17 years after Ed Nortonโs Hulk debuted in the MCU, the franchise is basically full of Hulks. The not-so classic Banner-Hulk remains active (and will return for Avengers: Doomsday), but now weโve also met She-Hulk, Tim Rothโs Abomination and of course Thunderbolt Ross made his bow as Red Hulk in Captain America: Brave New World. And thatโs not to mention Bannerโs Son Skaar, the weird variants introduced in What Ifโฆ? or the embarrassment of incel She-Hulk villain HulkKing.ย

An yet, for all the gamma-powered muscle walking around the MCU these days, we still donโt really have the Hulk anymore. At least, not the version Marvel fans once knew and loved. Somewhere between Avengers: Age of Ultron and Endgame, Marvel decided the most interesting thing about Bruce Banner was figuring out how to stop being the Hulk altogether. Thatโs how we ended up with โSmart Hulk,โ a solution to a character problem that never should have been solved.
And while Hulkโs solution was useful for Endgame, it also quite pointedly closed the book on one of the MCUโs most interesting character arcs. The conflict between man and monster, between vulnerability and rage, between wanting to be left alone and a burning need to protect and belongโฆ it was all why Hulk was one of the best original Avengers. And now that Banner is now seemingly content as a gentle giant genius, the MCU has a story vacuum where that irresistibly entertaining conflict used to be.
And thatโs exactly why Thunderbolts* was such an important release for MCU fans who like their struggle to be personified. Because, when you think about it, Lewis Pullmanโs Sentry is basically the perfect replacement for the original Hulkโs character arc.
Sentry Is The Secret Hulk Replacement Youโve Been Waiting For

On paper, Sentry is Superman with serious mental health issues: a man granted the power of โa million exploding sunsโ whose very existence is a paradox. Heโs a god-level superhero in the soft outer casing of an emotionally unstable, tormented, and perpetually terrified human. And then, of course, thereโs The Void – the dark, corrupting heart of Bobโs psyche that manifests as an apocalyptic, unstoppable force of destruction every time he loses control. That conflict of vulnerability and monstrous dark power sounds awfully familiar doesnโt it?
There is, of course, a chance that Bruce Bannerโs savage side returns in the future of the MCU, and we get to see more of the conflict between his urge for calm, and the bubbling rage bursting out of him, all green and violent. But if that doesnโt happen, Sentry might be exactly what youโve been waiting for. Bobโs arc, in fact, may even go further than Hulkโs ever did. Because Bobโs personality makes the deadly tug of war with the Void all the more poignant. Both characters are cursed by their split existence, but Bob is both a lot nicer and a lot more personally linked to his fellow heroes already.
And of course, Hulk was always still a hero, and the promise that heโd ever go bad was only ever dangled above us as an audience. Weโre haunted by the idea of Savage Hulk after seeing a glimpse of him in Age Of Ultron. That was never enough, and even though Hulk was always monstrous, his emotions and his desire to belong despite fear of himself still feels impressively sympathetic. Far more sympathetic, in fact, than a jolly green dork. Weโre confronted with the strange idea that in seeking humanity, Banner actually became more alien.
Though the end of Thunderbolts* suggests Bob has things under control, the threat of The Voidโs reappearance is part and parcel of who he is. And that internal war, wrapped in a man who could vaporize entire cities on a bad day, is everything the current MCU has been missing since Hulk got all homely andโฆ safe. Excitingly, Sentry isnโt just Hulk 2.0 (or whatever iteration weโre onto now), heโs a horrific upgrade. And hopefully, his popularity might remind us all – and Marvel – why the real Hulk mattered so much.
