Waluigi has been scorned by Nintendo yet again, being left out of the roster of Super Smash Bros Ultimate. However, there is still a chance for Waluigi to get his rightly deserved place in the spotlight. Waluigi should appear in the next edition of Higher Algebra.

Indeed, Waluigi fits naturally into the framework of stable ∞-categories, and would probably have been incorporated long ago were Nintendo not so notoriously protective of their copyright. For example, the discussion of the Waldhausen construction in §1.2.2 generalizes without much additional effort to the WAHldhausen construction. It is also worth noting that a careful treatment of the WAHll finiteness obstruction from the ∞-categorical perspective is sorely lacking from the literature.
