These tasks can be addressed in any order:

Prose

  • Focus article on the character Sonic, and his creation and evolution. Reduce discussion about the games in general
  • Edit sections from an out-of-universe perspective where possible.
  • Copyedit sentences with redundant words. (See: How to satisfy Criterion 1a)
  • Replace references to concept-mobius and ghz with suitable (quoted) references using {{cite video game}} where possible.
  • Remove fancrufty comments about speculation and fan tastes. (e.g. is Shadow or Metal Sonic more popular, etc.)
  • Remove original research. (Metal Sonic's current location, reasons behind talking, etc.)
  • Reformat external links in the text as footnote references.
  • Clean up the article to use the same person, in particular, do not intermix you/we.
  • Use the dash guidlines consistently.
  • Use consistent punctuation.
  • Add Ryan Drummond to the "Voice portrayal" section. He was the official voice of Sonic for six years and yet he's mysteriously absent in this section.
  • Remove pointless lists.
  • All plot should be written in present tense.
  • Add overall article template for all Sonic character articles for uniformity
  • Remove the fact that he is uninterested in martial proposals from Amy Rose. You never know...
