Block

From Jenny Everywhere Wiki

Block was a superhero from Universe Gemini.

Before being killed in the line of duty, Hardcore left behind a number of children: one, Kid Hardcore, was legitimate, while the rest, including Block, Plus, Queensize, Presto 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)

Though seemingly slightly annoyed by their presence, Zed invited Presto and Block alongside several friends of his to a meeting at a café so that he could introduce a new friend, the alien girl Neila, to them. (COMIC: Zed Vs. The Introductions)
