Ultimate Aegis

Ultimate Aegis (ウルティメイトイージス) is a set of armor created by Ultraman Noa. Originally the Shield of Baradhi (バラージの盾), it was converted into its current form and bestowed to Ultraman Zero out of everyone's hopes for resisting against Belial's forces.

Of course, the Ultimate Aegis is likely based on Noa Aegis, a pair of retractable wings used by Ultraman Noa to travel between dimensions.

Ultraman Zero The Movie
The Shield of Baradhi was created by Ultraman Noa at some point of time, where it was placed into a statue of him underneath the Mirror Planet. A shard from the shield was craved, which took the form of the giant's energy core and picked by Hiro, whom would give to his son Nao.

When Noa's universe is under attack by Belial's Army, Run (Ultraman Zero), Nao and Emerana tried to search for the shield and after going through multiple obstacles, they manage to find it. Recognizing a missing piece, Nao placed his necklace (which was the craved part of the shield) on the shield but in a twisted turn, it crumbled to dust. Eventually, Nao had know what was the true purpose of the shield and after encouraging the remaining fleets that resisting Belial's reign, Ultraman Noa visits Zero in his afterlife and revive him, granting the true Shield of Baradhi, which transforms into Ultimate Aegis. After Zero's battle with Belial is over, the Ultimate Aegis was kept inside the Ultimate Bracelet and utilized again by Zero whenever he needs an inter-dimensional travel.

Ultraman X
Using the data of Ultimate Zero, a Cyber Card would be manufactured, which grants Ultraman X a replica of the Ultimate Aegis.

Powers and Abilities

 * Dimensional Travel: Like Noa's Noa Aegis, Zero can use the Ultimate Aegis to travel between universes and probably dimensions as well, however this drains its power and leaves the Ultimate Zero form unusable for a period of time. He can also travel with passengers (all of Ultimate Force Zero).
 * Ultimate Zero Sword (ウルティメイトゼロソード): From the blade on his right arm Zero can summon a blade of energy whose length he can choose, used to slice through Belial's planet size ship. The normal blade itself can be used as a weapon and is strong enough to pierce the body of Kaiser Darkness Belial.
 * Final Ultimate Zero (ファイナルウルティメイトゼロ): The Ultimate Aegis' final attack has it take the form of a bow with strings made of energy, when Zero pulls it, the construct charges with massive amounts of energy and launches itself to the target. Used to defeat Arch Belial, ending the evil Ultra's threat forever. However, this attack exhausted Zero greatly.
 * Final Ultimate Zero Trinity (ファイナルウルティメイトゼロ・トリニティ): A stronger variation of Final Ultimate Zero it was first used on Gigant Zetton. It augmented with Ultraman Dyna and Cosmos' energies.
