10 Batman Sidekicks Everyone Forgets

10. The Signal

Perhaps the best known of more obscure Batman sidekicks, the Signal is worth mention because of one crucial thing that anyone who hasn't kept up to date with the Dark Night: Metal storyline will have likely totally missed: namely, that the Signal has superpowers.

In one of the more surprising twists of the year, it was revealed in All-Star Batman #9 that Duke Thomas had some kind of powers, as his eyes glow a bright yellow at the very end of the comic. This would be added upon in Dark Days: The Forge, wherein Duke would learn more about exactly what he's capable of doing - although this is still not totally laid out, despite the fact it could easily be one of the most interesting sidekick storylines in recent history.

Combine this with the fact that the Signal often operates at day time - a time that Batman largely shies away from - and it's clear that Duke is way more important than he's often made out to be.
