Gravity pendants

The Gravity Pendants also known as the Core Power Pendants are containers of a Core Power, which collectively contain the superpower of Gravity Manipulation.

They were originally distributed throughout the Council and the Foundation evenly, and created at the behest of the Inner Circle's influence, following the devastating usage of the Gravity power by rogue hero Leech (Eric Kirby's brother), who then enacted terrible changes on the world based on his newfound power.

However after many fights, ambitious assaults and deaths the Council of Evil members Amy,Armageddon,Professor Mobius and Necros possess 1 pendant each while the HERO Foundation possesses one guarded by Eric Kirby(Commander Courage). The last one was hidden somewhere in China, by the hero Titan, who left a trail of clues eventually leading to the Great Wall of China.

The pendants are all then collectively found by Jake Hunter in Collision Course, under guidance of the villanous ex-hero Leech. Through a series of midadventures and strategic activities, he was able to garner all the core power pendants and enact the Gravity Control pendant, being the only one not controlled by its corruptive influence. Along the way, he inadvertently arranged the murder of Amy, killed Armageddon, Mobius and Necros in epic showdowns at their HQs, and accidentally caused the deaths of Kirby and Beth, to name a few casualties. Due to his limited collections when enacting the power (4 pendant strength) at the Great Wall, he created a Black Hole above the Great Wall of China that very nearly destroyed the world (which was concurrently being threatened by NanoMite's reign in Hero.Com Book 4). This was ultimately resolved when he found the last pendant and used the full capability of the pendant to banish the Hole.
