>>109628248>>109628296Not OP but it depends on when and who he fights in Star Vs. People forget that monsters and various demons do get vanquished/killed in Star Vs albeit in a comical and inoffensive way.
>ToffeeIf he had to fight Toffee then by the same asspulls Steven beats him but only by killing Toffee, not by singing to him or "redeeming" him through familial guilt. Similar to Star Vs, Toffee would show some revelation about how Steven needs to bring the gems to an end, probably by making them completely human.
>MinaShe's what most hope Spinel will be. A villain who is adamant in her belief of foreign invaders (monsters/gems) needed a good purging for the sake of Mewmanity. Even though she was depowered we still saw that Mina still kept to her beliefs, even if she was made into a joke because of Nefcy rushing the ending. Mina probably couldn't beat Steven because he'd have more asspulls than Star but she can take several CGs, Lion, and Connie down with her. If her anti-monster sword could be upgraded to negate Steven's healing then she'd probably be the one to make Steven cry the most. He beats her but he loses everyone else he cares about because his plot armor could only protect him, not everyone else.
>StarS1 Star was much more bloodthirsty and would probably go for the kill with glee because she's practically a Madoka Girl. People forget she was petty, cruel, and abusive, especially when around Pony Head and Marco isn't around to be her Jiminy Cricket. She'd laugh at his attempts to cry his way to victory and would bully him with magic if he got in her way. Late S2 to Mid S3 Star could possibly kill Steven only because of her getting even more powerful asspulls than Steven. If the CGs endangered Marco or her family like Toffee did, she wouldn't hesitate to use the evil dark magics or her Super Saiyan Butterfly mode to zap the CGs. Steven might survive but when Star's out for blood, the CGs will take casualties with one of them being shattered.
