In the space of a few issues of the Superman comic book series, Doomsday battled Superman in a titanic struggle, leading the hero to conclude that the creature would continue to attack relentlessly and endlessly, with no fear or compassion. Matters came to a head in Superman (vol. 2) #75, wherein both Doomsday and Superman beat each other to death in front of the Daily Planet building in Metropolis.[9]
