I'm just gonna skip NES games since they made funkitized versions of them for the SNES anyway.
SNES Games
Super Mario Bros 1
This is the first game in which Bowser ever appears! The story's pretty simple: He's kidnapped the princess and turned everybody in the Mushroom Kingdom into blocks and mushrooms and stuff. And he has like a million castles and in each one he's holding some Mushroomers captive, but in the last one, he has the princess.
My Comments: Uh, well, this game is good. And it's......good. I've never beaten it though....it's just so old that it doesn't fall within my skill range I guess. Or maybe it's because there's not enough power-ups. Or maybe it's because Bowser just roxors and I could never beat him because I am a mere foolish mortal. Yeah, it's the last one.
Super Mario Bros 3
Bowser came up with an even better plan than before: to have his each of his seven kids take over each of the seven countries in the Mushroom Kingdom! And just incase that annoying Mario DID happen to beat all of them, he had a back-up plan: kidnap the princess to lure Mario into his secret valley full of deadly warships!
My Comments: Well, uh, I think Bowser's really cute in this one. I mean, even moreso than the other games (if that's possible). Also, lemme brag. I've beaten this entire game twice without using a single whistle.
Super Mario World
His kids were disappointed at their first loss, so he decided to give them another chance at beatin the pants off Mario: they would each take over one of the seven sections of Dinosaur Land, and Bowser would take care of all those Yoshis by trapping them in eggs. And again, if Mario happened to beat them all, Bowser would just wait in his secret valley full of even more obstacles for Mario!
My Comments: How come Bowser's skin is green in this one??!! I don't get it!!
Super Mario World 2: Yoshi's Island
Now this one is going way back in time....all the way to when Bowser and the Mario bros were babies! Bowser's babysitter Kamek foresaw that the two babies would one day defeat little King Bowser, so he attempted to snatch them from the stork. Unfortunately, he only got Luigi, and Mario fell safely down to Yoshi's island where the Yoshis decide to return him to his parents. At the end you get to see Baby Bowser and boy is he so CUUUUTE!!!
"What kind of gween donkey is dat? Me wanna wide! MINE!! MINE!!" - baby Bowsie
My Comments: So, this is pretty much my favorite Mario game ever. Maybe it's the scenery, or the music, or the gameplay, or the INCREDIBLY ADORABLE BABY BOWSER WHO'S SO CUTE AND CUUUUUUUUUUTE, I can't decide which.
Super Mario Kart
Bowser decided to take a break from all his evil plans and go go-kart racing. But before the race he must have had to go up to Mario and say "Well, I have tried to beat you to a pulp and take over your whole kingdom a million times, but it's all cool, right?"
My Comments: Bowser's winning music is so cool. He rules. His music rules. Bowser, overall, RULES.
Super Mario RPG: Legend of the Seven Stars
In this game, Bowser is.....drumroll......on Mario's side!! Why? Because this mean, mean meanie named Smithy destroyed his castle and in order to get it back he has to save these seven star things and...oh fooey, I dunno the whole story, but the point is he has to work with Mario and Mario's homies!
My Comments: Well, considering I've never played this game.....*sheilds herself from bombardments of pop cans and tomatoes*.......I don't think I can make any comments. I have read some of his quotes from this game online though. Love 'em. Bowser's hilarious!
N64 Games
Paper Mario
Bowser steals this Star Rod from Star Haven which makes him invincible and able to do magic. He also holds all of the star spirits that once guarded that star rod thingie captive inside cards. Then, just to keep his reputation, he also kidnaps the princess, well actually, he steals her castle by making his rise up outta the ground carrying hers. Cool stuff, I know. So, Mario's got a lot to do!!
My Comments: This game is very well-made I must say, a fine Mario product for any fan to enjoy. I can calmly say that this a good, well-thought-out Mario game and.....OK....I can't take it any more........BOWSER IS SOOOOOOOOOOOOOOO CUUUUUUUTE ON THIS GAME!!!!!!!!!!!!!!!!!!!!!!!!!!!! That's really all I wanted to say. That and, he seems evil..er than usual on this game, making him all the more loveable of course!!!!
Super Mario 64
Bowser wanted to kidnap Princess Peach whose voice was about a thousand volume units lower in pitch than it is now. So, he stole the Mushroom Kingdom's Castle Stars so he could enter a secret world inside paintings and hide there waiting for Mario to challenge him. Betchu wish you could go inside paintings. Especially Mona Lisa, so you could tell her to stop staring at you.
My Comments: OK, the way in which you must defeat Bowser on this game is SOOOOO MEAN!!! Like it's so mean, that I won't even do it. I can't even bring myself to do it. It's like, so what he kidnapped the princess and stole the castle stars and whatnot you don't have to throw him into spiked bombs gosh darn it!!!!!!!!!
