The Doctor
Cave Story+Cave Story DSI “ HA HA HA! Finally, it's complete. Mimiga become enraged when we introduce the red flower as a form or medication. Its cause is rather simple. The red flower brings out latent abilities. Not onl this, but it also contains a compound that destroys one's reasoning. And now I have successfully extracted and intensified it. Which is this... ...The Red Crystal. And this Red Crystal-- it works on humans as well. Ha ha! Amazing! Do you understand how extraordinary this is? You don't understand, do you? Well then! I will give you a very special lecture now!!! „ ~ The Doctor to Quote right before his boss fight

Background

This dropdown contains the synopsis of The Doctor's story. Read at your own risk as you may be spoiled otherwise!

Before the events of Cave Story, Fuyuhiko Date served as a medical doctor, accompanying Professor Booster, Itoh, and the Sakamotos on their research expedition to the island. His true intention, however, was to find the Demon Crown and ultimately gain its powers. He eventually succeeded and proceeded to carry out his plan to attack the surface by kidnapping Mimigas to cultivate red flowers and use them as weapons. Momorin Sakamoto tried to stop him, but he tossed her off the island with little effort; how she survived was left unstated. The remaining researchers fled and were scattered about the island. Despite the efforts of Quote and Curly Brace, The Doctor succeeded in finding red flowers and enslaving nearly all of the Mimigas. In addition, he also found a way to concentrate the power of the Red Flowers into a floating Red Crystal, which affects humans too. The Doctor is confronted by Quote within a tower on the Balcony, where he uses himself as a test subject for his new crystal to increase his power. Partway through the battle, The Doctor is unable to control the crystal's power, resulting in the mutation of his body into a hulking, ogreish monster - the Muscle Doctor. Ultimately, the Doctor is defeated, and his body dissolves into a misty cloud of blood. However, the crystal's power allowed him to survive after the destruction of his body. In the top chamber of the tower where Misery has taken Sue, hostage, the Doctor reveals himself to be very much alive, despite the destruction of his human form, and floats into the room as a sentient cloud of blood mist. Misery, wishing to be free of the Doctor's plans, attempts to destroy him, but her magic attacks do not affect the Doctor's gaseous avatar. He decides to punish Misery for dissent, enveloping her in his cloud and causing her to mutate, before possessing the Core. Sue attempts to flee but is caught by the Doctor's crystal and mutated. Ultimately, Quote destroys the Undead Core, freeing Sue and Misery and destroying the Doctor for good.
