Grief: (Sonic Boom version)

Grief was a troublemaker who grew up on the wrong side of town. As a younger child Grief was often in trouble with the law and was known to commit several misdemeanors while under the influence of his fellow groupies within several in school cliques. Yet Grief was often picked on because of his short stature compared to other Mobian kids of his size. Grief would often try to act tougher than he was and get beaten up for it. He would go home to his bed and cry due to him feeling weak.

However one day changed when Grief decided to run out of town from his parents and his mean hearted sister. Grief stumbled upon what appeared to be an aircraft wreck in the field. Grief not knowing any better started to investigate and found a dying alien inside called Gluube. Grief was able to help the alien out of a pile of wreckage. Sadly however Gluube was close to dying. Grief tried his hardest to keep the alien alive by bringing food and water to him but it was to no avail, however Gluube was thankful for the child's generosity and thought that he would be good to carry the DNA of his people so that his own genetics would survive and perhaps breed more of his kind in the form of more genetically diverse and healthy hybrids. Gluube was able to hook Grief up to a devise with the promise of fulfilling Grief's desires. Soon the devise forcefully have Grief an harmless and in fact beneficial version of cancer. Sadly it also was too much force for the alien to handle and killed him.