Gamecube Games
Super Mario Sunshine
For some reason, Bowser all of the sudden has an eighth kid, Bowser Jr. (or maybe he's one of the seven who was renamed later on, who knows). He gives Bowser junior a magical paintbrush that will allow him to disguise himself as anything, and he disguises himself as Mario! He also uses the paintbrush to cover the entire island of Isle Delfino with icky paint. The plan here is to frame Mario for dirtying up the island so the residents will put him in jail so he'll be unable to interfere with Bowser's plans....hehe....which are, as usual, to take over the Mushroom Kingdom.
My Comments: I hope someday I'll beat this game, cuz honestly, right now, I'm stinking. S-T-I-N-K-I-N-G. I stink at this game. Wanna know how many flippin' shine sprites I have? 13!!! That's right!!!! A mere 13!!!!!!( unlucky number, might I add.....-_-) Believe me, I'd like nothing more than to see my beloved Bowser in a hot tub. But I, sadly, am 62 shine sprites away from it. Dang, dang, dang, dang, dang, dang!!!!! They couldn't just make this dang game a little dang easier for dang people like us who are dang used to dang side-scrollers? Dang?
Mario Kart: Double Dash
Bowser's so proud of his new son that he decides to take him Mariokartin'! In this cool new game, you get to have two dudes on one kart, one to drive, and one to throw junk at the other riders!
My Comments: Best. MarioKart. Game. Ever. Gued. To. The. Screen. Can't. Stop. Playing. Bowser. Is. So. Cute. What. Dang. Function. Key. Do. I. Have. To. Press. To. Get. This. Auto. Period. Function. To. Stop.
Mario Power Tennis
Wario and Waluigi were disqualified from the tennis tournament, so Bowser decides to help them get back in by letting them practice in his secret underground tennis lair. Once the final match is about to take place, Bowser replaces the original competetors, Yoshi & DK with the W-brothers, who start shootin Bob-ombs at everyone. Mario, Luigi and co are able to hit the Bob-ombs back with their tennis rackets. Bowser gets mad so he throws his own Bob-ombs and Bullet Bills at em. Him, Wario and Waluigi end up blowing up the entire tennis stadium, and yet Toadsworth still lets the three of them compete in tournaments! Awesome!
My Comments: Bowser's voice is loveable beyond reason. This, along with Toadstool Tour golf, is the best use of his voice, IMO. Don't you think it's ironic that he's voiced by a guy named Scott Burns----when that's what Bowser does best? He BURNS!!! I also love the little movie that plays when he wins. Hehe, he wants a kiss from Peach. What dumb chick wouldn't wanna kiss Bowser?????
Paper Mario 2: The Thousand Year Door
In this one, Bowsie isn't the main villain.
This creep named Grodus is. Grodus kidnapped the princess, and boy is Bowser ticked!! Kidnapping Peach is HIS calling card!! Meanwhile, Mario is a-lookin' for these shiny things called the Crystal Stars cuz that's what Peach was doing when she got ripped off. He figures they'll lead him to her. The best part is, at the end of each Chapter, you get to see how Bowser's doin' on his quest to kidnap Peach back, you even gain control of him and get to play SMB games!!
My Comments: Best Mario game ever made. Period. Seriously. I actually cried tears of joy about this game----twice!!!! The part where you find out Koops' Dad is still alive, and when Prince Mush is reunited with his sister!!! Call me a wuss, or call the game genius. Whichever one. Also, about Bowser, this game brings out his more hilarious side. Gotta love him.
Mario Golf: Toadstool Tour
Bowser, Wario and Waluigi are at it again!! The W-dudes can't seem to get one ball in the hole so Wario goes bonkers and hits it real far. The ball ends up
hitting poor Bowser in the eye!!!! So Bowser gets in his Clowncopter and starts shooting junk at them. (Serves them right!!) But right when Bowser's about to throw a Bob-omb at him, Mario hits a golfball and it hits it, and Bowser ends up blowing up part of another Mario sports center!!
My Comments: BOWSER SPEAKS. I can't believe it, usually when you hear his voice it's just assorted loveable growls and evil laughs, but now, behold----HE SPEAKS WORDS!!!!!! If you taunt your opponent in match play, you get to hear Bowser say, "I rule!!! Heh heh heh!!!" or "Amateur!!" or "Go!" or "Do it!!" Awwww.....Bowser says his first words!!!
Super Smash Bros Melee
A bunch of all-star Nintendo characters must be really ticked at each other for some reason because they all decide to get together and beat each other up!! Bowser is one of them, of course, and he's basically the best player on the game, too.
