Captain America (2018 series) #699

In the near future Washington of 2025, Captain America is trying to get past the sentries of King Babbington; he battles one large armored guard and discovers he is fighting the Hulk. He tries talking his old pal out of what he's doing but must rely on explosives put in Hulk's face to subdue him. Hulk transforms back to Bruce Banner and explains that he was brainwashed and that only one other superhero survived the blast radiation. Ordering his commandos to protect Banner, Cap and Liang proceed into the enemy stronghold....

King Babbington, a mutated figure who believes he is an elite ruling a city of special people, resents this uprising by the inferiors. He orders his troops to the logical place for Cap to go...

...the castle's power plant. Cap and Liang examine the place and can't figure out the source of the power...until Cap spies Ben Grimm, the Thing. Ben has been personally turning the device that generates the power, in the belief that he is single-handedly keeping the people of the USA alive.

When Cap reveals that Ben has been deceived by the villainous Rampart, he goes berserk, smashing the machinery until Cap calms him down, sending him out to the perimeter wall where he uses a Reed-developed weapon to smash the castle's walls. Cap leads the rebel forces inside and to the throne room to confront King Babbington.

The King, however, uses his mental powers to try to enslave Cap, while mocking the hero's defense of the inferior multitudes. Babbington demands Cap hand over his shield; instead, Cap hurls it and conks the King on his oversized noggin....

What next? Cap is asked. He explains about vigilance—how others will try to seize power in this newly-created vacuum; he offers his services as protector and suggests Liang for leader. But the people want Cap as their leader....
