Let's see where they come from :
1.
Phoenix 
A phoenix is a mythical bird with a colorful plumage and a tail of gold and scarlet (or purple, blue, and green according to some legends). It has a 500 to 1000 year life-cycle, near the end of which it builds itself a nest of twigs that then ignites; both nest and bird burn fiercely and are reduced to ashes, from which a new, young phoenix or phoenix egg arises, reborn anew to live again. The new phoenix is destined to live as long as its old self. In some stories, the new phoenix embalms the ashes of its old self in an egg made of myrrh and deposits it in the Egyptian city of Heliopolis (literally "sun-city" in Greek). It is said that the bird's cry is that of a beautiful song. The Phoenix's ability to be reborn from its own ashes implies that it is immortal, though in some stories the new Phoenix is merely the offspring of the older one. In very few stories they are able to change into people.

Leviathan (TideHunter)

Leviathan is a sea monster referred to
in the Bible.
In Demonology, Leviathan is one of the seven princes of Hell and its gatekeeper (see Hellmouth). The word has become synonymous with any large sea monster or creature. In classical literature (such as the novel Moby-Dick) it refers to great whales, and in Modern Hebrew, it means simply "whale."
In Satanism, according to the author of The Satanic Bible, Anton Szandor LaVey, Leviathan represents the element of Water and the direction of West. The element of Water in Satanism is associated with life and creation, and may be represented by a Chalice during ritual. In The Satanic Bible, Leviathan is listed as one of the Four Crown Princes of Hell. This association was inspired by the demonic hierarchy from The Book of the Sacred Magic of Abra-Melin the Mage. The Church of Satan uses the Hebrew letters at each of the points of the Sigil of Baphomet to represent Leviathan. Starting from the lowest point of the pentagram, and reading counter-clockwise, the word reads "לִוְיָתָן". Translated, this is (LVIThN) Leviathan.
3.
Lucifer (Doom Bringer).All of us know him.

An ancient myth of the fall of angels, associated with the Morning Star, was transferred to the Devil, as seen in the Life of Adam and Eve and the Second Book of Enoch, which the Jewish Encyclopedia attributes to the first pre-Christian century. In these writings, Satan-Sataniel (sometimes identified with Samael) is described as having been one of the archangels. Because he contrived "to make his throne higher than the clouds over the earth and resemble 'My power' on high", Satan-Sataniel was hurled down, with his hosts of angels, and since then, he has been flying in the air continually above the abyss.
4.
Zeus (Lord of Olympus)

In the ancient Greek religion, Zeus is the "Father of Gods and men" who ruled the Olympians of Mount Olympus as a father ruled the family. He is the god of sky and thunder in Greek mythology.
Zeus was the child of Cronus and Rhea, and the youngest of his siblings. In most traditions he was married with Hera.

Aurel Vlaicu(Gyrocopter)

Aurel Vlaicu was a Romanian engineer, inventor, airplane constructor and early pilot.He was born in Binţinţi , Hunedoara. He attended Calvinist High School in Orăştie (renamed "Liceul Aurel Vlaicu" in his honour in 1919) and took his Baccalaureate in Sibiu in 1902. He furthered his studies at Technical University of Budapest and Technische Hochschule München in Germany, earning his engineer's diploma in 1907.In 1910, after working as an engineer at Opel in Russelheim he returns at Orastie and begins the construction of his first airplane "Vlaicu I". The airplane is extremely well built, stable and very maneuverable, and wins him several prizes at the international contest abroad in the company of other aviatic pioneers from that time, like Rolland Garos.
In 1912, at the international flight competition held in Aspern-Vienna, he is awarded the first Prize of the competition for target launching, and the second Prize for steady point landing. In contrast with other aeroplanes, his aircraft design solutions originality resided in the arrow-shaped body, the front placement of the depth rudder and of the low rudders, the variable elevation airplane wing adopting, during the flight, the form closest to the optimum, a tandem propeller, which, because of their rotation opposite to one another, had a mutual compensation of the torsion couple, the existence of a detachable undercarriage, and of a speed reduction unit between the aircraft engine and the propeller. Open field of view for the pilot, regardless of the course of flight, was characteristic of his own made aeroplanes.
In 1913, he finishes "Vlaicu III", the first all-metal aeroplane in the world. On the 13th of September, he dies at Campina, close to Ploiesti, during a flight with his own airplane "Vlaicu II" over the Carpathian Mountains.

Raijin (Storm Spirit)

Raijin is a god of lightning, thunder and storms in the Shinto religion and in Japanese mythology.
His name is derived from the Japanese words rai (雷, meaning ‘thunder’) and shin (神, ‘god’). He is typically depicted as a demon beating drums to create thunder, usually with the symbol tomoe drawn on the drums. He is also known by the following names:
-Kaminari-sama: kaminari (神, kami, spirit or deity + 雷, nari, thunder) and -sama (様, a Japanese honorific meaning "master")
-Raiden-sama: rai (雷, thunder), den (電, lightning), and -sama (様, master).
Many of us asociate him with Raiden from Mortal Kombat.

Medusa(Gorgon)

In Greek mythology Medusa (Greek: Μέδουσα (Médousa), " guardian, protectress") was a Gorgon, a chthonic monster, and a daughter of Phorcys and Ceto.The author Hyginus, (Fabulae, 151) interposes a generation and gives Medusa another chthonic pair as parents. Gazing directly upon her would turn onlookers to stone. She was beheaded by the hero Perseus, who thereafter used her head as a weapon until he gave it to the goddess Athena to place on her shield. In classical antiquity the image of the head of Medusa appeared in the evil-averting device known
That's all i know but can be a few more if we associate skills , how they look or a parth of name like :
Lord of Avernus(Abaddon)

. Nobody say something about a lord but we have
"Avernus"In the ancient Roman society Avernus was believed to be the entrance to the underworld, and is portrayed as such in the Aeneid of Virgil. The name comes from the Greeks "without birds", because according to tradition, all birds flying over the lake were destined to fall dead. This was likely due to the toxic fumes that mouths of the crater gave off into the atmosphere. In later times, the word was simply an alternate name for the underworld.
