She-Hulk: Attorney At Law Episode 4 just revealed that there are more terrifying beings in the franchise that may originate from doves like the demon-like things that Donny Blaze summoned, but where are they from? The Marvel Cinematic Universe has introduced a lot of terrifying creatures from various places.
Donny Blaze, a third-grade magician, charlatan, and dropout from Kamar-Taj, has displeased the current Sorcerer Supreme, Wong, as he employs “magic” unlawfully through his tedious magic performances at a private theater and he might also result in some serious issues as a result.

He first sent Madisynn, a new acquaintance of Wong’s who nicknamed him “Wongers,” to a realm with a lava pit, where she was only spared by striking a contract with a talking goat she subsequently called “Jake” during the trial. Madisynn connected with Wong after donating six droplets of her blood to be shipped someplace else.
This made Donny Blaze come to Wong’s attention. Because he had some sorcerer training at Kamar-Taj and possesses a sling ring similar to Doctor Strange’s and Wong’s, he may portal into other worlds. However, his “magic” performances are fake and dull.
Unfortunately, in an effort to keep the audience alive, he called a dove that laid an egg, which broke apart to show a creature that resembled a demon and that, when struck, simply grew. When things get out of control, he contacts Wong. What a snub, but the Sorcerer Supreme will do everything to save the cosmos.
The infant creatures that resembled demons emerged from what appeared to be a dark dimension; it’s possible that this is the same dimension where Madisynn nearly fell into a lava pit. The multiverse of madness’s Hell’s gate, which was initially seen in Doctor Strange in the Multiverse of Madness, is eerily identical to the realm.

These demon-like creatures, who resembled bats and grew when they were hit, made their MCU debut in a swarm, and the realm in which they appeared in the series has not yet been identified. For all we know, this may be Hell’s entrance, and these might be the bat-like monsters that inhabit this place.
Anything is conceivable with the Multiverse Saga in the MCU, and when it opens up to yet-to-be-opened doors, the world from where these creatures originate may introduce another monster to the MCU, perhaps someone like Dormammu or something worse. Episode 4 of She-Hulk: Attorney At Law is currently available on Disney Plus.
