#4 (October 1993), Liefeld conceded disappointment with the first four issues of Youngblood, calling the first issue a "disaster". He explained that production problems, as well as sub-par scripting by his friend and collaborator Hank Kanalz, whose employment Liefeld later terminated, resulted in work that was lower in quality than that which Liefeld produced when Fabian Nicieza scripted his plots on X-Force, and that reprints of those four issues would be re-scripted. Writer and columnist Peter David pointed to Liefeld's scapegoating of Kanalz as an example of Liefeld's failure to take responsibility for his project, and evidence that genuine collaboration with good writers like Louise Simonson and Fabian Nicieza, which some of the Image founders did not appreciate, had previously reflected better on Liefeld's art. Throughout its run at Image, Youngblood and other books published by Liefeld's Extreme Studios were attacked by critics for late issues and inconsistent quality. Although intended for monthly publication, issues #1-3, #0 and #4-5 of Youngblood were published intermittently between April 1992 and July 1993. Four months passed between the publication of issues #3 and #0, and five months between issues #4 and #5. Ultimately, Youngblood #5 was published in flip-book format with Brigade #4 as its flip-side; Liefeld was also replaced with Chap Yaep as penciller. Various other Image Comics series were spun off or previewed in these issues: issue #0 introduced the team leader of Brigade, the story arc in issues #2-5 introduced the main characters and central premise of Prophet, and a backup story in issue #3 introduced the series Supreme. An anthology spin-off series Youngblood: Strikefile began publication in 1993, featuring stories spotlighting various individual main characters from Youngblood. Issues #1-3 (April – August 1993) were flip books, containing three-part stories starring Die Hard and Chapel; issue #4 (October 1993) contained a single self-contained story featuring Shaft, Badrock and Die Hard. A one-shot Youngblood Yearbook (July 1993) featuring the "Away Team" was also published, effectively as an annual. Liefeld solicited writer Kurt Busiek for Youngblood stories in 1993. Busiek wrote detailed plots for three issues and ideas for a fourth, under the proposed title Youngblood: Year One. This was never produced, but the plot lines were revived amid controversy years later. From September 1993 a new title was launched, Team Youngblood, published monthly, pencilled by Chap Yaep. It featured what was formerly termed the "Away Team" with an altered team lineup,
