Veloci slash

On the scorching surface of Velocitron, dust swirls dance between the skeletons of abandoned tracks. Bumblebee is the first to notice an anomaly on the scanner - a pulsing signal from beneath the planet's rusty crust.
A group of Autobots break open an ancient hatch. Below are crystalline reservoirs of Synthetic Energon, emitting a dazzling blue glow. "This is enough to turn the tide of the war," whispers Bumblebee.
But on the crest of the crater is a silhouette. Veloci-Slash freezes, its optics greedily capturing the energy spectrum. The engine roars involuntarily. It was not Megatron's order that brought it here - but the pure instinct of a predator that sensed the fuel that could make it the fastest in the universe.
"This is mine," he hisses, activating the boosters. Below, the Autobots are unaware that the race has already begun.

He is an energon hunter.
