Koopatrol are Koopas in spiky, metal armor. They are the Elite soldiers of Bowser's army and are found in the Paper Mario games. In Paper Mario, Goombario's description of them is: "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." In Paper Mario: The Thousand-Year Door, Goombella says of them: "That's a Koopatrol. A Koopa Troopa who protects himself with spiked armor. Max HP is 6, Attack is 4 and Defense is 2. 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?" Tippi from Super Paper Mario gives us this tidbit of information: "That's a Koopatrol, a merciless minion wrapped in spikes and armor... You better not try to stomp on it... Koopatrols tend to rush in and tackle, so watch out... Only the toughest Koopas are selected to join the elite Koopatrol guard... They have to sharpen those spikes every day. That's what it takes to be the best..."