My Comments: Behold Bowser----more ripped and realistic-looking than ever before! This, so far, is also the closest you'll get to playing a Bowser adventure game starring Bowser. So, enjoy it. I SAID ENJOY IT, WEAK FOOLS!!!
Mario Party 6
The sun and the moon, Brighton and Twila, got in a fight over who's better. So the Mario gang decided to settle it by collecting a bunch of stars (how that'll help, I don't know....0_o). So they get ready to partAAY! Unfortunately Mario didn't invite Bowser to his party 


, but he has to have learned by now that Bowser ALWAYS shows up uninvited to cause trouble!!! BWAHAHAHA!!
My Comments: Upsides of this game----it's MUCH easier to land on a Bowser space than in MP5, and Bowser has a real voice, and has his own game called Seer Terror. Play Seer Terror, it's a riot. Seriously, I stayed up till midnight one night playing Seer Terror over and over again. That's how much it rules.
Mario Party 5
Bowser is gonna ruin everybody's assorted dreams about different stuff like candy, toys, outer space, the sea, and......pirates......OK then......and he's gonna fill them with his own nightmares, with the help of his Koopa Kid minions. It's up to Mario and his pals to save these dreams! Not that that's a good thing.....
My Comments: Bowser's role in this game is bigger than any of the other Mario Parties, which automatically makes it the best. The downside is, it's almost impossible to land on a Bowser space. Seriously, I actually calculated the odds of landing on one, and it was like, 0.003%. I'm not even joking. Thus making the odds of playing a Bowser mini-game one fourth of those odds. Yeah, OK, I know landing on a Bowser space is supposed to be a bad thing, but Nintendo's gotta know by now that Bowser has a cult following!!!!
Mario Party 4
Bowser's role in this one is the same as MP 6. The story here, however, is that Mario characters have come to celebrate your birthday!!! Wha???!! How did Mario characters find out when my birthday is??? Am I..........getting stalked by Mario characters? *Sees Mario walk into her room* Mario: "Hey Apricot, you's lookin' pretty sweet today, baby." AAAAHHHHHHHHHHHH!!!!!!!!!!
My Comments: Three words: I......WANT......BOWSER!!!!! Where is Bowser? I haven't even seen him on this game yet!!! Ya know, I land on a Bowser space, and I rejoice cuz I'm gonna see Bowser.........and then Koopa Kid comes along. What kind of a super bummer is that???
Gameboy Advance Games
Mario & Luigi Superstar Saga
This evil witch named Cackletta has stolen Princess Peach's voice in order to use it to get a response from the legendary "Beanstar" which will grant her any wish!! Since Peach is now speaking in conbustibles, Bowser can't kidnap her, dang it!! So he teams up with Mario and Luigi to help Peach get her voice back. Sadly, while they're all on their way to the BeanBean Kingdom, Bowser's sweet Koopa Cruiser explodes, and Bowser falls into a cannon, which he later gets shot out of because the owner was tired of him complaining (OOOOH!!!! POOR BOWSER!!!!!!!!!) But don't worry. He's a-okay, except he gets amnesia and joins up with a thief named Popple who is in need of a bodyguard. And, I'm not gonna give any more away!! You play the game if you wanna find out!!
My Comments: Poor Bowser is all I can say. POOR BOWSER. First he gots shot out of a cannon, then he loses his memory and becomes a slave to a thief, then he gets his body possessed by an evil witch and----ooops.....did I just give that away?
Mario Party Advance
Bowser has stolen all the games and Gaddgets from Party World and scattered them around Shroom City!! No, I didn't put exclamation points to say that's a bad thing!! It rules!! Bowser's a genius!!! So, Mario, Luigi, Peach and Yoshi are on their way to help out the Shroom City locals to get their mini-games and Gaddgets back. Bowser has quite a few cool quests for them as well. Also, in this game we find out that Bowser actually has an unlimited supply of Koopa Kids, as opposed to just four, and that they aren't his sons, they're his hired-hand minions.
My Comments: The softer side of Bowser's personality comes out a lot on this game. He actually has a quest called "Bestest Buds" (That meaning you and Bowser!) where you have to go buy him a gift to "warm his cold heart". That's so touching!!!! And also, if you get enthusiastic about beating him, he says that you have good spirit!!! Let's just think about this. He said that you have GOOD SPIRIT for wanting to BEAT HIM. That was a pretty nice thing for him to say!!! You better thank him!!! Also, if you ever run from one of his quests, he gets all sad and disappointed says stuff like "Awwwww....I was ready to play, too....."
