Tito Flores is a drug dealer and the kingpin of one of the biggest drug cartels, which Riggs, Murtaugh, and Palmer are investigating. He was the main antagonist of season 1 and a minor antagonist in season 2.
Flores is like any other criminal and drug dealer who wants to get deals done without cops getting in the way. He's always got his second-in-command, Gideon Lyon, to carry out the secondary orders and missions.
As much as he is adamant about getting business taken care, he hates things going bad, and will stop at nothing to see that nothing stands in his way. If anyone in his organization is about to rat him, he'll slaughter them without thinking twice rather than be ratted out, even if they are family.
