Say hello to Slagheap of Kaon!
A failed "imprint" clone of Grimlock, this mutant Autobot began life as a low level smeltery worker. Quiet, obedient, easily replaceable - a perfect experimental subject to overwrite with a copy of Grimlock's Point One Percenter spark.
The fragmented, howling monster that resulted was anything but.
