Thragg kills him in response. Mark avenges his brother's death by killing Thragg's son. Eve heals Terra's leg, and joins Mark in driving Thragg and his daughter away.[9]

Character Powers and Equipment

Powers and AbilitiesEdit


  • Thraxan/Viltrumite Physiology: Oliver is a Thraxan/Viltrumite hybrid and his Viltrumite heritage gives him access to many abilities as well as Thraxan ability. Oliver's purple skin was the result of a lower genetic incompatibility with Viltrumites than with Humans. Because of this, Oliver's potential to become stronger is lesser than Mark's as his Human half is more compatible with Viltrumites. Oliver is granted the following powers from both his parents.
    • Dominant Genetics: Oliver developed his dominant genetics from his father, Nolan Grayson, hence why he has a more humanoid appearance than insectoid. An example being Oliver's purple skin fading away as he got older. Were Oliver to mate with an alien being with a different physiology than his own, they would likely inherit his traits more than the mother's species.
    • Accelerated Learning: Because of his Thraxan heritage, Oliver is able to gather and assimilate any kind of knowledge and understand it fully and instantaneously.

He is capable of learning, analyzing, memorizing, understanding, and mastering limitless amounts of information, knowledge and skills and immediately utilizing them without effort. He intellect enables him to learn and master anything he comes across of. He can do this so quickly his special teacher couldn't keep up with his learning capabilities, and were more impressed by his massive intellect than his other abilities. With this ability, he can easily master languages in an hour or master a lifetimes worth of knowledge and academics within a few days. Oliver also has an enhanced memory because of this power. He has remembered everything that has happened in his life from birth until death.
    • Superhuman Strength: Due to his Viltrumite heritage, Oliver is granted strength beyond Human levels, whose upper limits are unknown as Viltrumite. He was able to easily kill the Mauler twins. He has the potential to become stronger, but not as much potential as Mark due to his mother's Thraxan heritage not being as compatible as humans
    • Superhuman Endurance: Due to his Viltrumite heritage, Oliver is granted limitless endurance and stamina.
    • Superhuman Speed: Due to his Viltrumite heritage, Oliver has speed beyond Human levels. His exact speed level is unknown, but definitely faster than sound. His senses are also enhanced, which allows him to observe more and as well as perceive reality at high speeds.
    • Invulnerability: Due to his unique molecular structure he has an indestructible and impenetrable anatomy, making him virtually impervious to all forms of physical harm, injury or pain.
    • Enhanced Healing Factor: Due to genes he has inherited from both of his parents, Oliver can restore from injuries much faster than humans. He was able to regenerate from the injuries he sustained during the Viltrumite War(broken jaw, dismembered arm) within a few weeks.
    • Self-Sustenance:Oliver has the uncanny capacity to live entirely self-sufficiently, doesn't need as much sleep as a normal human would.[10]
    • Interstellar Travel: Oliver can survive and function in outer space without aid. He is able to survive and function in any environment.
    • Flight:Due a complex balancing system located in their inner ears, Viltrumites have the ability to fly.
    • Decelerated Aging: Because of the genes he inherited from both of his parents, Oliver's aging process fluctuate depending on the time passed. Within each age cycle, his aging would be slowed down by his Viltrumite DNA. A Thraxan's lifespan is about 9 months while a Viltrumite can live for thousands of years. When he was about 2 months old, he had the appearance of 2 year old human. A couple of weeks after, he had the appearance of a 5 year old.[11] Before he went to fight in the Viltrumite War, Oliver had already had the appearance of a teenager. Ten months away from Earth, Oliver has become an adult.[12] After six months leaving Earth again, Oliver has the appearance of an adult male and bared similarity to an adult Mark.[13]. Five years later, Oliver would bare resemblance to an adult Viltrumite male [14]. Nolan speculates that Oliver will likely live for centuries, if not thousands of years and still be in his prime.


Short-Tempered: Oliver has indeed lost his temper beofre, notably resulting in the apparent death of the Mauler Twins. [15]
