The Transporter is a class unique to Merlinus, from Fire Emblem: Binding Blade and Fire Emblem: Rekka no Ken. Basically, all a transporter does is to manage your items during battle. For example, if you gain an item from a village but if that particular character's inventory is full, the item can be sent to Merlinus if he is in the battle. In Binding Blade, Merlinus automatically starts out as a wagon. He can only gain a level by surviving 100 hits. In Rekka no Ken, however, he starts out as a Transporter (Tent). He gain levels in this way:
- He joins a battle.
- He automatically gains a level after clearing that battle.
When he reaches level 20 in Rekka no Ken, he will promote. He will then get a Wagon upon promotion.
