Dreadbot
From MediaWiki
Dredbot draws a similar resemblance to The Dreads. He transforms into a weathered Volkswagon Type-2 bus. Dreadbot has a distinct cybertronian weapon, notorious for effectively obliterating his victims. He has a large frame, which makes him invulnerable to any type of ammunition, as well as being able to break through walls with ease.
In the past, Dreabot invaded a bank, killing nine humans. He is now kept in custody, courtesy possibly of the Transformers Reaction Force. [1]
