EXY was one of the three original dolls from DOJ and she was the expert-enhanced Element Doll. Her normal shot and laser were both strong, her speed was medium but she carried the fewest bombs.

As per Cave's DOJ page (in English!), "One of the classic proto-type built few centuries ago, which concentrated on maneuvering and arms rather than the pilot's safety." She was aimed mainly for combat effectiveness thereby not guaranteeing pilot safety. She was highly acclaimed by expert pilots.

In DFK's ending, it was revealed that EXY went into the computer system. Upon emerging, she felt the need to 're-do everything'. While she killed her pilot & was destroyed, she somehow came out of this as Next Exy (NEXY). NEXY is credited for all the events that lead up to DFK. This resurrected form was a regular final boss in DFK.

Hibachi is best known as being the TLB of many DDP titles. However, in the IOS (and Android?) version of DFK, Hibachi is also selectable as a fighter (in Smartphone Mode). This fighter is selectable by beating Hibachi or by entering a code.

Due to this, Hibachi can't relly be considered a ship/doll/fighter. However, the presence of him/her as a selectable ship earns a place in this list. Note the picture to the right represents the classic spiral firepower of this character.

As SDOJ hasn't been translated, my guesses here are poor. The easy part is that she is associated with the Type-B ship and she had a medium-width laser and her speed is average. Her likes are dog samurai (?) and dislikes are cat indecision (??). She was voiced by Kitamura Eri.

Hina is not a playable character in any DDP game. However since she is an Element Doll, she's included here.

Hina was created with Saya as an experiment. They are considered 'sisters' and were designed to help the human race. However, something went wrong and rather than helping, a paradox of destroying humans was created. Hina's mission was cancelled and she was frozen.

Somewhere after this, she emerged from this and became Hibachi. Her likes are life, organisms, plants & flowers. Her dislikes are not making peace and poison.

Leinyan was one of the three original Element Dolls from DOJ and she was a laser-enhanced Element Doll. Her normal shot was narrow and weak but her laser was strong. She could carry up to four bombs, more than Shotia but fewer than EXY.

As per Cave's IOS DOJ page, "Created by individuals that opposed against war, Leinyan is one ELEMENT DOLL that had her "emotion" implemented." (this affects her resurrected form, the stage-4 boss Ray'n in DFK.) She was programmed to save her pilot's life and through battle she would learn about human nature.

As SDOJ hasn't been translated, my guesses here are poor. The easy part is that she is associated with the Type-C ship and while her speed is the slowest of the three main dolls, her shot width is the widest. Her likes are waves and the flow of the river, her dislikes are dried flowers. She was voiced by Mamiko Noto.

The Orchid ship was the ship used by Kikyou & Botan in Akai Katana, the side-scrolling game Cave released in arcades and on the Xbox360. As DDP: Maximum was so heavy on fan-service (not a complaint), it wasn't surprising to see this ship included as an unlockable one. By clearing any version of stage 5 while using the Tigerschwert ship (more fan-service!) would unlock this ship! Orchid includes the same option orb found in Akai Katana but can be a challenge to use in DDP: Maximum.

Piper was created just for the Xbox360 port of DOJ and she was a prototype for a planned mass-production of Element Dolls. She generates more hypers but has a shorter hyper duration and has no bombs (initially). Piper's programming was left incomplete.

Saya was an Element Doll created alongside her 'sister' Hina (Hibachi). She was created to serve her master after the experiments were discontinued. However, after Hina's transformation into Hibachi, she had a special order to destroy her.

She was designed to conceal her inner feelings but it seems she was failing in that regard and she was confused by Hibachi's betrayal. She could never forgive her for that.

Saya is associated with the Type-Z ship and she had a medium-width laser and her speed is average. Her likes are her teddy bear and dislikes include Hibachi. She was voiced by Aya Hirano.

Shotia was one of the three original Element Dolls from DOJ attributed to Shot Type. Her normal shot was wide & strong but her laser was weak. While she was the slowest of the dolls, she also could carry the most bombs.

As per Cave's IOS DOJ page, "Shotia was intended for combat to begin with, leaving all the "emotional" aspects out during assembling. Her mechanical characteristics leads to high devotion toward her mission and will complete her task with consistent composure.

Her ice-cool expression can be seen as if looking down on human beings repeating warfares one after another..."

She was resurrected in DFK as the regular final boss Shooty.

As SDOJ hasn't been translated, my guesses here are poor. The easy part is that she is associated with the Type-A ship and while her speed is the fastest of the three main dolls, her shot width is the narrowest. Her likes are history & tradition, and, quite reasonably, her dislikes include epidemics. She was voiced by Yukana Nogami

A class of fighter from Ketsui, Tigerschwert was brought over to the DDP world on two occasions. The first was in the Xbox360 port of DFK: Black Label. The second was in DDP: Maximum.

A curious, selectable fighter in the 2.0 revision of DDP: Maximum, Uoratou has an interesting background. The last time this character appeared in a Cave game was back in 1998 in Dangun Feveron (Fever S.O.S. internationally). Uoratou was a secret, hidden character in that game. However, he was featured prior to that in a title called Puzzle Uo Poko (link from World Of Arcades) which was also issued in 1998 by Cave. The character's name was apparently created from Uotarou in reverse. This is made evident by the Dangun Feveron OST which features as a BGM name entry track titled, Uotarou Is Working Absurdly. For fans of Cave, this fan-service is always appreciated!
