Marvel's press release stated that Marvel Next was "not a new line or imprint" but rather "a collection of titles" intended to "spotlight young characters.
"[1][2] Like the Tsunami imprint before it, it aimed to attract young readers.
The titles were set in the Marvel Universe and most of them (Araña: The Heart of the Spider, Young Avengers, Runaways and Amazing Fantasy) had connections to pre-existing titles, taking advantage of settings, characters and events from previous stories.
Of the series that did carry it, only X-23 and Araña Heart of the Spider displayed it for their entire runs.
The logo was used from March 2005 through February 2006, exactly matching the run of Araña, imprint's longest lasting series.
