Hellgrammite (Roderick Rose) is a fictional character, a supervillain appearing in DC Comics. He first appeared in The Brave and the Bold vol. 1 #80 (November 1968).

An entomologist named Roderick Rose, the Hellgrammite subjects himself to a mutagenic process that transforms him into a grasshopper-like humanoid insect. He possesses superhuman strength and leaping abilities, the power to secrete adhesives and weave transformative or imprisoning cocoons, and a durable exoskeleton (Curiously, he does not resemble an actual hellgrammite, the larval form of the dobsonfly). A number of his schemes revolve around transforming others into weaker, subordinate versions of himself, leading to clashes with Batman and the Creeper in Brave and the Bold #80, and with Green Arrow and the Black Canary in World's Finest Comics #248-249.

In the Post-Crisis DC Universe, the Hellgrammite returns as a recurring foe for Superman, first encountering the Man of Steel after being hired (by then LexCorp board member George Markham) to kill Lex Luthor. During the Underworld Unleashed crossover, he makes a deal with Neron, trading his soul in return for increased physical powers and an improved ability to transform others into his larvae. In a crossover special, Underworld Unleashed: Patterns of Fear, it was stated that he had once used the alias Robert Dobson. The special also confirms that his Pre-Crisis history is largely intact.

Although there were rumors of Hellgrammite's death as a member of the Suicide Squad during the Imperiex crisis, it was instead a similar villain named Larvanaut who died. He has been seen alive One Year Later, still a member of Superman's rogues' gallery, acting as an assassin for Intergang.

Hellgrammite has not been a contender in any CBUB matches.
