The match between the Fey Fianna and the Oclis Zemo could be seen as a struggle between two different weapon philosophies.
The Oclis Zemo clearly sought to lead a resurgence in the use of ballistic weapons in the Hyper Generation. The striker mech did so in the most visually stimulating fashion possible by continually firing twin streams of impactful earth bullets from its rotary cannons.
There was no way that the machine could sustain this excessive rate of fire, but it did not have to! So long as it was able to take down a single opponent, its mission would be complete!
This was why the striker mech did everything possible to demolish its opponent as quickly as possible. It did not hesitate to rotate its heavy guns faster in order to spit out its bullets at a faster rate.
