>>31905162He's a scientist that doesn't fit into the "muh good/bad character"; he's in for the sole purpose of making science, sides be damned, hence him working for Team Plasma even though he disagreed with their way to approach power. He never cared about "let's dominate the world!" or "let's save the world from the bad guys!", all that mattered is the inner potential within Pokemon and to bring it out through scientific ways, even if it means destroying the world as he mentioned in BW2.
His theme and team were boss too.
