Silva is one of my favorite villains in sentai ! Call me crazy but I'm pretty sure is for something in the design of the T800 Terminator (the same way the Predator was said to be inspired by another sentai villain).
I'm just curious, for your Bio, Live, Kaku subs, are you guys using captions for your subs?
If not... here
Index of /subtitles/japanese
For Live: Index of /subtitles/japanese/Choujuu_Sentai_Liveman
might is be a little risqué of me to ask how little ol' Fiveman is doing?
