Indus Valley civilisation (3300 BC-1900 BC) is one of the oldest ancient civilisation in the globe which is believed to have originated around the basins of Indus River. The civilisation was spread on an area of the present day Northeast Afghanistan to Pakistan and Northwest India. This is the most widespread civilisation covering a region of 1.25 million kilometres. Indus valley civilisation along with ancient Egypt and Mesopotamian, was one of three earlier civilisations of the ancient world, and of the three the most widespread. Evidence for an advanced urban culture, sophisticated engineering and technology was found during the excavation making Indus valley as the first urban centre of the region.
Mesopotamian Civilisation
Mesopotamian civilisation is also known as the first civilisations in the globe existed during the period between 3500BC to 500BC. According to the experts, the civilisation originated in the northeast by the Zagros Mountains, southeast by the Arabian Plateau on the area covering present-day Iraq, Syria, and Turkey. The origin of the civilisation dates back to 3500 BC and there is no known proper evidence of any other civilised society before Mesopotamian civilisation. According to the experts, the timeline of ancient Mesopotamia is believed to be around 3300 BC-750 BC.
Ancient Egypt
Ancient Egypt is one of the best examples for the culturally richest civilisations in the ancient world. The timeline of the ancient Egyptian civilisation is held between 3100 BC-2686BC as experts believe that the civilisation coalesced around 3150 BC on the area of present Egypt. The civilisation was originated on the banks of the River Nile. The ever standing pyramids and the Sphinx are the best examples for engineering skills of people of ancient Egypt. Ancient Egypt has given us a number of wonders including ever standing pyramids, the mummies of the ancient Pharaohs, the first solar calendars, Hieroglyphics, and many others.
Mayan Civilisation
Mayan civilisation originated near present-day Yucatan and was spread on an area of Yucatan, Quintana Roo, Campeche, Tabasco, and Chiapas in Mexico, and other areas of the region. The timeline of the civilisation is held to be around 2600 BC-900 AD. The Mayan people are still known for their knowledge of Astronomy. The ancient Mayan civilisation began in Central America from about 2600 BC. The civilisation had a booming population of about 19 million during its peak time. By 700 BC, the Mayans had their own system to write which they applied to carve their own solar calendars on stones. The ancient Mayans were culturally and technologically-rich when compared to the many contemporary civilisations. The Mayans constructed the pyramids bigger than those in Egypt. The sudden disappearance of sophisticated Mayan civilisation is still a mystery for the researchers.
Chinese Civilisation
Chinese civilisation is the fifth oldest known civilisation in the ancient world. The period of the civilisation lies between 1600 BCE and 1046 BCE in the present day China. Experts believe that Chinese civilisation born at Yellow River and Yangtze region and is still known for the invention of paper and silk. Gunpowder, canons, the compass, and many others are some of the major inventions of people of ancient China. The Yellow river civilisation is the base for ancient Chinese civilisation. Around 2700 BC the legendary Yellow Emperor began his rule. Later number of dynasties ruled mainland China till the end of Qing dynasty in 1912 AD with the Xinhai revolution.
Lee Pace joins the voice cast of Prime Video’s Invincible as Thragg in Season 4.
Thragg is the Grand Regent of the Viltrum Empire and the most powerful Viltrumite.
Season 4, due March 2026, sets the stage for the ultimate conflict between Mark Grayson and the Viltrumites.
Lee Pace joins as Invincible’s ultimate villain
Prime Video has confirmed that Lee Pace will voice Thragg, the Grand Regent of the Viltrum Empire, in Invincible Season 4. The announcement was made during a panel at New York Comic Con, which also featured a new teaser for the Burger Mart scenes and confirmed the series’ March 2026 release window.
Thragg is the mastermind behind key characters such as Omni-Man, Anissa, and Conquest. As one of the few survivors of the Viltrumite Civil War, he is dedicated to restoring the empire’s dominance. Superior strength, near-immortality, flight, invulnerability, and advanced healing make Thragg the most formidable threat the series has yet faced.
What Thragg means for Mark Grayson and Earth
Season 3 saw Mark Grayson defeat Conquest, the second most powerful Viltrumite, signalling his choice to resist the empire rather than follow his father’s path. Thragg’s arrival elevates the stakes dramatically. Every conflict from this point will centre on Mark’s efforts to mount a credible defence against the Viltrumites, both on Earth and across the galaxy.
Series creator Robert Kirkman said at NYCC, “Thragg is a monumental addition to the show, who is going to change everything you think you know about the Invincible universe.” Lee Pace described Thragg as a patient but violent character, whose awareness of his power and strategic mind make him a uniquely formidable adversary.
Although Invincible has been renewed for a fifth season, Thragg’s debut marks the start of the series’ true endgame. Mark’s earlier battles were preparation; now the narrative expands to include a larger resistance against the Viltrumites, with Earth playing a central role. Fans can also expect greater involvement from characters such as Anissa and an epic showdown between Thragg and one of Earth’s other powerful metahumans, though specifics remain under wraps.
With Thragg now in play, the series gains momentum, and Mark faces his greatest challenge yet: defending his home and allies against the most dangerous Viltrumite of all.
