|Artwork of Grenade Man from Mega Man 8|
Using the impressive speed given by his overdrive system and a variety of explosives including his signature weapon, the Flash Bomb, this sadomasochist is a dangerous force that will shake up the battlefield and blow away the opposition.
Grenade Man is a big blue robot with a design inspired by the look of a MK 2 grenade (known alternatively as a Pineapple Grenade). His upper chest has a yellow frame with black diagonal lines indicating caution, with the rest of his torso being blue with the lower half featuring the segmented grenade design. His arms are grey with Yellow and red shoulders and primarily blue hard armor forearms featuring a few red details, with one arm ending in a fairly normal hand and the other featuring an arm cannon designed to shoot Flash Bombs and other explosives. The cannon has a yellow muzzle with red details and a green core inside. His legs are similar to his arms, having grey soft armor, yellow joints, and blue hard armor with red details. His feet are notably white with grey bottoms, and the cores on the sides of his feet are also green. His head is similar to Hard Man being somewhat cylindrical, with a circular flat top. His face is grey with his mouth covered by a knight-like mouth guard. His eyes are the color red, but oddly gentle. On top of his head and hanging over the back, he has a head ornament similar to a striker lever, being another element of his Grenade motif.
Grenade Man's movements are fast and sudden, doing long jumps, dashing relatively big distance at high speeds, and hanging on walls. When he is not directly throwing any bombs, he will use these techniques to collide with the Player Character or reach a better position to fire at them.
Grenade Man's main technique is firing the Flash Bomb, which will explode if it enters on contact with a target and will reflect any of the player's weapons fired at them excluding Thunder Claw and some Barrier Weapons that can hit them back at him. He may fire the bomb when standing on the floor or when hanging on a wall. When firing from the ground, Grenade Man will shoot directly forward in the direction he is facing, but if fired from the wall he will aim diagonally downward at wherever the Player Character currently is. After using the Flash Bomb from the ground, he can cause chunks of building debris to fall from the the ceiling and land on the Player. This will only happen if the Flash Bomb makes contact with a wall, and will not happen if the bomb is deflected back at Grenade Man or is set off by colliding with The Player Character. The debris cannot be destroyed by most weapons, with only some Barrier Weapons being able to deflect them or send them toward Grenade Man. The Black Hole Bomb can suck the debris.
The Flash Bomb produces the explosions after touching terrain, the player character, or Grenade Man. If the bomb is reflected to another target, the bomb will be despawned without the explosions. The explosions can be despawned with the Proto Shield.
He can fire other projectiles in addition to the Flash Bombs. He will sometimes jump off of walls with a wall kick, and when he does he will fire 3 small grenades down in front of him as he is moving, these small grenades will lightly bounce off the floor before exploding. After receiving enough damage, he will fire out a set of 4 detonating bombs that do not harm upon contact, but will soon after landing cause a series of explosions across the ground which will require the Player to precisely jump over them just as they explode if they cannot otherwise get out of their range or deflect the bombs when they are fired. This attack in Mega Man 8 served to change the layout of the arena by destroying the floor and forcing the Player into a lower room, but the attack was simplified due to the limitations of a level builder.
- Because Grenade Man comes from the 32-bit game Mega Man 8, he lacks official 8-bit sprites. As such, the sprites featured in Mega Man Maker were custom made for the game by Zedicon.
- Grenade Man has a custom entrance animation. Rather than descending from the sky, Grenade Man will enter via a large explosion in the wall. After which he will give a thumbs up.
- The weapon Thunder Claw has the ability to reflect Grenade Man's Flash Bombs, this is because the weapon was his original weakness in Mega Man 8 and possessed the ability to do so in that game.
- In Mega Man 8, one of Grenade Man's battle quotes was "Say hello to my cute bombs!". This is believed to be a reference to the movie Scarface as it is similar to the line "Say hello to my little friend!"
- Although Grenade Man doesn't speak in Mega Man Maker, this referential quote was itself referenced with the flavor text for the Grenade Ladder where it says "Say Hello To My Cute Ladders!"
- Oddly, Flash Bombs fired downward by Grenade Man don't cause debris to fall when they explode upon hitting the floor. This is accurate to the original game, but strange none the less.
- If Grenade Man is fought in a room that lacks walls, he can still jump up to the sides and stick to them to shoot down or wall kick. This is even in rooms that have others to their sides and are still just open space. This may have been left in intentionally to avoid limiting some of his moves, though this has not been confirmed.
- If Grenade Man is fought in a room that is located at one of the top most screens of the map, the game will crash if Grenade Man uses his horizontal Flash bomb attack and causes debris to fall. This may be the result of some of the debris attempting to spawn in an above room that doesn't exist as even empty space.
