Erekin

Elekiter-type Time Shifter with power over electricity. Elekin-Con can attack with electric shocks. Elekin-Master is bigger than his normal self (save for the addition of two arms and two legs like a real human) which looks like and pays tribute to giant robots like Voltes V and Daimos. He was found in Edo-era Japan with Hiraga Gennai.
