Avengers: Endgame has finally arrived, and its three-hour runtime is packed full of shocks and surprises. Chief among them was the way the film used time travel to bring back a retinue of previous characters - both good and bad - during various scenes that happened after or during moments in some of the biggest MCU movies. Some of the appearances were expected(looking at you, Agent Carter) but others were pleasant surprises (Alexander Pierce) or complete headscratchers (Harley Keener?).
We put together a list of the biggest surprise appearances from Avengers: Endgame. Which character cameos made you do a double-take?
