Transformers Animated Jetfire and Jetstorm.
While Jetfire has flame abilities, Jetstorm has freeze and wind abilities.
Both jets combine.
The twins combine to form Safeguard.
Personally, I feel like this two pack is a blantant rip-off of the Gaogaigar twins Horyu and Enryu, the combined form, Safeguard, a rip-off of Choryujin. Sadly this set isn’t as impressive and the designs are not that great and feel somewhat forced. Even at sale price I feel like I overpaid for this set.
