Slender Mech is a mystery. He looks like a Transformer, but doesn’t act like one. It is uncertain if he is a social creature, understands Cybertronian languages or behaviors, or even why Transformers appear to be his primary targets. It sometimes seems as if he is capable of possessing his targets in some cases. Slender Mech's mere appearance provokes fear. This is partially due to his towering height and overall unnerving appearance, and partially due to his behavior, which is almost completely alien. Transformers also find it extremely hard to describe The Slender Mech: a description in words can be given, but often lack the ability the fully describe the creature. It is believed that Slender Mech is from/exists on a fourth dimensional plane, which would account for some of his apparent abilities.
