Mario Superstar Baseball
Bowser Monsters is the only unlockable team in Mario Superstar Baseball. They are also sometimes called the Bowser Flames, Bowser Blue Shells, and the Bowser Blackstars. When the Sub-Captain, Bowser Jr., heads the team, it is called Jr. Fangs, Jr. Bombers, Jr. Rookies, or Jr. Pixies. The Bowser Monsters team is usable in Exhibition Mode, but is not playable in Challenge Mode until the player has beaten Special Difficulty with any team;. The team acts as the Final Boss when playing as all the other teams in Challenge Mode. Bowser Monsters always practice at Bowser Castle. The Bowser Monsters team plays a bit differently. Whereas all the other teams were trying to play a game against Bowser, when playing as the Bowser Monsters, Bowser heads out to challenge them. This is not necessary for Bowser, as he just sent out the letter but, of course, Bowser does not listen to Lakitu, and heads out to challenge them. After beating all the five teams, Mario and eight of the other Captains steal Bowser's Castle, and Bowser and his team must beat them to get them out.
Bowser's team is somewhat spread-out. He has four Dry Bones, along with the Hammer Bro and his two variants, the Fire Bro and the Boomerang Bro. The three Hammer Bro variants are counted as the same character, and are collectively unlocked by beating Challenge Mode once as the Bowser Monsters; they are the only unlockable species on any of the teams (the rest having individual unlockable characters only). All members of the Bowser Monsters have good chemistry with Bowser and Bowser Jr.. Koopa Troopas share good chemistry with Bowser and Dry Bones, Koopa Paratroopas only have good chemistry with Bowser, and Magikoopas have good chemistry with only Bowser Jr..
Mario Super Sluggers
Bowser's team is also playable in Mario Super Sluggers, where it is only known as the Bowser Monsters. When led by Bowser Jr., the team is called Bowser Jr. Rookies. The roster is somewhat similar, though Magikoopas are now available as extras. Like the previous games, all the members of the Bowser Monsters have good chemistry with Bowser, with the Magikoopas and Bro variants having good chemistry with Bowser Jr. as well. Koopa Troopas have good chemistry with Bowser, Bowser Jr., and Dry Bones, and Koopa Paratroopas have good chemistry with only Bowser. Boo also shares good chemistry with Magikoopas.
The Bowser Monsters is tied with the Yoshi Eggs for having the most players on one team.
