This line of thought had barely begun to be explored in depth before it ran into too many problems. First, no one knew what the Great Old Ones used to identify their summoners. What if they relied not on brainwaves, but on life force or something else? Then building a machine would definitely be useless.
Second, simulating human brainwaves was extremely difficult. Calling it simulating brainwaves would be an understatement—it would be more like directly creating a person, or conjuring an artificial human brain from nothing. Even by the technological standards of Helen's universe, such research would take years.
In the end, they simply did not know enough about the Great Old Ones. After discussing it for a long time and proposing all kinds of ideas, they were ultimately stumped by their inability to determine how the Great Old Ones responded to summons.
Since that was the case, they decided they needed a sample to study. Helen proposed summoning a Great Old One over and then letting her take a bite out of it.
Doomsday's innate Evolutionary Ability allowed her to analyze an enemy's powers after eating part of them and learn them to a certain extent. As long as Helen bit a Great Old One, she could more or less figure out what they were all about.
This was the most feasible method so far, and everyone present was the sort to take risks without blinking. After discussing the details, they really did intend to put it into practice.
The people present did have the skills to back up their boldness. Harley and Barry were temporarily unable to use this universe's energy, but they had both been good students at the magic academy and possessed solid Magic Theory knowledge, so they were responsible for preparing the summoning circle, inscribing
