form Two is when the MCU startedfielding criticisms of a “ villain problem,”claiming that the rounded , flesh - out hero are not complemented by rounded , build - out antagonists . Still , Phase Two had a duo of pretty great villains amid the generic , forgettable ace .

Trevor Slattery

Boy , this one really feel like a slap in the face . The Mandarin is Tony Stark ’s implike - bane in the strip   — the Joker to his Batman   — and the marketing forIron Man 3really got fan sleep with up for Ben Kingsley ’s take on the iconic character .

And then , he was divulge to be a beer - swilling association football ruffian who was simply take by Aldrich Killian to depict the Mandarin . What a letdown . Fortunately , Tony Leung ’s casting as the real Mandarinin theShang - Chimovie looks to fix that .

Malekith

Thor : The Dark Worldis often prognosticate the MCU ’s worst picture show , so it ’s unsurprising that its opposer Malekith exemplifies the worst kind of MCU scoundrel : a one - bill fibre with a vague malefic plan who speaks exclusively in neat , laggard - well-disposed soundbites .

Christopher Eccleston wasmassively wasted in the office , and has even spoken out against the movie in the eld since it was unloose .

Aldrich Killian

Shane Black originally need to make Rebecca Hall ’s lineament the primary baddie ofIron Man 3 , butthen - Marvel chief Ike Perlmutter nixed the idea , forcing Black to make Aldrich Killian the villain .

These enforced rewrites moderate to major plot holes , as it ’s clear that the first act is setting up Hall as the villain , and on top of that , Killian never feels like he poses a single ounce of a terror .

Yellowjacket

Ruthless business types are one of the MCU ’s favourite caudex baddie . A meridian example of this isAnt - Man ’s Darren Cross , the smarmy businessman who squeezed Hank Pym out of his fellowship and want to weaponize his shrinking tech .

Cross serves only to set upAnt - Manas a heist movie , as Pym recruits Scott Lang to steal the technical school . Corey Stoll is waste in the antagonist theatrical role .

Thanos

Thanos would go on to become one of the MCU ’s best villain   — mayhap the very good — when he took center point in the third and fourthAvengersmovies in Phase Three .

However , in his abbreviated appearances inGuardians of the Galaxy , which only served to establish his purpose for those late movies , he exemplified a major problem with the MCU ’s model : setting up future installments at the expensive of single motion picture .

Crossbones

Frank Grillo may have been a little short - changed by theCaptain Americasolo trilogy , as he ’s set up as Crossbones inThe Winter Soldierand then blown up in the opening move aspect ofCivil War , but he had some great scene in the former movie .

From the elevator fight with Cap to his third - bit engagement with the Falcon , the S.H.I.E.L.D. operative who knew he was work for Hydra all along appeared in some terrific action picture .

Ronan

InGuardians of the Galaxy , Ronan is an all - powerful warlord who want to adopt the Power Stone to destruct Xandar , which Thanos ended up doing a couple of movies later anyway . Ronan ’s scenes are actually pretty boring . When he ’s on - screen , the audience is justwaiting for the Guardians to derive back .

At the very least , Ronan ’s seriousness and self - importance dividing line hilariously with Peter Quill ’s brazen mockery . Lee Pace ’s reactionwhen Quill proposes a dance - offis priceless .

Ultron

Ultron is too big for his own goodness . He peril to wipe out humanity to save Earth from its own inhabitants . That programme is far too terrific to track in a unmarried movie . Plus , it ’s impossible for a character with the immense , global power of Ultron to be relatable .

James Spader make do to scavenge the character reference a little with his creepy-crawly outspoken public presentation . He made Ultron ’s scenes entertaining , even if the movie as a whole does n’t really control up .

Alexander Pierce

The Russo brother ’ direction ofCaptain America : The Winter Soldierwas intemperately work by the paranoid political thrillers of the ‘ 70s . In the post - Watergate epoch , picture show about administration conspiracies were rearing , and the hero at the nerve center of it all was usually played by Robert Redford .

So it was a stroke of upchuck mastermind to rent Redford to play the S.H.I.E.L.D. bureaucrat creditworthy forThe Winter Soldier ’s shameful conspiracy that Hydra ’s been run things for 70 years .

Nebula

Although they eventually became allies in the sequel , Nebula was an opposition of Gamora ’s in the firstGuardians of the Galaxymovie . She was compulsive to kill Gamora , just to prove to their adoptive don Thanos that she could .

Under the quarter round of both Thanos and Ronan , Nebula became blind by that desire . When she thought she ’d actually done it , after bollocks up her baby out into infinite , her remorse was palpable .
