"Edison" is taken from "Thomas Edison"
"T. Energison" is a combination of "Thomas Edison" and "Energy".
T. Energison is based on and named after Thomas Alva Edison, the man who patented the first commercially successful incandescent light-bulb. The phonograph, the lower half of his Yo-kai's body, is one of Edison's inventions.
When he is first summoned, a helper appears next to him, appears giving rope to his phonograph.
Curiously, he doesn't reappear any time more, not even when Edison's summon ends.
