Here we have Brock vs his Croagunk in an interesting face off.
Brock is credited as the third major character in the anime, but has been criticized (rightly so) by fans for having no plot and no personality.
On the other hand, Croagunk has way more personality and had a rivalry with the Team Galactic Toxicroak.
Brock's recurring gag is hitting on every girl he sees, while Croagunk's gag is using Poison Jab and dragging his trainer off to an undisclosed location.
So discuss, who REALLY was the third major DP character? Brock? Or was it his Croagunk?
