Volantern, also known as Wollantern, is Kim Diehl's attack using Jacqueline O. Lantern Dupré. The attack begins with a small explosion in the air from Jacqueline's lantern form, propelling her lantern form rapidly towards the enemy. Next, upon making contact with the target, Jacqueline creates a much larger explosion, which causes significant destructive concussive force and the potential of igniting the target—if they survive the initial blast.
"Volantern" is a portmanteau of "vol" ("flight") and "lantern."
