#### Mauler Twins:

Oliver Grayson first meets the Mauler Twins in the nuclear missile silo. Oliver Grayson fights the Mauler Twins as a way to help Mark Grayson, but Mark Grayson orders Oliver Grayson to get away from the battle. One of the Mauler Twins wants Mark Grayson to focus, so Oliver Grayson attacks the Mauler, so that the Mauler can get off of Mark Grayson. The other Mauler prepares to shoot Oliver Grayson, but is reluctant to do so, because Oliver Grayson is a kid. Mark Grayson leaves the battle to go after the missile and orders Oliver Grayson to not fight the Mauler Twins, but Oliver Grayson breaks one of the Mauler Twins jaw.

The Mauler with the broken jaw throws Oliver Grayson in frustration, but Oliver Grayson retaliates by killing the Mauler. The last remaining Mauler attempts to beg for mercy towards Oliver Grayson, but Oliver Grayson kills the last Mauler by punching his head open.

Oliver's purple skin was the result of a lower genetic incompatibility with Viltrumites than with Humans. Because of this, Oliver's growth-rate to become stronger is lesser than Mark's as his Human half is more compatible with Viltrumites.
	+ **Dominant Genetics**: Despite the comparatively lower genetic compatibility, Oliver's developed is predominantly influenced by his Viltrumite genes, hence why he has a more humanoid appearance than insectoid and why his purple skin turned light and creamy in color as he got older. Having inherited his father's dominating genes. 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.

A couple of weeks after, he had the appearance of a 5-year-old. Before he went to fight in the Viltrumite War, Oliver had already had the appearance of a teenager. 10 months away from Earth, Oliver has become an adult. After 6 months leaving Earth again, Oliver has the appearance of an adult male and bared similarity to an adult Mark.. 5 years later, Oliver would bare resemblance to an adult Viltrumite male . Within each age cycle, his aging is slowed down by his Viltrumite DNA. Nolan speculates that Oliver will likely live for centuries, if not thousands of years and still be in his prime.
* **Cybernetic Enhancement**: After his left arm and jaw were destroyed by Thragg they were replaced with cybernetic components.

### Weaknesses
