The Heliopolitans (the offspring of the Elder Gods Atum & Gaea), rarely took physical form, unlike their later brethren of the Greek & Norse pantheons. For example, the god Khonshu prefers to this day to act via a champion.
One of the (if not THE) oldest of these children was the feline deity Mafdet, who (along with the dragon spirit now known as Shou-Lao) empowered a champion one million years ago, in adventures alongside other gods, hosts, and avatars of the day. She (although gender is fairly arbitrary for a spirit) was an ardent defender against evil, and held sway over the living and the dead, and was known among her worshippers as "the first to be feared".
However, an unknown number of centuries later, Mafdet was approached in her temple in Egypt by an extradimensional sorcerer named Master Khan, who was trapping beings of mystical power in an attempt to boost his mystical might. Indeed, he had already trapped her former comrade in a spell that imprisoned his heart in a cauldron and was now looking for a being of opposite energies (yang rather than yin, in his terms) to balance it out.
Their battle raged, and while Khan did not achieve total victory, he did manage to split Mafdet into male and female parts, trapping the male half in a jade statue of a tiger. The remaining aspect became later known as Bast, and anchored herself to a mound of metal in a nation far to the south, empowering a new champion named Bashenga, the ruler of a nearby tribe.
(Something similar happened to Shou Lao, actually.)
Her other half, almost completely feral, took on a name based on the animal whose form he now possessed, calling himself the Tiger God. Eventually, parts of the statue were broken off by thieves, passing through many hands before coming into the possession of the Ayala family, who were his champions for several years.
(At one point, the statue was reconstructed, but the union was imperfect, leading to the amulets falling off in mid-transit and returning to their last possessor.)
The amulets were recently destroyed, and the spirit of the god himself trapped in a containment vessel, coincidentally by the champion of his other half. One wonders what would happen if those two halves met…
AUTHOR'S NOTE:
In order to keep things tidy, I am assuming that the Iron Fist & Black Panther seen in Avengers 1,000,000 BC are not part of the traditional lineages for those characters, keeping the rest of their histories intact.
I also used the fact that Marvel has rarely had the Egyptian gods show up as active characters to explain why Bast doesn't act in person.
I have not yet decided where Shou Lao came from. Candidates include an offspring of Set or the Egyptian being named Apophis (whose role as enemy of Ra was supplanted by Seth in the Marvel U).
