Transformers WreckGar

WreckGar started life as a Junkion allied with the Autobots. Then the Second Great War happened and like nearly all bots whether they were Autobots or Decepticons, his memory was almost entirely erased and all went black.

When he came to it was on Earth. As he transformed he was attacked by crazed creatures hell-bent on eating him. He escaped none the worse for wear and found himself roaming a hellish landscape that somehow felt familiar. He created a castle of junk where he watched over the red-stained planet.

Until the 'Noks arrived.
