Trailer-Hou



The Trailer-Hou (トレーラー砲) is Kamen Rider Drive's rifle-like Shift Car weapon utilized when he assumes Type Formula, though he can also wield it as Type Tridoron. It first appears in episode 22.

Like the Handle-Ken and Door-Ju, Shinnosuke names this weapon based on what it resembles: a semi truck, with the trailer section consisting a lot of its bulk. Similar to the Shift Cars and Signal Bikes, the Trailer-Hou is also sentient where it is powered by a specialized Core Driviar called the Core Driviar-TH (コア・ドライビア-ＴＨ).

Usage
The Trailer-Hou can interchange between its Trailer Mode (トレーラーモード) and Cannon Mode (大砲モード) simply by pulling down the Flame Rear Grip (フレームリアグリップ).

In Trailer Mode, the Trailer-Hou not only houses Shift Formula inside of its Shift Container Barrel (シフトコンテナバレル), but is spacious enough to contain all of the Tire Exchange Shift Cars as well. It also utilizes a small visor called the Trailer Searcher (トレーラーサーチャー) for various purposes: searching for either Drive or Roidmudes, generating tracks in midair (being so huge, the Trailer-Hou has to generate three lanes worth of Shift Car tracks), and firing bullets from its front sides. While moving, its Generator Chassis (ジェネレーターシャーシ) tires can provide protection from Super Heavy Accelerations and its Wall Metal Body (ウォールメタルボディ) hard body can resist multiple impacts and damages.

In Cannon Mode, the Trailer-Hou can fire high output blue energy blasts. If Drive loads a Shift Car into its Shift Landing Slot (シフトランディングスロット) on top of the barrel, it announces the loaded Shift Car's name (either the form name of a Type Change Shift Car or the last name of a Tire Exchange Shift Car, though Type Formula-esque Tire Exchange Shift Cars follow "0[number of Shift Car and Shift Car name]) followed by "Hou" (砲) and allows him to fire other colored energy projectiles based on said Shift Car.

 * Shift Speed: Speed-Hou (スピード砲)
 * Shift Technic: Technic-Hou (テクニック砲)

Finishing attacks
The Trailer-Hou has two Rider Shooting Full Throttle finishers, each corresponding to one of Drive's strongest Types. To activate them, Drive must load up to two Shift Cars into the Shutter Gate Panel (シャッターゲートパネル) within the Shift Container Barrel, which causes the Side Gauge Window (サイドゲージウィンドウ) to display the word "FULL" once it is completely loaded, before he pulls the Full Throttle Trigger (フルスロットルトリガー).
