Type-α, codenamed "Emperor," (エンペラー) was the second of the Four Heavenly Kings, in this case being a God-like creature made by Goldman created to rule over nature and humanity with an iron fist and protect nature from humanity. Goldman believed him to be capable of destroying any resistance against him. His weak spot is the pink heart-like orb in his chest. After James and Gary successfully brought him down, Goldman threw himself from the roof of his headquarters.
The Emperor is a formidable enemy, wielding the powers of levitation, telekinesis, and shape-shifting. He has four metallic orbs orbiting him, which he can use to attack. His first method of attack is to send the orbs flying one-by-one into the agents at high speed, which must be shot down. After this, he can send the orbs all out at once to confuse the player, and can also use his shape-shifting powers to transform his right arm into a sword/lance-like blade to slowly move forward and cleanly slash the agents. His penultimate attack consists of using his shape-shifting powers to briefly transform his orbs into duplicates of the first four bosses, Judgment (Zeal only), the Hierophant, the Tower (blue snake only), and Strength to attack the players -- hitting these clones in their respective weakspots will cancel the attacks (at the same time injuring him). His final attack involves his drastically increasing its orbs' orbit speed, turning himself invisible (except with his red orb remaining visible) and slowly floating into the agents with the intent of smashing them down with the rapidly-spinning orbs. By shooting the pink orb enough times, the Emperor explodes, concluding the battle.
The Emperor makes an appearance as the final boss in The Pinball of the Dead. During battle, the Emperor will use a combination of four moves, three of which are based on the moves he uses in The House of the Dead 2. He ducked the Magician and died.
The first move that the Emperor uses is that he sends two orbs at the player in order to block the player's pinball. Although he performs this move at close-range, it is easy to avoid. The next move that the Emperor uses is that he will send many orbs at the player. The amount of orbs that the Emperor sends out will fill the screen, but there is a space between each of them. The third move that the Emperor will use transforms his arms into swords, followed by the Emperor slashing in a cross pattern. This move will knock the player's pinball back at the player. The final move that the Emperor uses causes him to transform one of his arms into a giant shield, which protects him from gaining any damage.
- In House Of The Dead 3, The remix of the theme music of the fight with the Emperor is used in fighting the Wheel of Fate.
- In the Sega/Namco light gun game, Vampire Night, the vampire Diane uses the same orb attack as Emperor's.
