F-144 Sky Penguin/XF-144 Protocol

The XF-144 Protocol is an alternate hybrid form installed into Bubbles for situations where Buster cannot pilot him for combat.

Overview
Because Buster predicted that in certain situations where he leaves Bubbles alone or situations where it's more effective for both to operate individually rather than as a single individual he created the XF-144 Protocol, a voice recognition-activated program (or by being willed by bubbles) which downloads into Bubbles' brain.

After the program is downloaded Bubbles will instinctively hybridize himself so as to make better use of his metallic body and decrease in size containing his massive weight into a smaller frame, as the engines become hybridized with his muscles and his wings become incredibly sharp Bubbles can now function as a powerful swordsman.

Speed
While Bubbles loses immensely in mobility in this form he is nonetheless incredibly fast with his wings, capable of slicing enemies and the environment into pieces at inhuman speeds.

Power
Because Bubble's arms are extremely sharp in this form he is not able to deliver his power in blunt form making it hard to measure, but while he is unable to cut steel he is fully capable of denting it with a hit of his wings.

Endurance
Because of the sheer density of the metal body he possesses once the protocol activates Bubbles is nothing short of indestructible. It's theorized that if bubbles were to be hit by a sea stone bullet even he would not be dented.

Skill
The protocol downloads into Bubble's brain the appropriate response to a wide range of attacks enabling him to counter and attack in ways best suited without needing to think about them as they happen automatically.
