The Climax Cellphone K-Taros (クライマックス携帯ケータロス Kuraimakkusu Keitai Kētarosu) is a special cellphone that was formed from the sandy remains of the Tarōs upon reacting to Ryotaro Nogami's emotions connecting to the Taros in the afterlife. Each of the buttons on the keypad correlate to a phrase that allows Ryotaro to call up one of Tarōs. Once attached to the Den-O Belt and the code 3-6-9-# is entered, Den-O can transform into Climax Form. The K-Taros can also summon the DenKamen Sword to evoke Liner Form. It can also be used as a normal cell phone, often being used to communicate with the Den-Liner crew.
- 3-2-1 spells Momo-Taro-S (モモ-タロ-ス Momo-Taro-Su)
- 6-5-4 spells Ura-Taro-S (ウラ-タロ-ス Ura-Taro-Su)
- 9-8-7 spells Kin-Taro-S (キン-タロ-ス Kin-Taro-Su)
- #-0-* spells Ryu-Taro-S (リュウ-タロ-ス Ryū-Taro-Su)
- 3-6-9-# spells Momo-Ura-Kin-Ryu (モモ-ウラ-キン-リュウ Momo-Ura-Kin-Ryū). This code allows for Den-O to become Climax Form.
Charge and Up
For Climax Form, when the K-taros was set in the Den-O Belt, the user must press the button of the phone (which has a crest of Den-O), it allows for Charge and Up (チャージアンドアップ Chāji ando Appu) finishers, accessed similarly to Full Charge by swiping the opened Rider Pass across the Terminal Buckle, allowing for one of four attacks.
- In Kick Mode, Climax Form can use Boistous Kick (ボイスターズキック Boisutāzu Kikku) where Rod Form's mask is at the foot, and the two antennaes of the DenKamen serving as blades extending down along the leg in the kick. Den-O then executes a one hit bicycle kick to the target. The most powerful version of this finisher was used in Super Climax Form, Super Boistous Kick (スーパーボイスターズキック Sūpā Boisutāzu Kikku).
- In Punch Mode, Climax Form can use Boistous Punch (ボイスターズパンチ Boisutāzu Panchi) where Ax Form's DenKamen is at the fist, and the blade that is part of its mask is used in the punch.
- Climax Form can use Boistous Shout (ボイスターズシャウト Boisutāzu Shauto) where Gun Form's mask opens like a mouth and releases several homing missiles at the enemy.
- With the DenGasher in Sword Mode, Climax Form can perform an enhanced version of the Extreme Slash. Momotaros refers this as My Finishing Attack, Climax Version (俺の必殺技クライマックスバージョン Ore no hissatsu waza kuraimakkusu bājon) and Our Finishing Attack, Climax Version (俺達の必殺技クライマックスバージョン Ore-tachi no hissatsu waza kuraimakkusu bājon) in reference to the Taros working together. The attack is similar to the normal Full Charge Extreme Slash, the most noticeable difference being the rainbow-colored hue the blade takes upon being charged. This attack is sometimes referred to as the Boistous Slash (ボイスターズスラッシュ Boisutāzu Surasshu).
