Porygon2 - With Eviolite, NEVER DIES, and TriAttack is one of my favorite moves
Blaziken because i usually struggle with getting 3 Physicals and 3 Specials (Usually end up with 4 specials). Also my teams usually don't end up with a Fighting Type
Milotic's design has always been one of my favorites, and probably the best nonlegendary Water type IMO (because it never dies)
Roserade will count for my favorite Grass type and Poison type. Like the design + Toxic Spikes followed up by a Gengar's Hex kills so many things in 1hit.
Pachirisu since im not really a fan of Electric types in general. I wish there was a fangame that focuses on Doubles (or an Option in Reborn/other fangames i enjoy) so i could use him to his full potential.
Garchomp as my favorite Dragon and Ground type since im not a fan of Ground types. Any game where i have the choice to get, I GET HIM. He's also my favorite Pokemon overall.
Metagross is on pretty much all of my teams because he's so solid, and his Shiny is amazing
Talonflame as favorite Flying, because glass-cannons are fun
Spiritomb as favorite Ghost because his design is absolutely amazing.
Umbreon as favorite Dark type because cool design and synergy in his moveset
Lucario is about the only Fighting type i use. Cool design
Togekiss used to be my favorite Flying type until Talonflame came along. PermaFlinch is also pretty fun.
Lapras for favorite Ice type. Not much of a fan of the other ice types, and i love his Hydration-RainDance-Rest set since you can stack your EVs and nature to turn him into quite a tank.
Gothitelle as favorite Psychic because Shadow Tag. Can also make Gothitelle quite the tank
Volcarona as favorite bug since he's about the only one i will (somewhat) willingly use.
