Though he is not in game and probably not even considered for it.I feel that he is still a relic to gaming.
I think he is a cool mascot with a niche flavor to him , he was popular but didn't get hyped to Mario , Sonic , Pacman and Megaman levels. I think being Bomberman fan now makes you fan of something that isn't in spotlight and not as vocal as Megaman fans.
He was created in 1983 and an older character than like Luigi and Megaman. Has made appearance on every Nintendo device and would have had 3ds game but Konami decision to kill Hudson off came quick and without any remorse.
Hudson's purchase was just for the IP's that Konami would never even bother to touch or acknowledge as their own. Though that isn't saying much as everything is always behind Metal Gear Solid in existence to them.
Konami wouldn't even talk about Bomberman being 30 years old , he is truly in the grave while other characters still get referenced and spirit still strives on.
People often call him a Konami rep but he has zero presence as a Konami character , if he got in at all then it would be that he was a nostalgic character of the past.
I think that he would be nice addition to smash series.Reckless character that can even take himself out , if he is not too careful like how it is in his games.
Example :
B : Bomb Drop - How he leaves bombs down in classic games and in all games really. (Staple Move)
B(hold for second) : Bomb Throw/Toss(Power Glove) - Tosses the bomb but you can also move during animation
Can also pick up the bombs with A as they were an item to retoss
B(full charge) : Pump Up - After holding it for while , you can toss huge bomb with bigger Explosion or the P Bomb , if you look at like Dream Mix TV World Fighters.
Side B : Rubber Bomb - Bounces along randomly and where it stops is anyone's game and can be unpredictable.
Dangourous Bomb : Can happen when two rubber bomb's manage to colide via kicking and causes unusual blast
Up B : Louies - The Kangaroo like animal that he had in older games that can be used to jump or take a hit , in his game they were disposable creatures that Bomberman used to keep himself from dying or utilized their abilities and jumping one could be useful one as recovery.
Bomberman doesn't really need them at all as he had several abilities like jump shoes , wings and jetpack to make himself get a distance and there is always more pets that he had then just those to choose from.
Down B : Remote Control (Bomb) - something that bomberman plants on the ground but its visible and he can kick it to make it slide around.It would be like Snake's Down B in a way but a huge mobile object that is not stuck in one location and could be used for maneuvers.
I could see someone kicking it off stage then activating the explosion making sure that someone can't make it back on the ledge or using it on people that just like to rush in.
Up Smash : Wind Bomb/Hurricane Bomb - Can drag opponent upwards from a vortex , if they are hit by it. Bomberman can just throw it upward and its lands in spot that he was standing in , which he can run away from.Its power and range depends on the charge.
Down Smash : Line Bomb/Mine Bomb - Could go for something like Snake with Mine Bomb or go with Line Bomb that places out multiple bombs and could show him trying to put them all out in front and behind him.
Side Smash : Bomb Kick - Can kick bombs that will collide into opponent with an impact and works with forming the Dangerous Bomb.
Dash or Tilt attack : Bomb Punch
(Not really getting into A moves as they could be regular attacks or more weapons and not really main highlight of moveset , probably needs punchs and kicks to have balance in the moveset.)
Final Smash : Countdown - blocks will land all on the stage as in Bomberman games , when the game doesn't have a winner when the time is running out.
Alt Colors : Black Bomberman , Red Bomberman , Blue Bomberman , Green Bomberman , Yellow Bomberman and Gold Bomberman
Out of Alt colors , Black Bomberman is most important color besides main one , leader of the other bombermans and person White Bomberman duos with several times but also was once bad guy in Bomberman Series.Gold Bomberman was just special color that was secret in several games , would be cool as unlockable.
Bomberman already legitimately fits the whole Red Blue and Green team thing , not that it matters anymore with outlines but you could still consider it cool that he doesn't need any stand in alt colors at all.
Stages : Bomberman has a lot stages to base design off but they could have something classic and just have his stage transition between stage appearances.
Music : Bomberman's music had that upbeat catchy sound to it but also had digital sound to it. Not what people normally use now in video games.
I think that it would be fun to play someone like him but he just has 0.00% chance.The game is already done by now. When someone has chance to beg Sakurai about a character , its like Ridley , Palutena , Mii , Mewtwo and the other mascots that we currently have in the game.
While things like that doesn't shape his decisions , he considers it while he ignores some others as his mind is already made up about them. It would be funny if he didn't even know who the character was at all but its not surprising in the least.
