|“Be free, Rodrigo! You've earned it.”|
|— Pythor to Rodrigo in "The Corridor of Elders"|
Rodrigo is a swamp rat that Pythor befriended and named during the Second Serpentine War. Ridden by the tiny Pythor, he helped him get to the battle of the Elemental Masters and the fake Anacondrai and was freed by him afterward.
After escaping Rodrigo and finding the spellbook, Pythor traveled on Rodrigo to the Corridor of Elders to tell Lloyd about a spell that can stop the Serpentine War. Afterwards, Pythor set him free.
- Pythor had also named his ball Rodrigo while in Kryptarium Prison, indicating he is fond of the name.
- A rat with the same appearance as Rodrigo appeared in "Public Enemy Number One."
