Rock Troll

The Rock Troll is an Emblem Heartless that appears in Kingdom Hearts III. It can appear as either a boss or a common enemy depending on the fight.

Design
The Rock Troll is a gargantuan, brutish Heartless which wields a large axe. Its body is purple and covered in armor, with an opening in the middle where its head sticks out, surrounded by chains attached to the armor. It has a jagged yellow mask covering its lower face, with the rest of its face darkened. Above its yellow eyes is a purple helmet where its Heartless emblem is placed. Above its head is the top of its body, surrounded by two massive dark shoulder plates which feature golden hexagonal outer plates and a massive cracked horn on each. On each of its arms is a jagged purple plate of armor with a chain wrapped around it. Its legs are smaller than its body, and have two plates of armor above its golden feet.

The massive axe it wields has a golden handle with a purple Heartless face in its center and blocky blades on each side.

Strategy
The Rock Troll is first found as a boss in Olympus. It will start his attack by slamming its axe in the ground, creating a rocky shockwave. This will break Sora's guard if blocked, and can allow the use of Risk Dodge if playing on Critical Mode. The Pirate Ship Attraction is useable during this fight and can make defeating him a lot easier. It can be defeated without its use, however. Its other three attacks are a brutal double axe slash (second slash triggers Risk Dodge on Critical), a rock spin which deals minimal damage and can be blocked, and a quick punch with his left arm that can be blocked. Sora should be stocked with Potions to support himself and his allies. Its reaction value doesn't decrease if anything other than its face is attacked.

Every 50 seconds, the Rock Troll can turn its axe into a mask and vice versa, although it will not use this technique in Olympus and the Keyblade Graveyard. When used, its attack pattern will change (see the attack table below), it will gain 100 armor value, and it can move around while using Trample.

Its attacks are telegraphed by its movements. If it walks around or roars for no reason, it won't attack. If it jumps backward, it will use its shockwave axe attack. If it turns around, it will use its double slash attack. If it plants its axe in the ground, it will use its rock spin attack. This troll only has about 3.75 HP bars, so as long as Sora blocks all his attacks, heals himself and his allies with potions if necessary, and makes good use of Team Attacks and Attractions, the boss should fall with ease. Upon defeat, Sora will gain a max HP increase.

Another Rock Troll appears as an early boss in Arendelle, flanked by Winterhorns. The strategy is the same, but this troll is much stronger, has much more HP (about 8.5 bars), and can access an armored mode, of which it has three attacks: it can spit large rocks which can deal heavy damage, slam into Sora to deal heavier damage, and its old left arm quick punch. Its slam triggers Risk Dodge on Critical, but on other modes it is better to simply dodge away from the charge. Upon defeating the boss, Sora will learn Groundbreaker.

Rock Trolls appear as common enemies during the initial fight upon visiting the Keyblade Graveyard.
