Ultimate Ultimate Bussy Cat

Ultimate Ultimate Bussy Cat is the hyper-evolved form of Bussy Cat, and the evolved form of Ultimate Bussy Cat.
==Appearance==
Ultimate Ultimate Bussy Cat is much larger than his default form, now biologically resembling a plane as opposed to a bus like his default form, or a train like his Ultimate form, having an elongated body structure with enormous wing-shaped legs ending with his front paws and four miniature pairs of retractable legs from across his underside, with dark green fur patterned with wavy bright orange stripes spread throughout his body, his jaws and teeth both encasing the exterior of the large window covering his cockpit, featuring a flattened nose and no visible whiskers, and fluffy windows stretching down the sides of his body from behind his enormous pointed ears, and a propeller-shaped blade on the right side of the tip of his tail like that of a helicopter.
Ultimate Ultimate Bussy Cat wears the Ultimate Simplicitrix symbol on his jet engine thrusters, located on the tops and bottoms of his wing-shaped legs.
==Powers== 
*Ultimate Ultimate Bussy Cat retains the abilities of his default form, and his Ultimate form, featuring even greater amounts of speed much more than the two of them combined together.
*Ultimate Ultimate Bussy Cat's newfound flight capabilities and further increased natural speed makes him capable of launching himself into and entering hyperspace travel, not only traveling between celestial objects even faster than before, but with the addition of also traveling between different realms, such as the Null Void and Ledgerdomain.
*Although retaining his body length manipulation, Ultimate Ultimate Bussy Cat's interior is so utterly massive in sheer size alone, with his passengers entering through his cockpit door that drops down from around his back, making his body extension not very necessary in order to hold more, although should he feel threatened, Ultimate Ultimate Bussy Cat can use his body length manipulation in order to expand in size and make himself more intimidating towards his opponents, enabling him to hold as much as entire populations of smaller planets, easily millions if not a few billion.
*Ultimate Ultimate Bussy Cat has retractable legs that can also be used as landing gear, even themselves capable of accessing his enhanced agility and mobility.
*Ultimate Ultimate Bussy Cat can use his sharp propeller blade on his tail in combat, as well the intense heat and winds from his jet engine thruster exhaust, of which he can combine to launch burning air missiles towards his opponents.
* Ultimate Ultimate Bussy Cat now also substitutes his blindness through a gyroscopic sense that allows him to detect gravitational pulls and forces while up in the air, as although his adaptive seismic sense has some use in visualizing air currents, it has very little usage due to his new method of transportation being off the ground.
*Ultimate Ultimate Bussy Cat is immune towards extreme atmospheric pressure and disrupted equilibrium that would normally inflict with him with feelings of dizziness and light-headedness.
*Ultimate Ultimate Bussy Cat has total space survivability.
==Weaknesses == 
*Ultimate Ultimate Bussy Cat's teeth have become vestigial again, no longer capable of ramming due to the risk of damaging the structural integrity of his plane-body and knocking him out of the sky.
*Ultimate Ultimate Bussy Cat still remains completely blind and incapable of properly perceiving his environment from around him, although is now further aided through the new addition of his gyroscopic sensory abilities.
*Ultimate Ultimate Bussy Cat's new method of transportation makes him unsuited for land travel unlike his past two forms, exclusively remaining up in the air.
*Ultimate Ultimate Bussy Cat's hyperspace travel and its ability to travel between different realms similarly requires knowledge about the realms in question before he can visit them.
==Trivia==
*Ultimate Ultimate Bussy Cat is the first Ultimate form OF an Ultimate form, with the exclamation of how such a possibility exists due to the fact that evolution never really stops, meaning such logic would apply towards the Simplicitrix's evolutionary function too.
**Ultimate Ultimate Bussy Cat being regarded and classified as a "hyper-evolved" DNA sample references Ultimate Albedo referring to himself as that of a "hyper-evolved Galvan," during Omniverse, despite the fact that he shows no evidence of what exactly he means by his evolution being "hyper" when compared to the other Ultimate forms that he has access to.
*Ultimate Ultimate Bussy Cat's green and orange color scheme reference the Rustbucket III, with its green coloration coming from its Ultimate Alien design, and the orange stripes coming from its Omniverse design.
*Ultimate Ultimate Bussy Cat's hyperspace travel is stylized like the time vortex effect of the TARDIS from Doctor Who.
*Ultimate Ultimate Bussy Cat, alongside his evolutionary counterparts, is a subtle nod to the 1987 comedy film, Planes, Trains, and Automobiles.
