After the 00 Diver Ace was wrecked in Gunpla Duel, Riku carried out a large-scale remodeling, and it was born again as this new Gunpla. Based on Riku's previous experiences as he fought many powerful enemies and journeyed on countless adventures, the concept of this custom build is to add elements of Gundams from other series to the 00 Gundam. In particular, it incorporates designs and functionality from the Destiny Gundam.
Can be stored on the rear waist armor when not in use.
The 00 Sky has four beam shields, two on its forearm guards and two on its shin guards. The two on the forearm guards can be used for basic defense, while the two mounted on its legs can be used to kick beam shots back to the enemy, and are also used in the 'Infinity Shot' special attack.
Special Equipment & Features
A system combining the capabilities of 00 Gundam's Trans-Am System and Destiny Gundam's Wings of Light. It grants 00 Sky tremendous acceleration and speed when activated, and the entire Gunpla turns a reddish hue, with the beam shield units on the arms and legs glowing more brightly, and a pair of Wings of Lights are emitted from its drive units.
Wings of Light
Like the ZGMF-X42S Destiny Gundam and the LM314V21 Victory 2 Gundam, 00 Sky can generate a pair of energy wings from its drive units. The wings can be used to increase the Gunpla's speed, and this effect is further enhanced when Trans-Am Infinity is activated, or to serve as a large energy shield capable of blocking an attack that has the output of five Gunpla. However, blocking such a strong attack stressed the drive units, leading to a minor blow out, but the Gunpla remains operational.
Higher Than Sky Phase
A special state the 00 Sky can assume using the Trans-Am Infinity, its specifics are currently unknown. When activated, the 00 Sky shifts from the usual reddish glow effect of Trans-Am Infinity to a light blue coloration, with the dark blue parts of its body glowing in a lighter blue, and the tips of the forearm guards also separate. Simultaneously, temporary particle rings are produced in the wake of the generation of the Wings of Light.
00 Sky's hand-to-hand combat mode, Riku created it prior to his fight with Tigerwolf. In this mode, the 00 Sky’s backpack and shoulder binders are lowered to the waist level, and this solves a weakness of the Gunpla where the shoulder binders limit the machine’s range of motions. Lash Position also has a lower center of gravity, leading to increased mobility.
A combination special move with the PEN-01M Momokapool. The Momokapool ejects its Petitkapool, and the 00 Sky kicks it like a soccer ball towards the enemy using the leg-mounted triangular device after activating Trans-Am Infinity. The power of the kick combined with the propulsion power of the Petitkapool results in a powerful attack that overwhelmed even the tough armor of the Super Shock Gundam, which is five times stronger than a usual Gunpla's.
Finish Move 01
A special move invented by Riku during his battle against Tigerwolf's XXXG-01S2龍虎狼 Gundam Jiyan Altron. The 00 Sky in "Higher Than Sky Phase" wraps the Buster Sword with the Wings of Light, transforming the weapon into a large green energy blade with tremendous power. A single strike from this blade is able to overpower Jiyan Altron’s ‘Raijin Thunder’ special move, and causes heavy damage to the stage. However, as the 00 Sky is not yet adjusted to use this move, the backlash from using it cause severe damages to the Gunpla. 'Finish Move 01' is a generic name given by GBN, Riku has yet to name it. 
After Riku's battle against Tsukasa Shiba, he was lost as to how to rebuild the 00 Diver Ace, and began revisiting GBN locations and talking to the friends he had made through the game. He then revealed to Sarah his wish to hear 00 Diver Ace's 'voice'. When the two held hands and Riku reaches toward the Gunpla with his other hand, he had a mysterious vision that ended in the silhouette of a Gunpla. Inspired, Riku rebuilt the 00 Diver Ace into the Gundam 00 Sky based on the image he saw, with the assistance from the members of his Build Divers force. He retained the chest scar of the 00 Diver Ace, but covered it with a clear piece, to serve as a reminder of his past battles.
Upon accepting Tigerwolf's challenge to fight him in the Ryukosai, Riku modified the 00 Sky to incorporate the new 'Lash Position' for hand-to-hand combat. Mid-battle during the fight with Tigerwolf, Riku created his very own Special Move in desperation, but came up short as his Gunpla wasn't designed to handle the powerful attack.
