Army Hammer Bro.

"To reach my Lord's castle, you must chew off my body first. But that's not gonna happen, pal!"

Army Hammer Bro. is a boss character who appears in the Prismverse Saga. So far, he only appears in SMATSP, as a mini-boss in Volcanic Lavalands.

History
Army Hammer Bro. only appears in Super Princess Peach, as Bowser's right hand minion. He is the one who finds the Vibe Scepter, and then captures Mario Bros. and the Toads, forcing Peach to take up the task and face Bowser. He's fought right before Bowser at the final level, empowered by the vibe scepter. But he's defeated at the end by Peach.

In Prismverse Saga
Army Hammer Bro appears as a mini-boss fought in the level Aeronautical Koopa Armada, leading a flock of various elite Koopas (like Hammer Bros) to take down Mario Bros. Despite of his efforts, he's defeated by the heroes, and knocked out. He's seen in the credits, severely injured from the encounter.

His future appearances are unknown.

 * This theme is shared by various other minibosses.

Lore
When it comes to Koopa Troop, there are many ranks of the said clan, ranging from the weak Goombas, to the high-rank enemies, like Hammer Bros. One of these, in fact, had caught the attention of the King of the Koopas himself.

This specific Hammer Bro, unlike his other comrades, was merciless and vicious. He had the determination that others wouldn't even have when they all gather around to oppose him. Bowser got the twinkle in his eyes, a twinkle of ambition and strength. These great attributes of his had made him climb up many ranks in the clan, eventually reaching the spot into one of the best elite minions of Koopa Troop that was ever seen.

Unlike his brethren, he's capable of throwing even bigger hammers, and can call other Koopa Troop to his assistance. He's a great force to be reckoned with, a force that almost managed to end the legacy of Mario Bros. once before, only to be defeated by Princess Peach.
