Monstar

From the Super Mario Wiki

Monstar getting his dazzling yet incredibly weak attack ready.

Monstar was a ghost-like monster that attacked those entering Starborn Valley in Paper Mario. When Mario and his friends first encountered it, Monstar looked like a tough boss. However, Monstar was really nothing more than a bunch of Star Kids trying to protect their home. When Monstar was about to attack, it would make a huge light show with amazing special effects. However, the attack deals only 1 damage point.

The battle was really simply moving the plot along than anything else, but Monstar still gives a good amount of star points.

Also notable about the battle is that the Monstar was invulnerable to Star Spirit attacks.
