Exkaiser is the leader of his Space Police Kaisers team, he can combine with his auxiliary trailer unit King Roader to form King Exkaiser, with his jet/robot drone Dragon Jet to form Dragon Kizer, or with both vehicles at once to form Great Exkaiser.

Exkaiser has a strong sense of justice as well as always following his moral code, refusing to take a life even if it belongs to that of a villain. Being the leader of a Space Police Kaisers squad, he also has excellent commandeering skills. On his own, Exkaiser is an agile, powerful and skilled fighter, capable of tackling numerous enemies which are superior in size compared to him. During battle, Exkaiser exchanges his normal blue chestplate for a lion's face with a flipping action called "Breast Change" , which switches back after the battle has finished (though this is rarely seen, as Exkaiser usually transforms with the lion face already deployed). He can project the Forming Beam from his headpiece or utilize a device on his finger that can fix broken machinery (like Kouta's broken camera in Episode 1), and yellow beams from his eyes that can power up machines. He also has built-in hovering abilities. He forms the interior of King Exkaiser, Dragon Kaiser and Great Exkaiser.

Exkaiser's alternate mode is a sports car, specifically the Hoshikawa family's car. When changing into Robot mode, his everyday vehicle mode shifts into a more exotic form capable of transformation.
