Today, I will talk to you about the three forms of Optimus Prime Super Mode, Fusion Mode Optimus Prime and Knight Mode. In Transformers 1 to 3, Optimus Prime's normal mode does not have the ability to fly, the car form is the Peterbilt 379 heavy-duty tractor truck, horsepower reaches 500 horses, the fastest speed is about 200 kilometers per hour, from 1987 production to 2007 discontinued, the subsequent replacement model is the Peterbilt 389.

Transformers 3, Optimus Prime's truck with a carriage, which contains all its equipment, in the 5 movies, the most used transformers are also Optimus Prime. The carriage also contains Optimus Prime's flying equipment, which can be understood as the Optimus Prime with equipment equivalent to Super Mode, sometimes referred to as the Omega Battle Suit. When flying Optimus Prime, the vest worn is very conspicuous, I think its flight ability in this mode is quite limited, first of all, there is not much external fuel, and the second speed is also very difficult to guarantee, so in this mode, Optimus Prime's flight speed may be similar to that of ordinary Decepticons hundreds of kilometers per hour, and it is impossible to reach several Mach.
Optimus Prime Omega form or ultimate Optimus Prime
Take another look at the Combination Mode of Transformers 2 Optimus Prime and Skyfire, which has appeared in many Transformers animations. Sending the energy from the Heavenly Fire Seed directly to Optimus Prime, Optimus Received the Vest Blessing of Heavenly Fire, and the Skyfire Suit was much stronger than the Omega Suit I think.
The first is the degree of solidity, I think this is more solid than Omega, and the second is in terms of flight ability, the flight speed of Skyfire ranks second among all individual Transformers, and with the blessing of sky fire engines, it will definitely be much stronger than the two small engines equipped by Optimus Prime itself.
The third is in terms of firepower and combat power, compared to the Omega suit is also a big upgrade, after all, this is two Transformers combined into one, there is a heavenly fire ability energy plus firepower, directly crushing the superior strength of the fallen King Kong. In the single Transformers, that is, not counting the Creator Gods and other Kongs such as the Primordial Heavenly Emperor Kuntasha, the fallen Kongs should be the strongest in combat. However, it was still crushed by the power of optimus prime, coupled with the power of the ancient transformers of heavenly fire.
This set was unloaded after use, I think it is a pity, if you can directly give Optimus Prime to use, then why change to Omega suit later, and Omega's vest is not as good as the Skyfire suit and Optimus Prime.
Why can the Knight Form Optimus Fly to the Universe and fly back to Cybertron, in Paramount's 5 movies, a single Transformer does not need a spaceship or space teleportation, and can fly directly from Cybertron to Earth or from Earth to Cybertron, there are currently only two, that is, Megatron and Optimus Prime.
Before said optimus prime flying kit belongs to the vest, according to the theory can not fly so far, there are small partners said that transformers 4 absorbed the forbidden tinder source, absorb the tinder source of this kind of thing, you have to believe that Optimus Prime will not do; and there is no clear let us see optimus prime to take the forbidden tinder, confinement does not have the ability to fly, are driving the spaceship around, then what is going on?
Why did Optimus Prime's flight ability get such a big upgrade. This has to start with Wei Zhentian, the fastest Transformer, and the sound waves flew from the moon to saturn's moon, which took 14 years one way. After Transformers 2 is activated by the fragments of the Tinder Source, in a full energy state, it can be quickly reached to saturn's moons in seconds, and its speed should have reached the state of the speed of light.
Why can Transformers 4 Optimus Fly, I think normally the answer should be revealed in the Fan wai, but there are very few Fan Wai works in 4 to 5, because transformers 6 are not planned. In Transformers 4, KSI conducted a very detailed study of Megatron, and even portrayed a shocking sky, combined with Transformers 1 through reverse research to obtain flight technology from Megatron, I think in Transformers 4, it is very likely that Optimus Prime absorbed Ksi's technology and copied The flying ability of Megatron. If anything, I think it might be written this way to fill the bug that Optimus Prime's flight speed has become the same as that of Wei Zhentian.
It really didn't take anything, just take a shield to resist the heat, and then take off directly to Cybertron, of course, it can't fly like this all the time, it doesn't have so much fuel, it sets navigation on the way, and then after being captured by the gravity of the planet, it follows the cosmic speed, and so slowly floats past.
