Cob has fluffy hair. He is wearing fancy clothing and wearing a cape.
Several days after the exam's completion, Cob is enlisted into the Royal Knights for his Spatial Magic. He opens a doorway to the Gravito Rock Zone's floating dungeon, and Mereoleona Vermillion orders him to remain outside while the rest of the squad divides into teams and enters the base. Cob jams other Spatial Magic to impede Valtos and others from returning to the base.
After Patolli sets the last magic stone, Cob is possessed by the elf Ado. Later that night, all the remaining elves are exorcised after William Vangeance and Licht combine their magic to connect the elves to a giant tree through which Asta sends Anti Magic.
- Spatial Magic: Cob uses this rare magic attribute to manipulate space. He manifests a pair of large doors at both ends of his portals. Because he can transport large groups of people at once, Cob serves the Magic Emperor by moving the kingdom's armies.
- Grimoire: Cob possesses a three-leaf clover grimoire that contains various space-based magic spells.
- Cob ranked #71 in the second popularity poll.
- Portaport may be a reference to the French phrase porte-à-porte, which means "door-to-door".
