After solving the puzzles on the same side of the Borg Cube as the AllSpark, solvers are presented with the following answers (in alphabetical order):

• `AUSTERE TYPEFACE`
• `COLOR MICROGRAPHY`
• `GERI HALLIWELL`
• `LABORATORY TECHNOLOGISTS`
• `MISFIT MATHEMATICIANS`
• `RECREATIONAL USE`

Each word of the answers is a unique length which corresponds to one of the initial words of the given blank transformation chains. Next, solvers must determine the mechanics of transformation, which can be determined by studying the example steps:

• Red: Delete the letter
• Green: Double the letter
• Yellow: Replace the letter with a single bit flip in its 5-bit binary representation

The important yellow transform is confirmed by flavor about “electronic gymnastics” (which in retrospect, is “bit flips”). The word “Enable” is capitalized in flavor, indicating that words must come from the Enhanced North American Benchmark LExicon (ENABLE) wordlist.

However, even using ENABLE to constrain possible transformation steps, there are several options for each chain. The key realization, as specified in the flavor, is that the final configuration is a car model (which is also a word in ENABLE). With this constraint, the chains all have unique solutions:

Reading the first letters of the car models in the given order spells out what can defeat Megatron, namely (Optimus) `PRIME FACTORS`.
