Drawn to Life: Two Realms introduces many new characters to the series, including a few Raposa, almost every Human, and a wide variety of Toys. However, there are also new enemy-esque characters in Rapoville at night, completely new to the Drawn to Life Series. Unfortunately, none of these characters play a role in the main story.
The Carrier Robot can be found in the Lavasteam District and is a Grey Baki riding in a robot. All the dialogue from the Carrier Robot seems to come from the robot itself.
Cumulus is another pair of entities, this time being a bird and a sentient cloud. All the dialogue from Cumulus comes from the bird, not the cloud. It was not in the base game and was added in the Creative Pack #2.
Dandyshroom is a sentient mushroom person with a dapper attire that can be found in the Watersong District.
Kuragekko is a jellyfish-esque entity that can be found near the Beach. It was not in the base game and was added in the Creative Pack #2.
Seedlee might be a Seedling, though they do have some notable differences. Seedlee can be found near the Banya Farm and was added to the game in the first Creative Pack.
Shork is a anthropomorphic shark that appears near the Beach. It appears to have a taste for Raposa, but doesn't eat any during the game.
Taz is a hedgehog-like character that can only speak in barks and growls. It was added to the game in the first Creative Pack.
Despite the unique appearance of each of these characters, not a single one is anything more than a background character.
