Koopatrol

Making their debut in Paper Mario, Koopatrols are elite soldiers of Bowser's Army. These guys are high-ranking guards of Bowser's Castle. Most Koopa Troopas dream of becoming Koopatrols. They have physique similar to Koopa Troopas, but they wear intimidating spiky armor.

These guys are found in Bowser's Castle in Paper Mario, they were shown patrolling Bowser's and Princess Peach's Castles after Bowser stole the castle and uprooted it into the stratosphere.

They are later found in Rogueport Sewers in Paper Mario: The Thousand-Year Door after Mario and his team clear Chapter 5. And there are also an advanced type of Koopatrol, the Dark Koopatrol, only it has red eyes and blue armor.

Paper Mario Stats
Max HP: 8, Attack Power: 4, Defense Power: 3

Tattle: This is a Koopatrol. They're elite Koopa soldiers. These are the highest-ranked guards of Bowser's Castle. In case you hadn't noticed, they're fitted with spikes. Don't jump on 'em. When their HP drops low, they'll charge up power for one last-ditch attack. The power of this desperate attack is 10. They've also been known to call in reinforcements when they're in trouble. Don't underestimate these nasty Koopas, Mario.

Regular Koopatrol
HP: 6, Attack: 4, Defense: 2

Goombella's Tattle: That's a Koopatrol. A Koopa Troopa who protects himself with spiked armor. It attacks with its shell and with its head, then sometimes charges up for a fierce move. Plus, if you take to long to win, it'll call in reinforcements. Yeah, sorta gnarly, huh? It's one of the worst of Bowser's guys. Koopa Troopas dream of being Koopatrols. ...Hey, and by the way, what do you think Bowser's doing now, anyway? Eating?

Dark Koopatrol
HP: 25, Attack: 5, Defense: 2

Goombella's Tattle: That's a Dark Koopatrol. These guys just totally ooze toughness, don'tcha think? After it charges up power, its next attack will be devastating. Try to survive it. It's almost like those red eyes are there to warn you just how tough it is... Or maybe it just doesn't get much sleep...
