Spoilers
Lancer in Chapter 1
Lancer is the first boss the party meets, and he is King's son. After Ralsei explains the prophecy at Castle Town, Lancer rams him with the bike and introduces himself. A short encounter follows. FIGHT knocks him off-screen at 0 HP. If Kris stalls, Lancer notices the bike is "running out of fuel" and leaves.
He keeps showing up through the Field and the Forest, then teams up with Susie. They fight Kris and Ralsei later, and that fight ends by persuading him or by hurting him enough that Susie worries. The battle on this page is the earlier one: Kris and Susie, the bike, and the line "Lancer busts in!" His father is the Chaos King fight.
The attack
In DELTARUNE, FIGHT uses a cursor on a bar. Z inside the bar deals damage and gives 2% to 6% TP, with the critical hit on the left of the bar. A miss deals nothing unless the target's defense is negative. sei26's instructions match that bar: press Z in time to attack.
DEFEND, in the full game, gives 16% TP right away and cuts damage by about a third. Here the author describes DEFEND as reducing Kris's damage. The bullet box in this project is where the bike attack lands. The frame below is that hit, with the damage number on Kris.
This page stays on Lancer. The battle simulator also lists him among its Chapter 1 enemies, as a survival timer rather than this command menu. Jevil is the secret boss behind the same kingdom.

Not on this screen. The HP row is Kris and Susie. Ralsei joins the later fights, including the Chaos King.

Yes. sei26's instructions are arrow keys and Z. There is no on-screen D-pad in the control list.
