Presto
From Jenny Everywhere Wiki
Presto was a superhero from Universe Gemini, who evidently had stretching-based powers.
Before being killed in the line of duty, Hardcore left behind a number of children: one, Kid Hardcore, was legitimate, while the rest, including Presto, Plus, Queensize, Block and Zed Hudson, were half-siblings by as many different mothers. However, all inherited superpowers from their father, and later attempted to continue his legacy, with the exception of Zed, who preferred a normal life. (COMIC: Zed Vs. The Backstory)
