Paper Mario: The Thousand-Year Door (2024): Boss #13: Lord Crump

Lord Crump and a battalion of X-Nauts will ambush you shortly after Cortez is defeated, forcing you and Flavio to negotiate with Cortez for the use of his ship. In battle, Crump will summon X-Naut troops in a variety of formations, which can carry out various attacks at differing levels of power. You do not need to defeat the X-Nauts, as they do not count toward finishing the fight and Crump will merely summon more even if you do defeat them. Just keep attacking Crump until he falls.
