Transformers were advanced silicon-based lifeforms from outer space. They were enormous, immensely powerful, and equipped with all manner of devastating firearms and high-tech energy weapons, possessing combat power that ordinary humans simply could not contend with!
At the beginning of the film Transformers 1, a single Decepticon wiped out an entire US Army base in an explosive display.
While that was partly because humanity had been completely unprepared for the Transformers' attack, it was still enough to demonstrate the Transformers' formidable combat capabilities!
They were exactly the opponents Chen Mo was looking for!
In terms of individual combat power, these Transformers were not much weaker than Hulk. They could make Chen Mo take the fight seriously, making them excellent sparring partners.
Besides luring the Decepticons to his doorstep for practice, Chen Mo had other considerations as well.
Like the Avengers world, the Transformers world was made up of multiple films. Aside from the AllSpark, which could transform mechanical objects into Transformers, many powerful things would appear in the future Transformers world.
The Matrix of Leadership, which contained immense energy and could revive dead Transformers; the Space Bridge, which could teleport incomparably massive planets through space; and the technology later developed by human scientists to artificially create Transformers from Transformer wreckage—all of these held considerable appeal for Chen Mo.
So Chen Mo did not intend to simply grab what he wanted and leave as he had in the Venom world!
Of course, Chen Mo also had no plans to build this world into one of his bases like the Avengers world. That would consume far too much time and energy.
Having the Avengers world as his base world was already enough. With powerful HYDRA, S.H.I.E.L.D., and Wakanda under his control, along with top scientific geniuses like Tony Stark and Princess Shuri
