I, Doomsday, stayed inside the Sun’s core for a hundred thousand years!

If you are able to ignore the hatred for the US and love for China the MC has even after living for over 100,000 years in a completely different universe, having become a general that led over 100,000 Doomsday-like beings, being one himself, the only one to keep his rationality and only surviving member of all of Krypton, and led his troops in a plan to conquer the universe for Krypton, then it's ok.

There are phrases that just make you want to rip your hair out, the way they refer to Pepper as "the little pepper" and small things like calling Iron Man's suit the metal suit and other things that just makes you want to end it all. Although it is legible, the translation isn't the greatest with a number of grammatical mistakes when it comes to wording and piecing sentences together rather than spelling.

But yeah, major drawback is just this "US bad, China good, China numbah 1" trope that keeps popping up even after all the years the MC has lived. Like, you'd think the MC would be above these mortal views and feeling of patriotism for his previous life's home country, but the MC wants to wipe out all of the US just because they back SHIELD and use them. Because corruption exists....but you know who would never allow corruption in their government.....you fucking guesses it, China.
