Boron is the first high-ranking member of the Synvasion Force (I think that’s what I’m gonna be naming it from now on) Hydrogen will come across, and the one who kidnaps Helium in the beginning of Atomic Protocol! However, you don’t get to fight him until later on until the end of the arc. He will, however, make several appearances throughout the game, either kidnapping more elements or causing an event to happen in the background. Or just making a short-but-sweet cameo.
As thick-skulled as he may appear, Boron is actually the second-in-command of the force. He takes orders from no one other than the leader of the Synvasion, and follows them without question. As a matter of fact, no one has ever heard him speak at all! Included with a tremendous amount of strength at his disposal, he can also shrug off most incoming attacks with ease! On the bright side, however, he’s mostly a docile being. He never attacks unless ordered or provoked to. If you ask anyone in the Synvasion force what their biggest challenge is, they’d probably tell you it’s convincing Boron to make a different expression other than that blank stare he has plastered on his face.
