The Phanatic rides around on an ATV.
 During games, the Phanatic wanders the stadium, greeting fans and humorously mocking supporters of the opposition.
The Phanatic performs a number of regular routines on the field before the game and between innings.
Some of these routines are:
Taunting the visiting team by dancing provocatively in front of their dugout, mocking the actions of their players, and smashing or stomping on an object, such as a batting helmet, representing the team.

Standing on the roof of the Phillies dugout between halves of the seventh inning for "The Phanatic Dance" and remaining on the dugout roof for the home half of the inning to "hex" the opposing pitcher.

Warming up in the bullpen.

Shooting hot dogs into the stands using a pneumatic gun attached to his ATV.

Visiting the various broadcast booths and committing various pranks such as pouring popcorn on the broadcasters, spraying Silly String on them, or serving them Philly cheesesteaks.

Buffing the heads of any bald fans who happen to be sitting near him in the stands.

His mother, Phoebe Phanatic, occasionally appears on-field with the Phanatic.
He also has a younger cousin Phred, and a girlfriend Phiona who are rarely seen.
His father has never been identified.

The Phanatic's favorite umpire was the late Eric Gregg, a Philadelphia native, and he would greet him enthusiastically on the field when Gregg was in charge.
Gregg would often play along with the Phanatic between innings, sometimes dancing with him or otherwise participating in his routines.

One week before the Phillies had their 2006 opener, the Phanatic was "dyed" red as part of the team's week-long promotion to "Paint the Town Red".
 He was "dipped into a special paint" made by a team sponsor MAB Paints (now Sherwin-Williams) and changed from green to red.
 He returned to his regular color in time for the season opener for that year.
 This was repeated for the 2007 season, as he became red at a Philadelphia Fire Department station to help raise funds for smoke alarms in Philadelphia, raising over $4,000. "
Paint the Town Red Week" has been repeated prior to the 2008, 2009, 2010, 2011, 2012 and 2013 seasons.

There is a running gag where the Phanatic humorously mocks opposition players and they would steal his ATV keys in retaliation.
However, the Phanatic's antics are not always popular with opposition players and coaches.
During a September 1982 game, Cardinals outfielder (and former Phillies player) Lonnie Smith did not take kindly to the Phanatic’s taunts and tackled the mascot mid game out of frustration.
Dodgers' manager Tommy Lasorda in particular did not like the Phanatic's mocking of the Dodgers.
In 1988, he assaulted the Phillie Phanatic during a nationally televised game after the Phanatic stomped on a life-sized dummy wearing Lasorda's uniform (reportedly provided by Dodger infielder Steve Sax).

The Phanatic also has the dubious distinction of being the most sued mascot in sports.
In 2010, a woman filed suit claiming that the Phanatic injured her knee at a minor league game.
