This is an original mobile suit modified from the RGZ95 ReZEL.
The ReZEL is said to be a ZII-type MS, but I created this while fantasizing about an MS that fills the gap between the ZII and the ReZEL. When I read the ReZEL Wiki, I found out that the design was called "ZIII (Zee Try)", so I took that name and named it "RGZ-95β (Beta) Prototype ReZEL ZIII (Zee Try)".
I aimed for an MS that was both ZII-like and ReZEL-like.
Using the standard HGUC ReZEL as a base, I reused parts from the HGUC Zeta Gundam and painted it in low-visibility.
