An entity from another dimension that has been drawn to the chaos of the Borderland. It doesn't understand the rules but is powerful enough to disrupt them, causing even more dangerous and unpredictable situations for the characters.
Perhaps a group of survivors who have become so desperate to get out of the Borderland that they are willing to sacrifice anyone. They could be the antagonists as they would clash with the main characters' more moral approach to survival.
Another option could be a corrupted version of Asriel. Maybe Alice's arrival somehow stirs up the darker parts of his past and he becomes a force against her, believing she is a threat to the delicate balance in the Underground.
Yes, Alice in Borderland is originally a manga.
It could be a new vampire who is jealous of Bella's relationship with the Cullens. This vampire might have some special power that allows them to manipulate memories, like Alice's memories of Bella. They see Bella as a threat to their own plans in the vampire world, so they try to create chaos by making Alice forget about her.
The Caterpillar could be the main antagonist. He has always been a bit of an enigma in Wonderland. Maybe as Alice shrinks, he sees her as a threat to his control over the small part of Wonderland he rules and tries to stop her from exploring further.
A jealous student could be the main antagonist. This student might have a crush on Alice and see Bella as a threat to their relationship. They could start spreading rumors about Bella, trying to make her look bad in front of Alice and the other students.
I think it's a mystery that's not revealed until later in the manga. You'll have to keep reading to find out!
