Porter Clarke is Shane's older brother. Porter is a successful businessman, was concerned about Shane's seeming lack of a sense of responsibility, and paid him a visit, lecturing his younger brother on the matter.
After accidentally discovering that Shane was the Red Ranger, however, Porter gained significant respect for Shane, realizing the measure of responsibility that his younger brother had taken upon himself. This encounter is important in Power Ranger history, for it shows that not only is the existence of Power Rangers known to the world at large, but that people are also aware of specifics regarding them.
Porter was especially proud of the fact that not only was Shane a Power Ranger, but that he was the Red Ranger, acknowledging the fact that Red Rangers are traditionally the leaders of Power Ranger teams.
- He is the fifth person who is related to the Power Rangers and found out that his family member is a Power Ranger.
- Porter Clarke was played by Robbie Magasiva, Pua Magasiva's (Shane Clarke) real life older brother. This makes him the second character who is played by a Power Ranger's actor's real life brother after David Trueheart who was played by Jason David Frank's (who plays Tommy Oliver) late older brother, Erik Frank.
