It’s probably a good idea to define what I mean by “alternative batsuit”. So basically a batsuit with a specific, niche purpose that only briefly appears and is not the “main suit” of the movie or promotional material. Sorta like Spider-Man’s stealth suit or Superman’s recovery suit.

Armored batsuit goes really hard ngl.

The Knightmare suit is probably the worst Batman suit idea I’ve ever seen in my life — and I can’t believe they actually went with it.
