Edit:

Another liberty I'm taking with the setting is allowing a player to take advantage of the element of Counter Earth seemingly [i]not[/i] having a Spiderman, so I'd allow one of you to take on that role? Titular character, and all, ought to include him/her/them. The added bonus? Rather than be limited to the Nano-suited Spiderman from the series inspiring this, a hopeful player submitting a character as Spiderman could make a unique iteration/interpretation, either from a different reality or one unique to Counter Earth, only recently coming into their powers.

Spotlight would still need to be shared as equally as possible among players, but it [i]would[/i] be pretty cool to have (a) Spider-sona in a Spiderman inspired setting. :P
