This is a 5″ Chogokin Jr Kurojishi figure from the anime Ninja Senshi Tobikage. That appears to be this yellow lion robot. After a little search I found this ninja robot anime. I have watched a little of the first episode Ninja Robots in English dubs by Cartoon Network in 1995 and Japanese version from 1985 – 1986 on Youtube, but it looks like they stream it on Anime Sols. It might be worth watching, though I usually like the Japanese version as they will not edit out the violence.
I liked the bigger DX robots Tobikage & Houraioh, but not this little all plastic ST version. It does not earn the Chogokin Jr name as there is no diecast metal in this robot. I was trying to get the other figures in the series but only ended up getting this little one. This one looks cheap and clunky. There was not a lot of thought put into the build for this. It is pretty much just a brick except for a little arm rotation. Probably one of those cheap train station toys to shut up the kids. The Kurojishi toy and box reminds me a lot of the Victora Albegas I have here. Sadly, I am afraid the thing I like most about this robot is the box.
Here is the opening for the anime tv show Ninja Senshi Tobikage from 1985-1986
