Marvel's new Thunderbolts* Super Bowl trailer offered a small tease of the new villain this ragtag group of super-team misfits and antiheroes must unite to face. However, the spot that aired on live TV was just a tease of the full-length trailer that dropped online.

There's a big threat wreaking havoc on the world, and as "Val," a.k.a. Contessa Valentina Allegra de Fontaine (Julia Louis-Dreyfus), declares before a hearing, "The Avengers are not coming." So they need reinforcements.

Val teams up Yelena Belova (Florence Pugh), Bucky Barnes/the Winter Soldier (Sebastian Stan), U.S. Agent/John Walker (Wyatt Russell), Alexei Shostakov/Red Guardian (David Harbour), Ava Starr/Ghost (Hannah John-Kamen), and Antonia Dreykov/Taskmaster (Olga Kurylenko) to face this threat… but who is it?

Julia Louis-Dreyfus says Marvel's Thunderbolts* will finally reveal Val's 'entire plan' (exclusive)

The mystery villain is a big part of the new trailer, though we use the term "mystery" loosely. [Warning of potential spoilers ahead!] All signs point to this figure — whom we only see from the back or off angles to disguise his identity — being Sentry, a fearsomely powerful individual. We do hear his voice in the footage, and it is so clearly that of actor Lewis Pullman, who plays the character identified as Bob.

Multiple clues throughout the marketing campaign for the upcoming film heavily suggest that Bob is really short for Robert Reynolds from Marvel comics, and his alias is — you guessed it — Sentry. The shots of this shadowy figure wearing a cape only support this theory.

"You thought you were gonna be some great saviors?" Pullman's Bob says as he easily grabs Bucky by his vibranium fist before ripping off his entire arm. "You can't even save yourselves."

Louis-Dreyfus previously told Entertainment Weekly during an exclusive interview that Thunderbolts* will lay her entire secret plot bare. "You're going to see her entire plan unfold," she said. "It has a lot of mystery to it and there's some twists and turns that you don't see coming, which are the best kind. There's a lot of suspense, which is very groovy."

Thunderbolts* will open in theaters this May 2. Watch the new trailer above.
