This is not Groot’s first solo series; I Am Groot, by writer Christopher Hastings and artist Flaviano, was published in 2017 (see “Preview: ‘I Am Groot’ #1”).
Groot’s roots go back to 1960, when he appeared in Tales to Astonish #13, and the character popped up from time to time before Abnett and artist Andy Lanning made him part of the team that survived Annihilation: Conquest crossover and became the new Guardians of the Galaxy.
In addition to film and comics appearances, Groot is featured in an animated series on Disney+ (see “Marvel Movie and TV News Roundup”) and a card game (see “Funko Games Unveils ‘Something Wild! Marvel Holiday Baby Groot”). With the third GotG film due out in May, Marvel is also teasing a “Grootfall” event as part of its new Guardians of the Galaxy series (see “New Core Team for Guardians of the Galaxy”).
