Name Ideas for Archangel-like Vigilante...

Hello! I'm developing an Original storyline, set in a World much like ours, but full of Unimaginable things that Happen, with Beings incomprehensible to Human logic, some Super-Humans, some Supernatural, and some that came from the Stars. Translating: a SuperHero World. And among them all, there's one Mortal, with a sustaining life, but living in the Suburb, that decides to make a Difference in the fictional city of Aligheri, and takes the Name of a Mythological and powerful Archangel.

Personality/Appearance and Equipment:

For the People in the day, he is Brave, Inspirational and humble, and help those who are Good and suffer from Misery and violance, but at Night, he is Feared and Cruel to those that choose to do the Wrong, but doesn't kill them. He's very intelligent, and his Leadership abilities inspire those around him. He has the Appearance of a Knight, but with Tactical traits like a Soldier, and two small Metallic skirts on his hip. His helmet has two Horns that make a curve upward on each side of his Face with a Skull-like shape, and metallic fingers on his Feet.

He has grey colored Wings on top of his long black Cape, that are Used as extra artificial body Limbs to help people and support him in combat, much like Tendrils. They can change their weight and structure, from light as a Feather to Heavy as a Metal, they even can cut any material that exist. His suit's color scheme is Black Grey and White, with some Yellow-Golden details, and Under his cape is Purple. His suit is fully made of three fictional Powerful metals that are very Light, Resistant, and Strong (i don't have a name for them).

Even without Powers, he's very effective against Beings way more Powerful than him. With his Intellect and advanced gadgets on hands, he can literally win any battle that may come. Some of his gadgets almost look like Sorcery, but they're just very advanced. He also uses some Weapons, like a Sword that turn into a Double Bladed, a double edged Axe, two arm Cannons with triple barrels, an advanced rounded Shield, and Boomerang-like Knives with a Crescent Moon shape.

References:

Think of him as Batman with his Tech, Vehicles, Gadgets and fear tactics, but with Wings like Sam WIlson's and the Archangels from Diablo, some traits of Optimus Prime's Knight form, violent Methods from Moon Knight, and Doctor Doom's Aura. Also, he uses a male black-grey Fedora Hat with wide Brim. And one of his weapons works almost like Captain America's Shield, but idk which one could work like it.

Main Issue:

So, my main issue here is his Name, and i've already tried to think on a Name for him, but it didn't came anything to me! And my Creativity for names is Terrible lately. So i'm asking if you guys have any Ideas for his Name, Nicknames, titles, and Weapon. If yes then welp... i'm all ears! Have a nice day everyone! :)
