How to unlock the PERFECT! achievement in MARVEL VS. CAPCOM: INFINITE - Definitive Guide
Easiest way to do this achievement is to use Ghost Rider, go into Arcade on the Easiest Difficulty, and spam Forward and Y over and over. This will whip the opponent repeatedly. I suggest you try this early in the Arcade Mode against more melee prominent fighters like Haggard.
Or use Chris Redfield, Down, Down, X to go prone and keep hitting X!

A perfect victory occurs whenever the player or opponent has finished the round with a full health bar without taking damage at least once during the round, be it while guarding (as long as no chip damage is dealt), or attacking the opponent head on while dodging their attacks.
As the description says, you will need to earn a perfect in at least one match in arcade mode or any of the three online modes. Keep in mind that you can also get a perfect if your teammate (who has taken damage previously) has fully recovered their health after you switch characters during the match as long as their red health isn't past the start of their health bar, but if you use the soul stone, you can use its infinity surge to steal health from the opponent until you have completely refilled it while going for this trophy.
