom originally killed his true parents and, since both Kotaro and Nobuhiko were born on the day of a solar eclipse, referred as "Black Sun" and "Shadow Moon". Kotaro, taking on the name of Kamen Rider Black, was determined to rescue his stepbrother from Gorgom while protecting Japan.
