BackstoryHe was only a kid when his home planet blew up. But he grew up on a deserted forest on Earth. He matured over the time and became grumpy and tough. Before he was a kind soft calm fellow now he is the opposite.
Rammer is a hulking, broad-shouldered alien covered in natural armor plating on its back, shoulders, and the backs of his arms. This armor can withstand acids, lasers, and even a g-force drop from space without any harm to the subject. Rammr can roll into a ball like an armadillo or pillbug to encase itself in this plating. There is enough space within the shell while rolled up to protect and transport people or objects. When in the form of a rolled-up ball, Rammer can increase its rotational momentum and roll into enemies as an attack, as well as ricocheting himself off surfaces. It's plates are tough enough to be like car wheels when in a ball. However, it is subjected to the physical laws of reflection and conservation of momentum, meaning that it has difficulty stopping or controlling its direction if it picks up speed. By spinning in the same spot rapidly it can create a tornado like XLR8. Rammer's armored shell is used for a defensive mechanism, which means that it is extremely resilient. The shell is durable enough to survive a freefall from the upper limits of the Earth's atmosphere, including the heat of atmospheric re-entry, and still leave Rammer and anything held inside the ball intact, though the landing still creates some pain due to the large crater left there. Nothing has been known to penatrate the shell.
Rammer is subjected to the physical laws of reflection and conservation of momentum, meaning that he has difficulty stopping or controlling its direction if it picks up speed. Also, if Rammer is on a sticky enough surface, he can't get up.
