Keyuri likes small terrains like the Isometric Arena or any indoors arena since she has a huge advantage fighting opponents when separated by multiple floors.
Alan Chang Boy Genius loves huge open areas and cities since the more room SUPER ROBOT has, the better for him. His favorite terrain is Genius City of course.
Roman probably likes any area that's big enough to field an army. Ironically the Isometric Arena is pretty much terrible for her.
Lizard favors mid-sized or larger arenas where there are objects to use for stealth and plenty of room for him to make use of his mach 2 flight speed. Cities and his own home Terrain the Harvard Magic School are ideal for this I'd think.
