Hall of Justice

Each line in the puzzle describes one or more fictional characters with a superpower receiving an object that grants that superpower. The first step is identifying the superpower.

• Dumbo has the power of FLIGHT.
• The Flamels and the MacLeods have the power of IMMORTALITY.
• Hercules, the Hulk, and Mr. Incredible have the power of STRENGTH.
• A basilisk and Bizarro Girl have the power of PETRIFICATION.
• Sonic the Hedgehog has the power of SPEED.
• Henry DeTamble has the power of TIME TRAVEL.

Indexing into FLIGHT, IMMORTALITY, STRENGTH, PETRIFICATION, SPEED, and TIME TRAVEL by the number of characters that appear in the corresponding line gives the answer, FOREST.
