The animated debut of Sam Wilson’s Cap (to be voiced by MCU vet Anthony Mackie) is noteworthy, in that across the 18 What If…? episodes that have thus far dropped — beginning in August 2021 and as recently as Dec. 30, 2023 — the animated anthology had yet to incorporate the new Captain America, who officially suited up back in April 2021 (in The Falcon and the Winter Soldier‘s Disney+ finale).

Explaining said hold-up, What If…? head writer A. C. Bradley told ComicBook.com’s Phase Zero podcast, “we were writing Season 2 as The Falcon and The Winter Soldier paused shooting and the scripts were being re-written because of other things…. So, we couldn’t touch it because … you let the character live in live-action first and then go play in the multiverse.”

Having made his star-spangled debut in The Falcon and the Winter Soldier, Mackie’s live-action Captain “Sam Wilson” America will next be seen headlining Captain America: Brave New World, which finds Harrison Ford succeeding William Hurt as Thaddeus ”Thunderbolt” Ross and is due out Friday, Feb. 14, 2025.
