Notable appearance: Batman Gotham After Midnight #2
In the recent Gotham After Midnight miniseries by writer Steve Niles and artist Kelley Jones, Batman employs the use of multiple Bat-Nets to render his opponents incapacitated. He has used nets plenty of times in the past, but these high-tech versions are much different than the bulky things he used to carry around.
At first they just appear like tiny mechanical bats that he throws into the air, but within seconds they each shoot out a sophisticated net that tightly wraps around enemies like a spider’s web. Spider-Man might want to look into any sort of legal action he can take here.
