If your opponent controls a monster: Target 1 of your "S-Force" monsters that is banished or in your GY; Special Summon it to your field in the same column as an opponent's monster. You can banish this card from your GY, then target 1 "S-Force" monster you control; move that target to another of your Main Monster Zones. You can only use 1 "S-Force Specimen" effect per turn, and only once that turn.
