The King of Braves GaoGaiGar
Both Jetfire and Jetstorm are the youngest members of the Elite Guard of all time. Both Jetfire and Jetstorm speak with Russian accents. Apparently they are Sentinel Prime's soldiers, obeying his every command. The twins' merging into Safeguard is similar to ChoRyuJin of "The King of Braves GaoGaiGar".
