So far in general Team Meteor seems to me to be a smarter and better written Team Galactic expy when it comes to their goals but also with added goal to become gods themselves while remaking the world, and so as long as they stay in Team Meator none of the grunts or members will get any sympathy from me.
As for individual members,
Solaris: So far he seems to be the most ruthless and evil team member and if not the leader seems to be the dragon, kinda fitting since he uses dragon pokemon. Needs to die in a fire.
ZEL: At first I thought xe had split personalty disorder but the more I interact with them the more I get the feeling that its more complicated and darker than that.
Lin: Haven't met her yet.
El: Haven't met him yet either but from what I read he seems to be a crazy cultist, however he was healed by Arceus and apparently wants to serve him. So I don't really know why he is in Team Meteor. He is probably the only redeemable character besides Taka.
Taka: Taka is nice, seems to not even agree with Team Meteor methods or motives and saved me from a trap. He appears to only be in Team Meteor out of loyalty for his father and hopefully is redeemable.
Blake: Haven't met him yet.
Fern: Started as a jerk type of rival only to get worse and worse as the game goes on. While it was a nice twist that he actually stays a jerk and becomes evil unlike Silver and Blue, he isn't a love to hate type of character and just gets on my nerves. If he steps up his villainy even more he'll need to join Solaris in dieing in a fire.
Corey: Was selfish and gave into both despair and Team Meteor when he had daughter to look afterward but his suicide complicates matters and did not deserve the awfull comments from Fern and the Lapis Ward citizens.
