Cobra Form (コブラフォーム Kobura Fōmu) is Evol's primary and default form accessed with the Cobra and Rider Evolbottles. Evolto labels this form as "Phase 1" (フェーズ1 Fēzu Wan).

As Evol, Soichi/Evolto possesses tremendous power, as the Evol Driver allows him to tap on the full power of the Pandora Box. His perimeters blow far past Grease, Rogue, and even Cross-Z Magma by a small margin. He also surpasses Build's RabbitRabbit and TankTank forms, though he loses to RabbitRabbit by maximum jump height and running speed, and TankTank by maximum kicking power.

Despite these small disadvantages, he still possesses abilities that are almost impossible to counteract, including teleportation and generating energy in his hand to perform an energy blast. He is also able to attack in extremely high speeds and block attacks quite easily, as shown during his first fight with Rogue.

His Evol Cobra Head (EVO-コブラヘッド Ebo Kobura Heddo) contains the Xeno Head Armor (ゼノヘッドアーマー Zeno Heddo Āmā) which strengthens its durability within each Phase. Between his EVO Twin Eye Cobra (EVOツインアイコブラ Ebo Ai Kobura) lies the Master Planisphere (マスタープラニスフィア Masutā Puranisufia), a device that allows him to determine which celestial body is his next target and formulate the suitable method of destroying it.[1]

In this form, Evol's armor parts are:

  • EVO Cobra Shoulder (EVOコブラショルダー Ebo Kobura Shorudā): A pair of shoulder armor that allows him to improve attack accuracy. Each has a built-in miniature plant that secretes toxic gases as enhancers of the user's ability.[2]
  • Menace Rush Arms (メナスラッシュアーム Menasu Rasshu Āmu): Evol's arms. Through an unknown substance that filled his suit, Evol's strength and speed are enhanced. By himself, Evol can manipulate a special aura that can move objects at will or detain his opponents.[3]
  • EVO Xeno Vader Gloves (EVOゼノベイダーグローブ Ebo Zeno Beidā Gurōbu): Enhanced combat gloves that allows him to create strong punches by manipulating nearby space.[4]
  • Menace Rush Legs (メナスラッシュレッグ Menasu Rasshu Reggu): Evol's leg units. Through an unknown substance that filled his suit, Evol's strength and speed are enhanced. By himself, Evol can manipulate a special aura that allows him to move objects or run at a tremendous speed.[5]
  • EVO Xeno Vader Shoes (EVOゼノベイダーシューズ Ebo Zeno Beidā Shūzu): Evol's combat shoes. Each can perform kick attacks by manipulating nearby space.[6]
  • Xeno Chest Armor (ゼノチェストアーマー Zeno Chesuto Āmā): Chhest armor which compresses and produces unknown substances within the Evolbottles. Said armor is stronger than any material on Earth and its durability increases within each Phase.[7]
  • Armilla Reactor (アーミラリアクター Āmira Riakutā): An Armillary sphere-themed conversion furnace which converts the unknown substance within Evolbottles into strong destructive energy. By completing all Phases, it can demonstrate its true ability.[8]
  • EVO Omniverse Suit (EVOオムニバーススーツ Ebo Omunibāsu Sūtsu): An enhanced battle suit that can emit blocking energy field, allowing Evol to protect himself from enemy attacks or carry out planetary destruction safely. It can also draw out the user's hidden ability and strengthen them based on the Phase.[9]
  • EVO Material (EVOマテリアル Ebo Materiaru): Golden armor parts on Evol's body. They can amplify Evolto's special abilities, empower wave attacks, generate annihilation poisons and allow warp teleportation.[10]

Carried over from from Blood Stalk, Evol wields the Transteam Gun and Steam Blade in this form. He is also able to wield any of Build's weapons if he inserts the corresponding Fullbottle into the Evol-Driver along with Rider Evolbottle.

This form has three finishers:

  • Evol Driver Finishers:
    • Evoltic Finish (エボルテックフィニッシュ Eborutekku Finisshu) This finisher has two variations:
      • Rider Kick: Evol generates an energy star map beneath his feet that then transforms into a dark red and dark blue energy galaxy that flows into his right foot before delivering an explosive kick.
      • Rider Punch: Evol delivers a flaming punch.
  • Steam Rifle Finishers:
    • Steam Shot (スチームショット Suchīmu Shotto): Evol channels the powers of a Evolbottle/Fullbottle and performs a powerful steam blast attack.
      • Cobra Evolbottle
        • Elek Steam: Evol shoots a red and blue homing shot coated in electricity
  • Evol Driver + Hawk Gatlinger Finisher:
    • Kikanhou Finish/Full Bullet: Evol inserts the Gatling Fullbottle into the Evol Driver and turns the crank, summoning the Hawk Gatlinger. He then spins the Revol-Magazine of the Hawk Gatling and fires a stream of large energy hawks.

Dragon Form (ドラゴンフォーム Doragon Fōmu)[11] is Evol's Cross-Z-based form accessed with the Dragon and Rider Evolbottles. Evolto assumes this form while he is in possession of Ryuga Banjou and labels it as "Phase 2" (フェーズ2 Fēzu Tsū).

This form grants higher punching, kicking, and jumping power power than Cobra Form, although it is slower by a very small margin. As Ryuga also possesses the ability to use the Pandora Box, Evolto is still able to access the entirety of Evol's power.

Evol's weapon in this form is the Beat Closer.

This form has two finishers:

  • Evol-Driver Finishers:
    • Evoltic Finish (エボルテックフィニッシュ Eborutekku Finisshu): Evol coats his hand in dark blue flames before delivering a punch that projects an energy Chinese Dragon upon impact.
  • Beat Closer Finishers
    • Smash Slash (スマッシュスラッシュ Sumasshu Surasshu)
      • Dragon Evolbottle: Evol delivers a powerful slash covered in red and blue flames.

In this form Evolto has weaker punching power than Cobra and Dragon Form while his kicking power is slightly better than Cobra Form, but still weaker than Dragon Form. However, his maximum jumping height and running speed have increased dramatically, surpassing both of his previous forms.
