This attack has two variantions.
- Baron gives a very powerful kick in the shape of a banana.
- Baron charges his leg with yellow energy and performs a somersault kick to attacks a soccer.
Spear Victory (スピアビクトリー Supia Bikutorī): Has three variations depending on which function Baron activates from his Sengoku Driver.
- Squash: Has three variations.
- Baron releases a spear-shaped beam of energy from the Banaspear to thrust at the enemy, and slashing them.
- Baron firing serval banana-shaped energy projection in few seconds.
- Baron smashes down his enemy with a giant banana-shaped energy projection from the Banaspear. This version has a Anti-air variant.
- Au Lait: Baron smashes down his enemy with a giant banana-shaped energy projection from the Banaspear. When stabbed into the ground, however, the energy travels along the ground for a bit before rocketing back up in the familiar banana-shaped projecting, skewering whatever is in its path.
- Sparking: Baron stabs the Banaspear into the ground, creating multiple banana-shaped projections which hit an opponent several times from below. This also provides as a defensive wall against incoming attacks.
- Gaim Banana Bullet (鎧武(ガイム)バナナバレッド Gaimu Banana Baretto): After Gaim activates his Sengoku Driver's Au Lait function, he releases a spear-shaped beam of energy from the Banaspear to thrust at the enemy.
- Banana Sparking (バナナスパーキング Banana Supāking): After Gaim activates his Sengoku Driver's Sparking function, he stabs the Banaspear into the ground, creating multiple banana-shaped projections which hit an opponent several times from below.
- Spear Victory (スピアビクトリー Supia Bikutorī): Has two variations depending on which function Black Baron activates from his Sengoku Driver.
- Au Lait: Black Baron charges the tip of the Banaspear with energy before charging towards the enemy.
- Sparking: Black Baron stabs the Banaspear onto the ground, creating multiple banana-shaped projections which hit an opponent several times from below. Unlike normal ones, Black Baron's variant produces purple energy bananas instead.
- In Fresh Orange Arms is Born!, Ryugen turned this form down because it was really hard for him to balance with asymmetrical shoulder pads.
- However, Baron, Gaim and Black Baron appear to balance the shoulder pads with no difficulty.
- When Mitsuzane became the second Zangetsu Shin later on, he seemed to display no problem with balancing the large singular shoulder pad of the Melon Energy Arms armor.
