Tyrwas
From Teletraan I: The Transformers Wiki
Tyrwas is the name of a god of the sky worshipped by pagan hippies Satan worshippers destined to burn in hell wizards in ancient Britain on the planet Earth, such as Beorht.
Leaving aside control of thunder, lightning, rain, and clouds, Tyrwas also appears to be responsible for recharging metal knights who, in 543 A.D., lack a suitable power socket into which they can plug themselves. A Decepticon Raider in King Arthur's Court
