Allpress has survived various illnesses, including lung cancer over the years and it seems that no disease can kill him. However, he was diagnosed with Lou Gehrig's disease six months ago, which caused the death of neuron controlling voluntary muscles, and it was hard to beat, but according to his son, he fought to the end.
To most Power Rangers fans, he is best known for his role as Master Phant/Elephant Spirit Ranger in Power Rangers Jungle Fury. From all of us here, thank you for the memories.
