Like always, I did like Android 18 in Dragon Ball Super.
For most of the series, she doesn’t really fight. We mainly see her be the wife and mother she became near the end of Dragon Ball Z.
I did enjoy the awkward moment between her and Future Trunks.
She does fight during the tournament of power. First teaming up with her husband Krillin, and later with her brother Android 17.
She does sacrifice herself, though not mortally to save her brother Android 17 from being eliminated himself.
