So I made this topic to tell you what(I think)team/pokemon we will have to fight in the E4.
We all know who are the E4 members :
So now we will try to guess their teams :
First,Benett&Laura has to be a double battle a 6vs12 like in the glass gauntlet. The field has to be the flowergarden field which we have never seen but we know it increases both Laura's and Benett mons because Grass gets 1.5 and Swarm gets triggered in this field. Their teams are going to be Sun based : Chlorophyll Liligent and Quiver Dance Volcarona as their aces. Benett's team must have changed so no more butterflies and top-tier bugs like M-Beedrill or M-Pinsir,Scizor,Heracross,Leavanny with Chlorophyll. Laura's is a Grass specialist so maybe Venusaur or Victreebel and Cherrim but the E4 are based on more than 1 types so maybe Fire to goes with the Sun with Ninetails,Infernape,Delphox or even Blaziken (let's not mega).
Second,we have Heather who is a Flying type user and will fight most certainly in the Mountain Field in Solo because it's the place that fits her the most (Beryl Cemetary,near her home).She must have an HO team because of her personnality: M-Salamence for obvious reasons,Aerodactyl and Archeops because of the Rock boost,Shelly's Yanmega and Corey's Crobat and the last can be a Noivern or a Dragonite because I'm sure she will get along with Saphira (Pink haired and Sirius was the enemy of both's family).
Third, Elias it's logical that we will fight him in the Holy Field in Solo where Normal,Psychic and Dragon types are boosted. His ace will be Snorlax or Smeargle.His team should be composed of an Espeon(opposite of Luna), a Chatot(Taka), a Garchomp (his master Solaris) maybe Gallame and an Alakazam one of them being the Mega of his team.
Last but not least Anna. The Starlight Field is the best field for her Psychic,Dark and Fairy types are buffed here. Her ace should be Gothitelle ( especially the one from Beryl Library).Her Team could be composed of Clefable (Noel),Gardevoir(Her dad),Metagross,Starmie and Jirachi ( we all know it's not just a plush). I would rather think that she fights in Double like her Dad contrary to her bro.
Now that I told you my opinion it's U-Turn.
