Ujimasa Hōjō

Ujimasa Hojo is Ujiyasu's second son, Ujinao's father, and the fourth leader of the Hojo clan. He is famous for resisting Hideyoshi Toyotomi's rule until his end.

Samurai Warriors
In Samurai Warriors 2, Ujimasa appears as a generic general in a few battles. He appears in the Toyotomi's Siege of Odawara Castle on both West and East sides. On the West side, when the player makes it to the top of Odawara Castle, he will warp to the other side of the battlefield and charges to the Toyotomi's main camp. On the East side, he will still stay in the top together with Ujinao. In both scenarios, he relies heavily on Kotarō's trickery to defend their home. He also appears in Nagamasa's fictional Dream Stage, where he and a few other Hojo generals battle alongside Shingen and Kenshin.

In Kotarō's story mode, the Hojo rule the majority of the main land thanks to their vassal's unstoppable army. Ujimasa is pleased with being the land's new ruler but Kotarō, to amuse himself, decides to kill his master. Trapped in the highest level of the castle, Ujimasa attempts to flee and rally his forces. If he is quickly assassinated, Ieyasu and his men will appear on cue to attack the stranded Hojo generals. Should Ujimasa escape, Kotarō's army will see that their ploy has failed and their morale will weaken.

He was rumoured to appear in Samurai Warriors 3, however his father made it to the cast. He may still appear in future installments.

Warriors Orochi
In the series' canon, the Hojo first appear fighting against the Orochi army right after they are warped to the new world. The Hojo army gets defeated here and some generals manage to escape, including Ujimasa. After this, they are aided by the Shu army when they are struggling against the Orochi army.

Kessen
In Kessen III, he joins the Ashikaga shogunate during the later part of the game. His reasons for joining the anti-Nobunaga resistance are not clear, but it's likely due to his general distaste for the daimyo.
