A few glowing dots may be the biggest power-level hint yet. Marvel’s new “Silence Your Phones” promo for Avengers: Doomsday shows Doctor Doom unleashing his abilities with the Kirby Krackle effect, and that suggests Robert Downey Jr.’s villain is on another level.

What Is the Kirby Krackle?
The Kirby Krackle is the dotted energy effect created by Marvel legend Jack Kirby. His comics use it to show the strongest powers and characters in Marvel history. In the promo, it appears around Doom as he fights Chris Hemsworth’s Thor, shortly after he tells the heroes they have lived stolen lives.
A First for Live-Action Marvel
This is the first time the effect has appeared in a live-action MCU project. Until now, it has only shown up in animated shows, which makes the choice feel deliberate. Marvel seems to be giving Doom his most comic-accurate screen version yet, after the earlier Fantastic Four films of the 2000s and 2010s failed to do the character justice.

What the Russo Brothers Say
Directors Joe and Anthony Russo told Fandango that Doom’s magic is ancient and that he is both powerful and a genius who studies his foes. He steps onto a battlefield only with a tactical or power advantage, so he is very hard to beat. They also contrasted him with Thanos, whom they described as a brute force of nature, while Doom is more Machiavellian and manipulative.
Who Else Has Used the Effect in the MCU?
The Kirby Krackle has so far appeared in animated projects such as What If…? and Marvel Zombies. Here are some of the cosmic-level characters who have used it:
| Character | Show | Why They’re Powerful |
|---|---|---|
| Infinity Ultron | What If…? | Near-omniscient after taking the Infinity Stones |
| Strange Supreme | What If…? | Absorbed mystical powers, can shatter reality |
| Captain Carter | What If…? | Survived wielding all six Infinity Stones |
| Uatu the Watcher | What If…? | Knows all events, creates force fields |
| Storm, Goddess of Thunder | What If…? | Worthy of Mjolnir, cosmic-powered |
| Kahhori | What If…? | Powers drawn from the Space Stone |
| Arishem | What If…? | Celestial who battles a powered-up Agatha |
| Infinity Hulk | Marvel Zombies | Limitless energy from the Infinity Stones |
| Zombie Wanda | Marvel Zombies | Chaos Magic and reality-warping |
Why It Matters
Putting Doom in that company signals that he’s meant to be a threat unlike any the Avengers have faced. A recent post-credits scene in Avengers: Endgame Encore also showed him recruiting Bruce Banner, which suggests careful, calculated planning. Expect a villain who wins through strategy as well as raw power.
