Terra Grayson

Terra Grayson is a Viltrumite-Human hybrid who was born on Earth. She is the daughter of Mark Grayson and Samantha Eve Wilkins, who later becomes known as the superheroine named Invincible, following her father's ascension to title of Viltrum Emperor.

Origin
Terra was born on Earth, to Samantha Wilkins and Mark Grayson. Sam gave birth to her following her emergency surgery when her leg was dismembered by Robot. Following her surgery and giving birth to their daughter, when Eve had fully recovered, she, Mark and Terra went to her home, where they introduced her to her grandparents. Following the funerals of Kid Thor, Cecil Stedman, Black Samson and Knockout and refusing to help Immortal and Dupli-Kate against Robot, Terra and her parents left Earth for Talescria. As they left Earth, Mark decided to name their child Terra, as she was "their little own piece of Earth".

Powers

 *  Viltrumite-Human Physiology:  Being born of 2 different species, Mark possesses the same physical abilities gifted to him through his alien heritage. Unlike her father however, Terra's powers surfaced when she was just a child.
 * Invulnerability: Terra's skin is far harder than a human's, making her virtually impervious to physical attacks. Despite this durability however, Terra's body can be pierced by those with equal or superior strength.
 * Superhuman Strength: Terra is strong beyond that of normal human levels. This allows her to lift things such as massive warships, cruise ships, falling buildings and other heavy objects with relative ease. So long as she pushes her strength beyond their limits, Terra himself will become stronger.
 * Superhuman Speed: Terra is capable of moving at speeds rivaling the most advanced aircraft, capable of moving from the United States to Antarctica within a few seconds and velocities to ascend into orbit with a few minutes. Much like her strength, Terra usually needs to push her speed levels passed their limits to achieve even faster speeds.
 * Superhuman Stamina: Terra's stamina is beyond that of a typical human. So long as she pushes himself, she can stay in a fight for hours without tiring.
 * Superhuman Endurance: Terra is capable of holding her ground in a fight, regardless of taking blows that would otherwise badly injure or kill a human.
 * Enhanced Lung Capacity: Terra's lungs allow him to hold her breath for long periods of time. This enables her to hold his breath in space for a good 2 weeks.
 * Enhanced Healing Factor: Terra possesses a healing factor, which gives her immunity to virtually every known ailments, imperfections and disorders. This also enables her to heal any kind of injuries she sustained in combat with other enemies, but it depends on the severity of the injury sustained during battle.
 * Interstellar Travel: Like normal Viltrumites, Terra is capable of moving comfortably in space without the need of a starship.
 * Flight: Terra's inner ears possess a complex balancing capability, which enables her to defy the laws of gravity without issue.
 * Decelerated Aging: Terra has the potential to live for thousands of years, despite her hybrid physiology. As she gets older, her aging process gets slower and she could be so much more older chronologically and remain rather young in appearance.
 * Dominant Genetics: Much like other Viltrumites, hybrids like Terra possess the ability to have offspring with other species and her children will then inherit her capabilities, as well as overriding most of the genes her spouse possesses.

Weaknesses

 * Vulnerable Ears: Like other Viltrumites, Mark and other hybrids possess an equilibrium in their inner ears, allowing them to fly. If this is disrupted however, Mark is incapable of flight and is in a state of agony. Though this doesn't necessarily have to be from loud noises, but certain frequencies, which can not only cause their ears to bleed, but possibly kill them as a result.
