Erol

He was a commander of the Krimzon Guard in Haven City serving under Baron Praxis and a Grand Champion of Haven City's racing circuit.

leading some Krimzon Guards to arrest Jak after his arrival in Haven City with Daxter. Daxter escaped, but Erol commanded the Krimzon Guard to "forget the rat." Erol and Baron Praxis subjected Jak to dark eco treatments for two years as part of a Dark Warrior program to fight the Metal Heads. When Daxter broke him free, Jak was itching for revenge on Praxis and Erol.

Erol is an egotistical sadist who takes pleasure out of other people's suffering, and enjoys a healthy life as Praxis' right hand man, not caring what he has to do to keep it. He is the parallel to Torn, who once held Erol's position but gave it up and became an outlaw as he could not stand to enforce the baron's laws. Erol has a fiery temper, making him quick to anger, and he does not tolerate losing. He enjoys fighting, as is shown in his eagerness to lead a troop on a full scale attack on the Metal Head nest, despite constant warnings that he would not stand a chance. This attitude was eventually his downfall, as he was blinded by his rage at Jak beating him and drove into a pile of Dark Eco as a result. As Cyber Errol he retained these basic traits, only all of them where now increased by his new found power. Again, his arrogance and hunger for strength brought him down. On the other hand, there is large a possibility of Erol having a softer side, that might have only been shown to Keira, assuming she is the "mechanic girl" the Baron mentions when scolding Erol for wasting time flirting.
