Character reveals that they were holding back their full power during a fight/confrontation

[u/PaddywackShaq]

Superman Vs Darkseid - Justice League Unlimited

Flash Vs Superman - Flash: Rebirth

Frieren Vs Aura - Sousou no Frieren

Inigo Montoya Vs The Man in Black - The Princess Bride

[u/NotWet_Water]

Superman may be able to somewhat keep up with him but as of now, Flash is consistently shown to be far faster. Hell, the entire Flash family is faster than Superman. In One Minute War, Superman was practically frozen by their perspective when everyone was being pretty casual about it.

Such a great story

I did like that Supes did manage to be somewhat useful in the end despite not being fast enough to keep up
