I going to try something new. Go into Comic Vine vast data base, and choice a Concept at random and see where it takes me...
Today's Concept: Old Power
The Old Power (or Oldstrong Power) is a source of energy derived from a planet that can be wielded and boost the user's abilities to an incredible level, as well as give the wielder Earth-Manipulation abilities and an energy-enhanced strike, similar to that of the Iron Fist.
I kinda know a little bit about this Random Concept choose, I personally read Planet Hulk, where this concept originated and much of the Incredible Hulk: Dark Riegn series where Skaar used the Old Power alot. So here goes.
When the Hunk was exiled to Sakaar he first learned of the Old Power. Throughout the series he'd meet several of Sakaar inhabitants that could use the Old Power, notable were Hiroim and Caiera. Hiroim would later become part of the Hulks Warbound, and Caiera would later become the mother of the Hulk's childern. Both Hiroim and Cairea are now dead, but both passed on the Old Power in different ways.
Hiroim came with the Hulk and his Warbound to Earth as part of World War Hulk. During the war Hiroim used his Old Power to do amazing things but it wasn't until after the War, in World War Hulk: Aftersmash that Hiroim used his Old Power to its true potential. While battling the Leader Hiroim would push his power to the limit to save some humans who are trapped, then with his dieing breath he transfers the Old Power to Kate Waynesboro. She is still in possession of the Old Power.
Caiera, passed he Old Power on to her twin sons, Skaar and Hiro Kala but not with out a price. Back on Sakaar the Hulk is there with his queen, Caiera when she is blown up by the space craft the human's sent Hulk into space with. Unknown to him her Old Power saves her, some how and she and the planet Sakaar gives birth to Sakaar and Hiro Kala.
Sakaar, after surviving on Sakaar, goes to earth where he fights Banner, trying to get the Hulk to come out. He does some of the more amazing stunts of strenghth during his time on Earth. Most memorable is knocking the Juggernaut into the atmosphere with an uppercut. At present Sakaar is still in control of his Old Power and is still trying to be a hero. Hiro Kala, however, leaves Sakaar and goes on a mission to destroy the Old Power until the Hulk comes into outer space to stop him. With the help of Sakaar and the Old Power, the Hulk is able to stop his son's madness, but he is forced to let Hiro die.
The Old Power seems to be able to do almost anything and expounds on the traits of the wielder. It seems to enhance strength and ones resolve. The Old Power still has some mystery but sadly with the new Marvel relaunch coming soon it might be a thing of the past.
