Kong's Father

Kong's Father is a gigantic prehistoric ape that was one of the last two surviving members of the Kong superspecies when the Iwi arrived on Skull Island.

Appearance
Kong's Father is identical in appearance to his son, but with a few key differences: his fur is black in color, rather than reddish-brown; his neck is more muscular, and his legs are significantly shorter. Additionally, he, like his son, is covered in numerous scars, but his are more severe: he has a large jagged scar on his torso (that starts at the top of his left pectoral and ends at his roght hip) that reveals some of his muscular tissue, a small scar across his left eye and his left eye even appears to have a collapsed socket.

Personality
While little is revealed of Kong's Father's personality, he is shown to have a fierce disliking of the Skullcrawlers (likely due to them wiping out the rest of his kind).

Despite this ferocity, however, he does have a softer side: when the Iwi first arrive on Skull Island, rather than attacking them on sight, he and his mate simply gaze at them; additionally, when his mate went into labor during the final battle against the Skullcrawlers, he fought even harder to protect her while she gave birth.

Strength and combat
Much like his son, Kong's Father is extremely strong and a capable combatant; a testament to his strength is given when Riccio received a vision of the Iwi arriving on Skull Island, he identifies Kong's Father and Mother as the strongest of the Kong superspecies.

Lack of bodily armor
Like his son, Kong's Father does not have any type of dermal armor, making it easier to hurt him.

Numbers
Despite his great strength, Kong's Father has his limits, and can easily be overwhelmed by sheer numbers. This is best exploited by the Skullcrawlers when he was fighting them off so his mate could give birth.

Trivia
