Who is the founder of the TVA Loki?

Created by Walt Simonson and Sal Buscema, the TVA originally paid homage to long-time Marvel writer/editor and continuity expert Mark Gruenwald: the TVA staff were all visually designed as clones of Gruenwald (the classification system for alternate realities—the Marvel multiverse—was devised, in part, by Gruenwald).

Who really controls the TVA?

The TVA is a public corporation governed by a board of three directors appointed by the president with the advice and consent of the Senate.

Why was he who created TVA?

He Who Remains in the comics is the last director of the Time Variance Authority in the Citadel at the End of Time. The “end of time” is merely the end of one iteration of the universe, before the next one begins. He Who Remains created the Time-Twisters and the Time-Keepers with the goal of teaching the next universe.
