Transformers Armada (known as micron legend in Japan) is shown on air around 2002-2004. The gimmick of this series are the power enhancing transformers called Mini-Cons
I had a few collection from the series. This is the box packaging from Takara of Hot Shot.
The alternate mode of Hot shot is a sport car. It basically pay homage to G1 Hot Rod.
Jolt is a Mini-Cons that transforms into a red helicopter. Jolt had a gun which he shares with Hot Shot
Jolt's gun can be attached to Hot Shot in his vehicle mode. Jolt is partnered with Hot Shot and is capable of flying Hot Shot in this mode.
Jolt can fold down his rear half as helicopter to become a propeller to enable Hot Shot to travel short distance in air, achieve higher speed on land and travel underwater.
Hot Shot can hold up to a maximum of 4 Mini-Cons at a time in vehicle mode
Hot shot in robot mode. Without Jolt, he has no weapon at all. His personality and appearance resemble that of a young racing driver. In the series, Hot Shot was entrusted as the guardian for the Star Saber
Optimus Prime sees potential in Hot Shot to be a leader (which is more prominent in the sequel, Transformers Energon). Hot Shot also took command of the Autobot (as the matrix of leadership was passed to him by Optimus) for a short period when Optimus Prime was destroyed.
Jolt is required to release a cannon over his head. Jolt will release the rear wheel shaft which converts to a cannon. Hot Shot head visor can be lowered so he can take an accurate shot at his enemy.
Here are the transformation manual of both Hot Shot and Jolt by Takara. I find the instruction manual from Takara is more comprehensive than those by Hasbro.
