My answer was not accurate enough. According to my knowledge of online literature, there is no description or mention of a 70-year-old woman named "Kang Kang". You might have remembered the name or the plot wrongly. If you can provide more information, I will try my best to answer your questions.
Scones were a type of English express bread, also known as English mini pancakes. It was made from wheat, barley, or oatmeal and had a crispy outer skin and a soft inner core.

In many comic storylines, Kang takes on the role of a timekeeper. His ability to control and manipulate time makes him a significant and complex character.
Kang wasn't typically black in the comics. Usually, his character was presented with other characteristics. However, the comic world is diverse, and there could potentially be an exception I'm not aware of.
Often, you'll find characters like the Avengers in the 'kang the conqueror graphic novel'. Since Kang is a major villain, the superheroes who oppose him are important characters too. Iron Man, for example, might use his technological expertise to try and counter Kang's advanced weaponry. Captain America also plays a role with his leadership and combat skills.
Coming and coming had the same meaning. They both meant that someone or something was about to arrive or happen. However, there were some subtle differences in their usage. Coming is more often used to describe the arrival of an important day, person, or event. It can be used for both physical and imaginary things. Arrival was more commonly used to describe a situation where one was approaching or about to arrive on time, and it was more commonly used to indicate a certain node in time. Therefore, although they had the same meaning, they were used slightly differently in the specific context.
