Alina and the old witch
Mark didn't expect to see this. It was already overwhelming enough for him to realize the potential of replicating the intelligence cores. But, this news was even top of it.
What makes an Android different from a battle robot? Of course, the appearance makes a huge difference, but it is the presence of the core in the Android that makes it more special.
The intelligence core not only houses the Android's consciousness but also has unique abilities based on how it was created. That's why Alina, Allen, and Ark had different abilities in the first place. The system created them based on what it thought their abilities suited its host the most.
But, since Ark Prime was created by Mark, who used his own ether energy as the medium, the artificial intelligence Ark's intention here is to maximize the output. So, it went on extracting the best variant element it could do, from its ether particles and supplied it to the core, giving it space-based elements.
