Hints
Fast health recovery
Upgrade your health recover and the strongest weapon for the character you are currently using. For example, upgrade the Flash's Whirlwind ability or Wonder Woman's Tiara throwing ability with Damage and Duration boosts. All the characters lose health quickly to most any kind of attacks. It is wise to have a fast recovery of health. Use the Speed Boosts in all the recovery slots.
Batman/Zatanna Portal level: Best route
The shortest route is: Green, Green, Yellow, Yellow. This will take you through that portion in the fastest time.
