Wideload is the biggest and strongest of the Throttlebots; he can haul as much as one million pounds in his role as a materials transporter. But this supreme strength is no source of pride for Wideload: his work keeps him pretty filthy most of the time, and he's a consummate neat freak. Highly superficial, he prides himself on his appearance and judges others on theirs. His unusual susceptibility to rust is thus a source of embarrassment.
His alt-mode is a Caterpillar 777 Dump Truck.
