The attacks are taken directly from the cyborg bosses attacks. Don't judge the second attacks name, the Blox Fruits devs made it, not me.
Obtainment
The player must have access to the Cyborg race, the Cool Shades, the Shipwright subclass, and the Guardian boat. If the player meets all of these requirements, the player can head to first sea where they can talk to an NPC hidden in Fountain Island named Super Cyborg, if the player meets all the requirements, the Super Cyborg will challenge the player to kill the Cyborg boss only using M1 attack, once the player has completed this, they can head back to the Super Cyborg where they can purchase the Supa Art for $2,000,000.
Passive
When the player has the Supa Art equipped, they gain large red spherical shoulder pads that have yellow stars that encircle each one of them (size increases with Buddha). The passive is only visual.

Cons
Does not reliably break ken
Can require a lot of skill
Rocket barrage can leave you vulnerable for a bit after the attack is done
Pros
Would be great for PvP because of the high damage and stun
Pretty easy to obtain considering to get it you have to be at least lvl. 2500 (because of the shipwright)
Rocket Barrage can be useful in PvP because of the short immunity to all attacks
The gas from the attack can be great for combos because of the stun and ken break.
Great paired with cyborg because of the instinct disabling and great combos.
