>>49088607here's how they got registered into hall of fame, mind you at least three of them leveled up after the battle iirc (Barrow did for sure).
Terra and Radia are main battlers but their coverage was mediocre; Earthquake Razorleaf Giga Drain and Bite, and Discharge Thunderwave Thunderbolt Bite respectively.
Horrible is secondary battler with Brick Break (almost useless), Surf, Psychic, and Ice Beam. Mark is mostly for catching and thiefing but can battle too, three of his move slots are Thief, False Swipe, and Thunder Wave (i slapped Flamethrower in slot four because Radia couldn't learn it iirc).
Scourge didn't get used, is catching only for those cases where False Swipe aint gonna work (e.g. ghosts) or target is Electric or Ground type and immune to Thunder Wave; has two super low-power dmg moves (Absorb power 20, Poison something power 15) and Stun Spore, and Sweet Scent (for field use).
Barrow was honestly just along for the ride, I rotate whoever's in the last slot constantly to evolve mons for dex completion n shit but if I had to pick one mon to be somewhat used it would be Barrow.
