Behaving Like an Animal with Every MLB Mascot

Humblebrag: I’ve got to meet every MLB mascot. Each one is a character. Many I’ve met at ballparks, but even more I’ve met at events like the Major League Baseball All-Star Game fan festival. Meeting them all is pretty cool. Most of them behave like animals!

Of the 30 MLB teams, only the Yankees, Dodgers and Angels lack a mascot. Yet, across time, they’ve had other characters pinch hit. Mascots who are not fan favorites occasionally get cut so hot prospect mascots can make an appearance.

Get to know the MLB mascots. They are all unique. Most are fuzzy and tall. They are all charismatic and love to take selfies. Maybe someday, you can get to know them in person, too!

1. D. Baxter – Arizona Diamondbacks

The Diamondbacks’ mascot was created by Brently Bell, the son of Jay Bell, one of the original players during the teams inaugural season in 1998. D. Baxter the Bobcat has double meaning. First, “D. Baxter” comes from the team’s short name, the D-backs. Then, “The Bobcat” comes from the original name of the stadium where the Diamondbacks played, Bank One Ballpark, nicknamed The Bob. Plus, bobcats are prevalent throughout Arizona. Baxter is known to be highly energetic and mischievous.

His favorite songs include “Take Me Out to the Ballgame,” “Georgia on My Mind,” “Midnight Train to Georgia,” and “The Devil Went Down to Georgia.” Blooper succeeded the “Homer of the Brave” mascot after he went into retirement.

Homer was the mascot of the Atlanta Braves from 1989 to 2017. Homer’s full name is Homer the Brave, named after both lyrics from the national anthem and the nickname for a home run.

This anthropomorphic purple triceratops dinosaur can spin his head all the way around, a crucial skill required to witness all the home runs hit within the mile high altitude in Denver.

11. Orbit – Houston Astros

Orbit is a lime-green alien who wears an Astros jersey with antennae extending into baseballs. As far as we know, Orbit is the only mascot who admitted his own guilt of murder! During the last game of the 1999 season, Orbit zapped the other Astros mascot, General Admission, with an alien ray gun and killed him!

General Admission would often fire a cannon from his outfield platform to scare those seated near him. After the killing of General Admission, Orbit served his time. From 2000 through 2012, Junction Jack was the Astros mascot, which coincided with the Astros moving from the Astrodome to then Enron Field. When the Houston Astros made their move from the National League to the American League in 2013, Orbit was released and made his return. He has been beloved by Astros Nation ever since.

12. Slugerrr – Kansas City Royals

Sluggerrr, the King of the Jungle, measures up at 6’9″ and made his debut in 1996. His name is derived from the the word slugger, which is a powerful batter.

Slugerrr once injured a fan when he fired a hot dog into the stands and pelted him in they eye. The spectator sued the Royals, claiming that were negligent. A jury found for the team under the Baseball Rule, which limits spectators’ ability to sue teams for injuries arising from gameplay, but the Missouri Supreme Court reversed that decision, holding that a mascot’s hot dog toss is not an essential part of baseball. On retrial, a new jury found that neither the team nor the fan were at fault, and awarded no damages. Welcome to the jungle.

13. Rally Monkey – Los Angeles Angels

While the Angels are 1 of 3 MLB teams without an official mascot, the Rally Monkey debuted in 2000. During a tight game, video board operators took a clip of a monkey jumping around from the Jim Carrey movie “Ace Ventura: Pet Detective” and superimposed the words over it: “RALLY MONKEY!” The video was so popular that the team hired a white-haired capuchin monkey to star in original clips in future games. In 2009 when the Angels reached the post-season, the rally monkey’s popularity was renewed.

14. Bobblehead Character – Los Angeles Dodgers

While the Dodgers are 1 of 3 MLB teams without an official mascot, the Los Angeles Dodgers showed off a new mascot at the team’s home opener in 2014. The team claimed the big-headed fellow in a Dodgers jersey wasn’t a mascot, but was a “bobblehead character.” Ohhhh.

While the bobblehead character may have been short-lived as a mascot, a giant-sized larger-than-life ceramic bobblehead can still be found at the upper level of Dodger Stadium as recently as 2022.

16. Bernie – Milwaukee Brewers

In 1970, when Brewers attendance at Milwaukee County Stadium was low, Milt Mason, a 69-year-old Brewers fan, swore to sit atop the scoreboard until the team could draw a home crowd of 40,000. It took 40 days. In front of a crowd of 44,387 on August 16, Mason descended from his trailer following a Brewers 4-3 win vs. the Indians. He died in 1973 as the original Bernie Brewer.

The Bernie Brewer mascot was a tribute to Mason, appearing as a cheerful man with a big mustache. In 1973, a beer-barreled chalet was built for him inside the stadium where he led the crowd in cheering. Following each home run and victory by the Brewers, he slid down and plunged himself into a huge beer mug in celebration. Bernie Brewer was a fixture at Brewers games until 1984 when the Brewers built new bleachers to replace the chalet, forcing Bernie in retirement. In 1993, by popular demand, Bernie Brewer returned in a full-body costume of a man, including a large foam head. The chalet was also rebuilt above the left-center field bleachers.

32. Domingo Ayala – Greatest Semipro Baseball Player

Domingo Ayala, through his silly baseball antics, is a symbol. He embodies everything great about baseball. In a game of failure, Ayala allows people to laugh at themselves as he reminds us that baseball, no matter how caught up in it we may become, is still just a game. Though not an MLB mascot, Domingo Ayala has been the face of amateur baseball since 1999 when he uploaded his first YouTube video.

At the age of two, Domingo Ayala started playing baseball. Soon, he became one of the best players in his hometown of Puerto Plata, Dominican Republic. In his pursuit to make it to the MLB, Ayala packed his bags and moved to the United States.

Now, the self-proclaimed best baseball player in the world still claims to be 17 years old. Though many believe him to be slightly older, no one has seen a birth certificate to disprove his claim. As he travels the world teaching baseball, his ultimate goal is still to make it to the big leagues. The last several years, he has made it to the MLB All-Star Game, and makes his rounds at Play Ball Park within the fan fest.
