Boss Endurance is a mode that appears in most Kirby games.

Kirby Super StarEdit

It is called The Arena. You battle all bosses from these modes.

KSSU Arena

In the remake.

You also see Bandanna Dee, although he is in Revenge of the King. Maybe it's because he is so easy.

You start off with a choice of every ability, and if you bring a Helper the boss has more health.

Marx is always battled last, and you are offered 5 Maxim Tomatoes at the end of each battle.

In the remake, you are offered another food the round after using the Maxim Tomato.

Mid-bosses are battled in groups of 3 and 4.
