King Bob-omb

"Incredible! You made it this far even without a mustache."

- Big Bob-omb

Big Bob-omb, sometimes called King Bob-omb, because of his crown, is the king of the Bob-ombs. He's the first boss who is fought in Super Mario 64 and Super Mario 64 DS. Guarding the Power Star, which Bowser entrusted him with, he will not give it up without a fight.

Super Mario 64
In Super Mario 64, Mario merely has to run around to the back of him, pick him up, and toss him 3 times. Only then will he give up the Star. If he is thrown off the mountain, he will accuse Mario of cheating and he will have to start over. He is super-kind for elders, a trait not seen in many Mario series characters.

Super Mario 64 DS
In Super Mario 64 DS, he is fought twice. The first time is as Yoshi, and instead of picking him up, Yoshi had to grab the Bob-ombs thrown at him with his tongue and spit them back at him before they explode in Yoshi's mouth. After being hit by three Bob-ombs, he's defeated. The second time, he can only be defeated by one of the three plumbers and use the same strategy used in Super Mario 64.

Mario Party 2
In Mario Party 2, he appeared in the background of Mystery Land, stuck in a sinkhole.

Mario Party 5
He made a cameo appearance in Mario Party 5 in the minigame Defuse or Lose, where the players had to defuse wires leading to him by Ground Pounding them.

Mario Party Advance
In Mario Party Advance, he is the leader of the Bob-omb Mafia which protects Shroom City.

Mario Party 8
He made a reappearance in the Mario Party 8 minigame You're the Bob-omb. He blows up when the right wire is detonated (or in this case the wrong wire, as doing so will cause the player to lose the game).

Mario Kart DS
In Mario Kart DS, Big Bob-omb is a boss in Mission Mode. Similar to Super Mario 64 DS, the player have to pick up Bob-ombs and throw them at him as Wario. However, his move set is altered to fit the whole Mario Kart move set. He is in Mission 5 in Mario Kart DS.

Mario Golf: Toadstool Tour
He also appeared in Mario Golf: Toadstool Tour on a golf course in Peach's Castle Grounds. Hitting him will make him explode like a normal Bob-omb. In ring shot mode, the golfer must hit a ring he's wearing to complete the hole successfully.

Mario Superstar Baseball
He became an item in Mario Superstar Baseball in a minigame and produced around 400-500 points causing fireworks to appear.

Mario Super Sluggers
In Mario Super Sluggers he is a stage obstacle on the Bowser Castle stage, which he throws Bob-omb down onto the field. Here he rides a vehicle similar to the Koopa Clown Car.

Personality
As a king, Big Bob-omb tries to act in a royal way. He is very critical and acts patronizingly towards everyone who are of lower class. He, along with kings like Goomboss and Chief Chilly, admire mustaches almost more than anything, which leads to the fact that he despises anyone without facial hair. As he is an ally to Bowser, Big Bob-omb could be considered evil, although as implied during the events of Mario Party Advance, he actually leads the society of the Bob-omb Mafia to protect the Shroom City.

Trivia

 * Bob-omb Buddies fear him because of his big gray mustache.
