The Trinity: Explained using Vegapunk (from One Piece) as an analogy

Vegapunk is a scientist who ate a fruit that gives him a super-brain. Whenever he gains knowledge, his head/brain gets physically bigger. So, he put his brain on a "satellite". This satellite allows storage of a lot of information. And he put a receptor on his head. So, basically he has a remote brain.

Then he realized that there is so much that he needed to do, and he doesnt have time. So, he created 2 robots, and put receptors on their heads. These robots have personality expressions of their own. They are like different representations of Vegapunk.

All 3 had access to the brain satellite, so each one of them is fully Vegapunk, but also fully human or fully robot. The brain satellite represents the essence of Vegapunk.

Later on, the original Vegapunk dies (the one who created the robots). However, the other vegapunks didnt die. Because Vegapunk himself was basically the brain satellite.

Now imagine this... what if... all 3 had always existed and will exist eternally? What if the brain satellite had no physical form but exists as part of all 3 as a single essence which makes (links) them all as Vegapunk(God)? The essence itself would be the God, but it would fully be parts of all 3. What if instead of robots, one was a bird, one was human and one was a ghost?

One would be fully Vegapunk, and fully human. One would be fully Vegapunk, and fully bird. One would be fully Vegapunk, and fully ghost. But the bird wouldnt be the human or ghost. The human wouldnt be bird or ghost. The ghost wouldnt be bird or human.

Isn't that basically like the trinity? Are there any flaws here? Any more tweaks to be made?
