When the Green Lantern calls for an oath, one doesn’t hesitate to respond. That’s how the 5,000 visitors of the Munich Comic Festival saw it too, as they collectively swore their oath to the green light. The fan community could then immediately witness their newly gained (green) energy online. And now all together:
In brightest day, in blackest night,
No evil shall escape my sight.
Let those who worship evil’s might,
Beware my power, Green Lantern’s light!
Superheroes, never walk alone!
