- sigh* In the first place this wiki isn't a reference resource on the English language and in the second place consistency of error is not accuracy.
Furthermore, this is what we call 'an argument in bad faith': a proxy argument obfuscating the topic. Regardless of whether the CGs are antagonists or not, the question is whether Steven should be labelled as the 'antagonist' or as the 'semi-antagonist' (sic).
I've given you multiple references and examples showing that he is neither. He's the main character, therefore the protagonist according to every definition of the word.
But, as you've stated that you believe Monster!Steven is the 'antagonist' regardless, I can only assume you're not really interested 🤷♀️ you do you, I guess. Peace ❤️
