By request, here is the summary of one of my currently running Challenger campaigns:
Episode 1: Adventure 1 Reap Tracker and Cow Bell Campaign.
The two heroes are a super-man look-alike named Cow Bell instead of Kal-El and a hunter/tracker named the Reap Tracker who never reveals her true name to anyone.
The players used an outdated version of Challenger to give themselves super powers and made an NPC for their party who is a first level healer/pirate who has infinite uses of the Raise Dead power.
The evil tyrant king of Am requests the players help in rooting out assassins in his court. The players show up and stop an assassination attempt in the throne room. They resurrect the assassin and find out that it could be either the court wizard or the high priest who is responsible. The court wizard is Selky the Illusionist.
Meanwhile, Cow Bell is seeking a blue magical stone from his people lost somewhere in the city. They find the stone and his people show up to steal it from him. When they return to the castle one of the king's three daughters is dead. They resurrect her and suspicions fall on the High Priest.
The players attack at midnight on the rooftop and find out the High Priest has the stone. The evil wizard of the court attacks the High Priest and they discover the king himself is evil as well. The Reap Tracker gets a huge dragon somehow and there is a battle against Selky's illusions which the players lose and still survive. They crash the dragon into the castle and defeat the evil king.
Cow Bell's Kryptonian Uncle Larry takes over control of the kingdom and the two heirless princesses who are still alive (one died under the bed somehow and didn't get resurrected) follow Cow Bell around like groupies.
As reward, the Reap Tracker now has a huge dragon which can turn into a hippogriff or a horse at will and only needs to eat one piece of silver a day to stay alive. It can also breath: fire, acid, and ice and travels at 1,000 miles per minute.
End of Adventure One.
