A lot of times video game enemies become staples in games. Usually these enemies are included in most of the games. However, some enemies only appear in one game and do not appear in future games. Even iconic video game franchises such as Mario, Mega Man, Sonic, and Kirby have one time and done enemies. Mouser is a character that has only appeared in one Mario game. Since then he has not appeared or made a cameo appearance in Mario Games.

Mouser originally debuted in the Japanese game Doki Doki Panic. When that game was converted into Super Mario Bros 2 a lot of the enemies where carried over. Mouser was one of the bosses and enemies carried over into Super Mario Bros 2.

In Doki Doki Panic and Super Mario Bros 2 he was likely created by Wart to be a monster. In both games he serves the evil dictator Wart who has taken over Subcon. In Doki Doki Panic Wart has kidnapped 2 of the families relatives. In Super Mario Bros 2 Wart has captured some of the Subcon fairies and imprisoned them.

The booklet says he destroys good dreams with his bombs. This implies his role is to create nightmares for subcon residents, who enjoy dreaming peaceful dreams. In addition, he also serves as one of Wart's guardians. In Doki Doki Panic he is fought three times. In the original Super Mario Bros 2 game he is fought in world one and three.

After Wart is defeated Mouser's fate is unknown. Unlike other enemies he did not go to work for Bowser. In fact, he does not appear in future games, and he does not even make a cameo appearance. It is speculated that when Wart was defeated Mouser vanished since he was created with Wart's dream machine. That theory could be true as Mouser along with Claw Grip and Triclyde do not appear in future games. In some versions the booklet states all three where created by Wart.

Appearance- Mouser is a giant Mouse or rat. He is gray colored and has a pink tail. It seems like he wears either red or white gloves depending on the version of the game. Moreover, he wears sunglasses over his eyes.

Personality- The booklets state he is proud and prideful. He does not see himself as a regular mouse. He enjoys causing misery to others. He loves it when he creates nightmares with his bombs as he says in later games here have some bombs. He is very confident and does not think he can be defeated. This would also make him very arrogant. Furthermore, he has no remorse for his actions because he likes agony and suffering. However, he is loyal to Wart and will serve him no matter what.

Another part of his personality is he cannot stand it when his bombs are used against him. When the player throws his bombs back at him and they explode on him. Mouser will shout arrggh or agony. In later versions of the game after being defeated he shouts NO WAY. This is due to him being over confident and arrogant. Also, he can dish it out but he cannot take it. He cannot stand it when his own weapons are used against him or when he is defeated.

Abilities- Mouser is able to move back and forth at a very good clip. He can also speed up such as the second time he is encountered he moves much faster. He has an unlimited supply of bombs. He can throw his bombs one at a time, or start spamming them. Furthermore, he can get several bombs to land in the same place creating a cluster. He is somewhat durable. The first time it only takes 3 hits to take him down. The second time it takes 6 hits to take him out.

Attacks- He throws lots of bombs. He can throw a single bomb at the player while moving back and forth on his platform. He can also throw several bombs at once at a rapid rate. This can create clusters of bombs that can cause a lot of problems to players.

Weaknesses- He is weak to his own bombs. Mario and Luigi can catch his bombs before they land and throw them back at him. He cannot stand it when his bombs hit him and explode on him. The other characters can pick the bombs up from the ground but this is risky. The player will need to quickly throw the bombs back at him.

Relationships

Allies

Wart- He was likely created or created by Wart to be a nightmare monster depending on the version of the game. He understands his role very well. He loves spreading terror on Wart's behalf. He serves Wart and is very loyal to him.

8-Bits- He is on good terms with Wart's 8 bit gang or army. They see each other as comrades.

Triclyde and Claw Grip- Like Mouser they are fellow guardians of Wart. They all respect each other and see each other as comrades.

Enemies

Mario- He is enemies with Mario because Mario can throw his bombs back at him.

Luigi- Like Mario Luigi can easily catch or pick up his bombs to throw back at him.

Toad- He does not like Toad because Toad is helping Subcon defeat Wart.

Peach- He does not like Peach because she is helping Subcon defeat Wart.

Mouser is a monster made to create nightmares on the behalf of Wart. However, after Wart is defeated Mouser is not been in a Mario game since then. Thus, he is a one time and done character. Despite being a one time and done character he has made his mark especially in Super Mario Bros 2. This makes it likely after Wart was defeated he vanished like a bad dream.

However, the Robber Mice in Yoshi's Island and Mice in Paper Mario kind of resemble him. The mice in those games wear sunglasses or a masks to cover their eyes. It is likely that Mouser may have served as the template for those characters as they are similar in design. The main difference is Mouser is a giant mouse/rate compared to the others. Regardless, it is likely Mouser at least inspired the creation of these characters. This concludes the Mouser Biography.
