|The following information is from the Adventure Time comic book series. It may not be part of the same canon or continuity as the animated series.|
ALN has a similar appearance to BMO with some slight differences. His screen is vertical as opposed to BMO's square screen. He has two drives at the right of his screen. On the side of his body is his name ALN with his arms at the bottom and speaker at the top of his side.
- Adventure Tim said ALN's name origin is not that awesome due to it being on his side.
- All of the letters in his name are just one letter before BMO's name (A=B,L=M,N=O). This is similar to the 1968 movie 2001:A Space Odyssey computer HAL 9000, whose acronym is often speculated to be taken from one letter before the company IBM.
- ALN's creator is possibly Al.
