The red bad guy at the end of the Avengers is Red Skull from Captain America
The previously entered answer, stated above, is wrong. The guy at the end of the Avengers movie is most likely Thanos. You might notice that the guy at the end has more of a purple-ish skin color, and has more of a rounded and fleshed out face; The Red Skull from the Captain America movie has red skin, and has a bony or skull-like face, hence the name Red Skull. Plus if you look at pictures of The Red Skull and compare it with a picture of the guy at the end of the movie, they don't look the same. If you do the same with a picture of Thanos, you will find that they look almost identical.

Thanos was born on Titan, a moon of Saturn, to Mentor and Sui-San. Thanos is born with the Deviant gene and as such resembles the Deviants-the Eternals' cousin race-more than his own people. Although treated fairly by his race, he is mindful of his appearance and becomes distant, only keeping company with his brother Eros (Starfox). During his childhood, he becomes fascinated with nihilism and death, eventually falling in love with its embodiment, Mistress Death. As an adult, Thanos uses bionics and mysticism to become the most powerful of the Titans, and is often referred to as the Mad Titan.
