Robert the Strong was a famous hero who battled against the Dragonkin in the Fourth Age during the Dragonkin Conflicts and forced them into hiding.
He is significantly taller than an ordinary human and appears to be wearing armour resembling rock-shell armour, and wields a unique bow which resembles an ogre bow.
During a cutscene, Robert is seen slaying one of the Dragonkin in their castle after it kills his pet panther, Odysseus. The quest also reveals that Bob the Cat is the reincarnation of Robert the Strong.
To help Bob the Cat remember his previous life as Robert the Strong, the player is tasked with defeating the latter after entering the cat's mind. His damage is only partially reduced by Protect from Missiles. The player can hide behind one of the four pillars in the boss area to mitigate the damage of his special attack.
He is then seen without his helmet during a cutscene. Here, it is revealed what Robert did with the key pieces the player is required to find.
- Robert the Strong's Strong Arrow special attack is a nod to Nomad's Soul Blast during Nomad's Requiem in RuneScape 3. His mannerisms also pay homage to Nomad.
- Robert the Strong may be a reference to Ser Robert Strong, a monstrous knight in George R.R. Martin's fantasy series A Song of Ice and Fire.
