The team reassembles in the latest trailer for “Avengers: Age of Ultron,” featuring Marvel’s most famous cinematic action heroes battling yet another tough foe.

Ultron is a sentient robot first invented by Tony Stark, a.k.a. Iron Man (Robert Downey Jr.), who turns out to be way more trouble than he’s worth.

Iron Man must gather the old team — Captain America (Chris Evans), Thor (Chris Hemsworth), the Hulk (Mark Ruffalo), Black Widow (Scarlett Johansson) and Hawkeye (Jeremy Renner) — in order to battle Ultron, who amasses an army of his own.

Add in newbies Quicksilver (Aaron Johnson) and Scarlet Witch (Elizabeth Olsen), and there’s plenty for die-hard and new fans to look forward to in Joss Whedon’s newest take on Marvel’s flagship team.

“Avengers: Age of Ultron” will be released on May 1, 2015.
