Ramhorn is one bad-tempered tape from the Transformers series. He is part of the mini-cassette Autobot team and takes on the form of a rhinoceros.
Ramhorn's bio painted him as extremely unruly and bad-tempered, prone to destroying anyone who violates his territory. His charge is formidable enough to knock a train off its tracks or upend an 18-wheeler with one blow.
As a member of the Autobot communications sub-group Ramhorn frequently worked with its other members - Blaster, Eject, Rewind and Steeljaw.
