Solomon Grundy appeared in The Batman animated series, voiced by Kevin Grevioux.[61] This version is a zombie created by the working class citizens of 19th century Gotham City to wreak havoc on the rich landowners that polluted the local lake with industrial waste that converted it into Gotham Swamp, and is slimmer and more ghoulish than his Justice League counterpart — it bears a closer resemblance to an actually rotted, desiccated corpse — and he is more of a villain tied to Batman due to being 'born' in Gotham. As seen in the episode "Grundy's Night", the local legend had it that Grundy would again arise on a Halloween night when there was a total lunar eclipse in order to take revenge on the descendants of the rich landowners. Gotham City residents therefore referred to this Halloween as 'Grundy's Night.' However, it was actually Clayface in disguise. Though at the end of the episode, something begins to rise out of the swamp as a moan is heard.
