## General Information

Aliases:

* Kamen Rider Uhoden

Motifs:

* Fairy Tale Creatures
* Lighthouse
* Water Strider

Rider Type: Hero

## Forms

Kamen Rider Uhoden transforms by inserting Beast Hearts into her Shiro Driver-Kai after pressing the button and opening the belt's doors. By closing the doors and opening them again, she can activate that form's **Unchained Hissatsu** (Unchained Certain Kill) finisher.

### Mermaid Tower

*"(Standby loop) Unlock! Kaisho Kaisui! Sakana Mermaid Tower! High Tide."*

First Foe: ???

Mermaid Tower is Uhoden's mermaid-themed default form, accessed by using the Mermaid Beast Heart in the Shiro Driver-Kai. This form represents the Mermaid Fable Tail, known in legend as the **Overflowing Seawater** (*Kaisho Kaisui*).

This form is the most balanced of all Uhoden's forms, other than being much more lightweight and nimble compared to other riders. The Mermaid grants Uhoden hydrokinesis and increased fighting strength while near or around water, with the effect being at his peak while underwater.

* **Sakana Mermaid Unchained Hissatsu Kick**: Uhoden summons water that floats a target around in mid-air to trap them in place. A water spray blast then sends Uhoden flying up towards her foe at high speed. Right before reaching the foe, Uhoden's legs fuse together into a fish tail that she uses to bicycle kick the foe.

Taihoragai finisher:

* **Sakana Mermaid Unchained Hissatsu Sandan**: Uhoden charges up a large bubble-shaped bullet at the muzzle. After shooting it at the foe, it explodes into a swarm of smaller bullets that all converge simultaneously for additional damage. Mermaid personally dubs this attack the **Flash Flood Strike** (*Teppomizu Geki*).

### Fairy Tower

*"(Standby Loop) Unlock! Iyasa Miko! Cho Fairy Tower! First Aid."*

First Foe: ???

**Fairy Tower** is Uhoden's fairy-themed alternative fighting form, accessed by using the Fairy Beast Heart in the Shiro Driver-Kai. This form represents the Fairy Fable Tail, known in legend as the **Healing Shaman** (*Iyasa Miko*).

This form is the weakest of all towers in terms of physical stats, so it must be protected in the middle of intense combat. The Fairy grants Uhoden access to various types of support magic like healing ailments, restoring vitality, spawning magical forcefields, and kinetic blasts to knock foes around. This form can use pink energy blasts to attack foes, but said blasts are very ineffective and used only as a last resort. This form also can sprout pink butterfly-like wings to hover in midair.

This form has one finisher:

* **Cho Fairy Unchained Hissatsu Wave**: Uhoden draws in magical power from all her friends in the nearby area. She then releases this as a massive wave of pink magic at her opponent. Alternatively, the acquired energy can be released as an explosion originated from Uhoden's position. Allies caught in the blast have their attacks and finishers empowered.

### Unicorn Tower

Unicorn Tower is Uhoden's unicorn-themed super form, accessed by using the Uma Mega Beast Heart in the Shiro Driver-Kai while in Unicorn Mode.

### Pegasus Tower

Pegasus Tower is Uhoden's pegasus-themed super form, accessed by using the Uma Mega Beast Heart in the Shiro Driver-Kai while in Pegasus Mode.

## Equipment

**Devices**

* Shiro Driver-Kai - Transformation device
* Beast Hearts - Transformation trinkets

**Weapons**

* Taihoragai - Uhoden's primary weapon

The Riptide Pumping Gun Taihoragai is a firearms weapon designed to resemble a conch shell and a singing mermaid. Uhoden can power up the energy shots of this weapon by pulling the ripcord, announcing "Rigan-ryu!". Inserting a Beast Heart into the weapon activates a Unchained Hissatsu (Shot) finisher. The name of this weapon is a combination of taiho (cannon) and horagai.

## Etymology

Isana is a Japanese female given name. The kanji used here translate to "courageous fish". The name is an obsolete Japanese word for the whale, often replaced in modern times with *kujira*. The name also sounds similar to the Japanese word *isamu*, meaning "brave".

Mifune is a Japanese surname. The kanji used here translate to "beautiful boat". Interestingly, the first kanji can also be read as *gyo*, which is Japanese for "fish".

## Trivia

* Uhoden's Rider name is a combination of *uo* (Japanese for fish) and *hoden* (Japanese for an electrical discharge, written with the kanji for setting free).
