So who has seen/is watching this? For those who don't know, it's an old mecha series that originally started in 1972 with Mazinger Z. After 90 or so episodes, they started a series based off the second mech that appeared at the end of M.Z, called Great Mazinger. After that, we have Grendizer. After that, we have the 6 (or 7) Episode OVA called Mazinkaiser. Currently watching Mazinger Z, and it is amazing.
