I wouldn't say more dangerous. Ahui seems a bit more malicious and willing to act evil or do harm than OG Starlight, who was on a crazy egoistic power trip. And Garble's a straight bully. [/bq]
But who made more damage? a single guardian or someone who broke the timeline 7 times just for revenge?
It's like comparing Screwball with Magneto, okay, Screwball is a bad person but she just made tricks for fame and likes, nothing serious like Magneto who despiste he wants to keep the mutans save, makes a genocide.
It's impossible not making Glimmer less evil than Ahui.
