In the Marvel series What If...? what is the character at the end of episode 1? What is it known as? Does it have any comic book origin or it is created for the show specifically?

I don't believe there is a canonical answer, but a strong possibility is Shuma-Gorath, a tentacled Elder God entity who frequently attempts to invade the world to consume it. As a frequent Dr. Strange villain, it would fit in that they might be teasing him prior to the second film, Multiverse of Madness
Not matching is that Shuma-Gorath is notorious for announcing himself upon arrival.
