the Driver Transmétal is a arctefact series Animutants , held at the beginning by Mégatron in season 3. This one uses it then to create of Vélociraptor cyborgs intended to exterminate the human ones. It will cease building some when the maximals find the weak point of the creatures (their control center).

After that, Mégatron re-uses the driver on a maximum protoform, and a clone Transmétal 2 of maximum late the Dinobot (" makes use of it to create; Feral Scream"). Vélocitor seizes the arctefact then and gives it to Deathcharge, but is absorbed itself in the machine by accident, which also transforms it then him into transmétal 2. On its side, Deathcharge analyzes the maximum object at the base, then throws it in the lava, but the Black Widow catches up with it discreetly and tries to even use it on it. After some adventures, it is in its turn changed into transmétal 2. Thereafter, it is not any more question of this object in the series and one is unaware of what it became.
