Grimlock when into the junkyard in search of a new alternate mode. Grimlock was a triple changer, he needed an effective vehicle mode. He walked around the yard as he found it. A broken down, MAZ-543/7310 artillery truck, it was perfect for him as it had tons of firepower.
After the initial defeat of the army of minicons, Optimus, Soundwave, Shockwave, Windblade, Drift, Bumblebee, Strongarm, Sideswipe and Grimlock travelled up the highway towards a Decepticon signal.
They rode up as Bumblebee spoke to his team, "Were are taking a long time tracing our fugitive signal. If the Con knows anything the Decepticon Island, it must capture him. Get ready to go off-road."
Optimus drove alongside Bumblebee as he had opposed his point, "We can not risk going off-road as there are unforeseen driving hazards." Bumblebee counter his point, "I appreciate your input Optimus but as leader of the team, I think we make our own way. Also, know this part of the part of the earth better than you Optimus."
"However, bumblebee," Shockwave said with an annoyed tone, "Simply being the leader doesn't mean you know what is best and knowing the forest doesn't make it safer beside you have been here a week longer than Optimus."
