Spawn/Batman is an entertaning piece of the dark era that spawned (no pun intended) during the 90s. It tells a story of two heroes teaming up to defeat a common enemy, that is after a big unnecessary fight. Batman seriously have to take courses on diplomacy, eh? 
 For those who ask how did this crossover happened, it simply did, with just a hint of being an elseworld story. 
 Except for the fact that we have Spawn and Batman as protagonists, this comic has nothing much to offer. Like many 80s and 90s comics, it is dark, filled with words and adjectives that would make an emo kid orgasm. Spawn/Batman after all is a 90s comic. The artwork is a blast from the past with all those weird aesthetics in the costume and and exaggerated movements. 
 Spawn/Batman is an okay story, with an edge amongst other okay stories because this is a team up of the Dark Knight and the Hellspawn.
