Thats quite a hard question... though it is undoubtably one of the final bosses. Either Magician, Emporer, Wheel of fate, The world or The magician from house of the dead 4 speical. I don't know about Magician hotd 1 against Magician from hotd 2 but the magician isn't the final boss on hotd 2 so im guessing the Magician will be harder on hotd 1 than hotd 2.
The hardest boss in the House of the Dead series is typically considered to be the final boss of House of the Dead 4, known as The World. This boss battle is known for its challenging mechanics and difficulty in defeating.
Ozma is the hardest boss in the game
The hardest boss in a video game is usually the last one, but it is more of an opinion. Definately fact not opinion the worlds hardest boss in a game is game: mushihimesama Futari, boss: stage 5 ultra boss the fight can also be viewed on youtube.
It matters what game you are playing. For example i play Wizard101 and so far the hardest boss to me is Jabberwock.
If you mean the original game, then it is The Hermit. If you mean the series in general, it could also be Death, Justice, The Tower, and Temperance.
