Maxie is the leader of Team Magma in the games Ruby, Emerald & Omega Ruby, and honestly, he is the better Hoenn evil team leader, as his character design is a bit more evil compared to design of Archie, and I feel just how he acts is a bit more villainous compared to how Archie acts. When it comes to battles though, that's where Maxie doesn't shine as much, as his main ace can easily be handled by a water type move. The first battle against Maxie in Ruby & Omega Ruby has him using Mightyena, Golbat & Camerupt, while first battle in Emerald he uses Mightyena, Zubat & Camerupt. The second battle Maxie uses team of Mightyena, Crobat & Camerupt in Ruby & Emerald, while he uses Mightyena, Weezing, Crobat & Mega Camerupt in Omega Ruby second Maxie battle. There is also a double battle against Maxie & a magma grunt in Emerald where he also uses team of Mightyena, Crobat & Camerupt. Maxie can also be found in the Omega Ruby Battle Maison multi battles where he'll use Mega Camerupt & Crobat, as well as the USUM Rainbow Rocket post game where he'll use Mightyena, Crobat, Weezing, Camerupt & Groudon. Overall, Maxie is a really great villain, and that's what made him stood out more than others I talked about, but just lack of challenge towards battling Maxie is what made me rank him for fifth over the other leaders that remain.
