Bomberman Portable

Stages

Bomber World / ボンバーせい

This world features no gimmickry.

Stage 1-10 (boss)

This battle is against 3 Mecha Bombers (メカボンバー). They typically walk 2 to 4 steps before placing a bomb, which has a 2-tile blast radius. They are equipped with a Bomb Kick, and on rare occasions may kick one of their own bombs forward. They occasionally become tired, temporarily immobilising them. They do not have collision damage, and are safe to walk through.
Requires 4 hits each to defeat. 2000 points each.

Green Wood World / グリーンウッドせい (Jungle World)

This world features foliage that will hide anything inside it from view.

Stage 2-10 (boss)

Spiderer (スパイダル) will make a few steps in one direction towards Bomberman's location, before stopping and launching 4 bombs into the air, which land in a cluster close to Bomberman's position. Its eye opens during this attack, and closes once its bombs detonate; the boss can only be damaged by bombing it in the eye.
Its bombs begin with a 3-tile blast radius, but after 5 hits, their radius extends to 7 tiles. Its bombs cannot land in the bottom row of tiles, and so long as you are standing to the side when its eye closes, you can prevent the boss from encroaching on that lane.
Requires 7 hits to defeat. Worth 5000 points.

Yellow Desert World / イエローデザートせい (Desert World)

This world features warp holes, depicted as quicksand; entering one will relocate Bomberman out of another random warp hole.

Stage 3-10 (boss)

Sorcery (ソーサリー) will move a few tiles towards Bomberman (erasing any bombs it collides with) before performing one of two attacks.
Its body will rotate before it rises into the air and drills into the ground on Bomberman's current position. The screen will shake, and it rises a few seconds later, shooting a harmful projectile in Bomberman's direction; wherever Bomberman is standing when the screen first begins to shake is where it will rise. The boss cannot be harmed during this attack phase until its animation has fully completed. If the projectile touches a bomb, the bomb will detonate and the projectile will be destroyed.
Its other attack is to tuck its body around itself in a circle, and float in a straight line towards Bomberman's current position, redirecting towards his new position after touching the arena's wall. Will cease doing this after being bombed, or after a random number of times touching the wall.
Requires 7 hits to defeat. 5000 points.

Black Horror World / ブラックホラーせい (Spook World)

As you destroy more soft blocks, the screen will darken.

Stage 4-10 (boss)

Buggler (プロフェッサー・バグラー) moves two tiles at a time, typically stopping to do an attack at every other junction.
He will first spawn two Gargoyle enemies to roam the arena. If both Gargoyles are defeated, Buggler will spawn them again at the next opportunity.
Will stop and throw two bombs 4 tiles out from his left and right, with a 3-tile blast radius. Buggler is shielded during this attack, and cannot be harmed until after the bombs detonate and he lowers his arms. After 5 hits, the blast radius of his bombs will increase to 8 tiles.
Requires 6 hits to defeat. 10000 points.

White Ice World / ホワイトアイスせい (Ice World)

This world features slippery ice; after stepping on it, Bomberman will not stop moving until he touches a solid object.

Stage 5-10 (boss)

Bigalon will move slowly, typically strafing Bomberman's position, erasing any bombs it touches.
If Bomberman is standing to its side, it will throw its hammer in an arc like a boomerang. Its hitbox is deceptive, and it can harm Bomberman even when standing close to Bigalon's side; moving far away, or standing right in front of Bigalon, seems to be the safest options.
If Bomberman is in front of Bigalon, it will strike its hammer in a 5x5 span in front of it, damaging Bomberman. After 5 hits, the range of it hammer strike appears to increase.

Bigalon will never do the same attack three times in a row: this means if you goad it into two hammer strikes, its next attack will be the boomerang throw, so stand clear! It's recommended to equip at least 2 Speed Ups if you intend to bait its hammer strikes and be able to outrun them.
Requires 10 hits to defeat. 10000 points.

Red Lava World / レッドラバーせい (Lava World)

This world features gaps instead of hard blocks (marked as red on the maps), meaning bomb blasts will extend over them. Another hazard are breakaway tiles, which can be identified by their yellow borders; they will fall after being walked over, rendering the tile impassable.

