Fang of the Sun Dougram was an anime TV series in the 80’s (1981 to 1983) and a full length film summarizing the series.
It was one of the first successors of the Mobile Suit Gundam series, depicting also giant robotic combat armor.
Originally in the 80’s Takara released a line of scale models as well as other diecast or toy merchandise, for what it worth it, the line comprised a well bunch on 1/72 scale models. Later this same models were repacked by Revell in the U.S. under the confusing name of Robotech Defenders. Original Takara kits was good quality, poseable and a challenge enough for modellers.
In more recent times, Max Factory is releasing a new line of Dougrams in 1/72 scale, depicting a very good quality kits than may be a pleasure to build for any fan. Max Factory still haven’t new tooled all the original kits Takara made in the time but most of them. Some of the 1/72 kits were also released by Doyusha, who mostly was doing the 1/144 line.
