My latest 'retrofire' figure is the White Tiger Megazord (or Won Tiger, if you prefer).
This figure was made from a 6 inch Tiger zord figure (from a special sized Tor set), an SD gundam, a 3 3/4 inch gundam, and hands from a Transformers Alternators Sunstreaker.
The figure stands at about 6" tall and has a total of 24 points of articulation. It also features a removable 'lightning attack' and an energy piece that fits onto the sword.
The Tiger Megazord fits in pretty well with other figures in the Retrofire line but is a little short compared to SRCs.