Stage 6-10 (boss)

Spriggan will slowly move left and right at the top of the arena, and cycle between its two attacks.
First, it will launch its two fists forward; their range spans 5 tiles in front of the boss. (technically it only covers a 1x5 tile span, but if the boss is ever so slightly off-centre, you can still be harmed even if you're standing to the left or right of its fists. don't get overconfident!)
After moving again for a little while, it will then extend its arms and spin them as it drifts in a straight line towards Bomberman's current position, before retreating. Spriggan's hitbox spans a 10x10 tile area during this attack, so stand well clear.

Despite appearances, this is not an "open plan" arena like the previous boss fights, but a grid with breakaway tiles.
Spriggan's body spans 3x2 tiles, and each of its fists 1x2 tiles; you can stand between the body and the fists, but it's a lot of trouble for very little benefit. Spriggan cannot walk through bombs except during its spin attack, and will cycle its two attacks until the bomb is gone.
The boss's default movement speed will increase after every hit; this does not effect its speed during its spinning attack.
Requires 7 hits to defeat. 15000 points.

Light Electro World / ライトエレクトロせい (Electro World)

This world features electricity panels; they activate every 3 seconds, lighting up for 1 second and stun Bomberman for just as long if he steps on them.

Stage 7-10 (boss)

Rangey will move in one direction and slowly follow Bomberman, attempting to keep him in front of itself, or on its cardinal directions.
It will periodically open its door (which can also harm Bomberman on contact). If Bomberman is in front of it, it will attempt to stab him with its tail, spanning the length of the arena.
If Bomberman is to any of its side, it will shoot beams of electricity up, down, left and right from its middle.
If its door is closed, its only attack is to swallow a bomb directly in front of its door; Bomberman will be harmed if he is standing in range of this animation.

The boss can only be harmed when its door is open, during which time it is vulnerable to bomb attacks from any direction. After 4 hits, its electricity attack will now shoot in 8 directions, covering more area with diagonal beams as well.
Requires 7 hits to defeat. 15000 points.

Grey Mechanica World / グレーメカニカせい (Mech World)

This world features press machines; 2x2 tiles that are periodically flattened after 6 seconds by a weight from above, detonating any bombs and killing any enemies placed on them.

Stage 8-10 (boss)

A retread of the World 5 boss, but now it's got two hammers!
The hammer strike covers approximately 7x5 tiles.
Its boomerang attack throws both hammers at once in opposite directions, covering a wider area and negating the safe spot in front of the boss.
Requires 10 hits to defeat. 20000 points.

Blue Tune World / ブルーチューンせい (Future World)

This world features conveyor belts; it will slowly carry objects in the direction they are moving.

Stage 9-10 (boss)

Skeleguard will move left and right, trying to remain above Bomberman at all times.
If it pauses, it will charge forward, erasing any bombs in its path before returning to its starting position, laying 6 bombs vertically in front with a 2-tile blast radius.
If it flexes its claws, its claws will thrust forward to the bottom of the arena, before shooting a stream of fire from the skull that will turn left or right towards Bomberman's current position. Standing close but off-centre to the skull will prevent it from targetting Bomberman.

The boss cannot attack you if you stand directly to its left or right; equipping at least one Speed Up will allow you to lay a bomb on the far wall and lure it towards it, and give you enough time to avoid its attacks and repeat on the opposite wall.
Requires 10 hits to defeat. 20000 points.

Bagular's Spaceship / バグラーせんかん

This world features magnetic poles; they activate every 7 seconds, and for 3 seconds will draw bombs within 3 tiles of their position towards them.

Stage 10-10 (boss)

Bomber Robo is a four-legged walker that takes slow steps towards Bomberman, moving two legs at a time, often laying bombs when it lifts each leg. Bomberman cannot walk through the legs, and will be harmed if he is stepped on.
If Bomberman is below the boss, it might raise its front legs and slam them both on his current position, placing two bombs with a 2-tile blast radius in the process.
When its legs are evenly placed, it might lower its body and deploy a roaming missile, which tracks Bomberman -- it has minimal evasive properties, and will happily wedge itself against a bomb if Bomberman is on the other side of it.

The boss can only be harmed when its body is lowered. Its movement speed will subtly increase after every hit, and its bomb blast radius will increase by 1 tile.
Requires 10 hits to defeat. 30000 points.
