Dr Manhattan after leaving his home universe and came across a new universe where there was a formula developed during World War II by a Nazi scientist who jumped ship to the US in exchange for a pardon; creating his own company and used the formula to create lesser superhumans than him. The superhumans became instant celebrities (not unlike Adrian Veidt who profited off his own alter ego Ozymandias after going public) working exclusively for the Nazi's company Vought who held incredible power throughout the US and the resources and wealth to cover up the activities of their popular heroes or to spin the stories when they do reach the public eye.
A group led by William Butcher was dedicated to fighting and exposing Vought's 'superheroes' and their corruption; particular with their premiere team the Seven and their field leader the being known as the Homelander.
He could help this group with his great power but saw no need to; he always so the future and the point where Vought would meet it's downfall would come. Especially thanks to the Homelander whose bullying manchild nature and short sighted thinking would inevitably make his downfall; unable to come up with a way to preserve his image and reputation and spot on top forever. Most he could do was delay and delay.
He just stood on top of the building where he entered the universe from contemplating as he looked to everything happening with his abilities. The Homelander flew down next to him and went up looking all casual. He knew of trillions of ways to dispose of him easily but waste the effort; it would be no different than just a human crushing an annoying ant.
"Hello there; I know you have just been standing there not talking to someone with your dick out and it's kind of creepy... I don't know what your power is but people are now grossed out and annoyed and I have to deal with you. So how about you agree to cover yourself and come with me." Homelander spoke with a smile as he walked up to him.
So easy to just use a simple thought and eradicate Homelander's atoms all together; no trace of him would exist at all.
But why waste on what is little more than a schoolyard bully with the maturity of a toddler; Edward Blake would find the joke of this entire universe amusing but he didn't.
Dr Manhattan continued to ignore him and Homelander getting impatient grabbed his wrist but the energy that his body was made of scorched through his glove and burned him. Homelander yelled out in pain and furiously began blasting at him with his heat vision.
"WHAT THE FUCK DID YOU DO TO ME? ANSWER ME, YOU BLUE SKINNED DICKBAG!" Homelander snapped but even at his most powerful; it didn't even tickle Dr Manhattan. Not even the smartest man in Dr Manhattan's home universe was capable of killing him; this test tube baby couldn't hurt him.
Homelander then roared like a wounded animal and attached with his fists and only succeeded in the energy of his body being destroyed.
Dr Manhattan decided that he grew bored of this universe and left for another; this was a waste of time.
The award for hardest character to write a perspective for goes to Dr Manhattan!
