Hatter

Hatter is a character in the Avengers Grimm series, played by Randall Yarbrough. He appears in Avengers Grimm: Time Wars and Sinister Squad. He is based on the Hatter from Alice's Adventures in Wonderland by Lewis Carroll.

Sinister Squad
Hatter often speaks over the intercom at Looking Glass. When Death's Messengers are infiltrating the building, Alice requests Goldilocks and the others go fetch Hatter for his help. He is distracted by the dance music he is listening to, but eventually realizes an attack is going on and attacks one of the messengers with a tea kettle.

Alice then gives him a psychedelic drug to help him take a mental trip to the Underworld to learn more about Death's plans. This helps reveal that Death is more interested in Rumpelstiltskin than Alice was told by him.

In the final fight, Hatter is still high but briefly tries to help by hitting a Messenger with his hat.

Time Wars
Hatter now seems to serve as Alice's right-hand man at Looking Glass. He assists her in her plans to stop Magda the Mad by utilizing technology and making drugs. At the end of the film, he officiates the wedding of Snow White and Charles.

In the potential future where Magda marries Charles, Hatter has died.

Personality
Hatter likes riddles and is fond of hallucinogenic drugs, even seeming to put some in his tea. He seems to become easily distracted from his work, as Alice needed other people to go find him when his help was required to stop Death.

Hatter is well-versed enough in chemistry to make medicine and drugs for himself and Alice. He is generally more soft-spoken and gentle than the other characters.
