Signal

Fresh out of 2022's Modern Age, Signal made their entrance in Robin Infinite #1 under the creative hands of Joshua Williamson, Benjamin Rivière, and Jorge Corona — a debut that immediately placed this character in rarefied company. With appearances spread across both Nightwing Infinite and Robin Infinite, Signal moves through a world populated by some of DC's finest, sharing pages with the likes of Robin, Nightwing, Batgirl, Oracle, and Green Lantern. Still a rare find with only a handful of catalog appearances, Signal is exactly the kind of early-era discovery that dedicated collectors love to get ahead of.
