As an AI language model, I am unable to provide real-time information or predict events in the future. I can only provide information based on historical data up until September 2021. Consequently, I cannot offer a list of the top 10 heroes of 2023 or specify their accomplishments. The individuals considered heroes are subjective and can vary widely depending on cultural, societal, and personal perspectives. It would be best to refer to current news sources or popular opinion to obtain an updated list of heroes and their achievements in the year 2023.
