The "Acceleration Ace of the Motor City", super speed is Michael Hendrie's forte. In his guise as M.P.H, he has developed an impressive reputation which earned him full membership in the prestigious Honor Guard. His genetic makeup might be a clue to the source of his abilities, since his nervous system has been 15% over-layed with alien D.N.A.
M.P.H. has been a member of Honor Guard since 1991 taking part in many of their activities over the past twenty years. One of the earliest battles he took part in with the group was facing the recently awakened Destructoids in 1991 in Astro City.
A few weeks after that M.P.H. was alerted by a silent alarm to the Junkman's attempted robbery of a bank in Detroit. This is one of the few times where the super-speedster has been taken. The elderly Junkman used clever gadgets combined with science, like static adhesion marbles that multiplied to incapacitate M.P.H.
In the Summer of 2000, along with Honor Guard, he helped to rescue actor Mitch Goodman, who became a national celebrity after some minor exploits in the guise of the Crimson Cougar. The Unholy Alliance, representing interests who don't want to see more people taking up being costumed heroes, tried harming Goodman to send a message, but were ultimately thwarted by M.P.H. and Honor Guard.
One of his key relationships on Honor Guard is his friendship with Beautie. In 2008 Beatuie's programming was overriding itself constantly in an effort to find "her parents." M.P.H. took a personal interest in Beautie's struggle to figure out who she is and where she came from. He took to following Beautie in his spare time and giving her information on where to find where she came from. He eventually witnessed Beautie being rejected by her "mother" Elaine Girbachs, which had happened multiple times. M.P.H. told Girbachs that her "daughter" needed her and left with the hope that the next time maybe Beautie visits, Girbach's will take Beautie's feelings into consideration.
At some point during the late 1990s or 2000s, M.P.H. had a short-lived relationship with Quarrel. While they enjoyed each other's company, Quarrel broke things off when she realized she had neither the time nor energy to reciprocate M.P.H.'s commitment to the relationship.
He has super speed, reflexes and possible senses.
Chest Harness- MPH's bulletproof, speedometer-styled chest harness has certain technological capabilities of unknown nature. Presumably it is a powerful resource, as the Junkman considered it important to disable the harness during a clash with MPH.
His middle initial may be "P."
