Iblis is a boss encountered in Sonic the Hedgehog (2006). It is fought in all three storylines of the game, where Sonic the Hedgehog and Shadow the Hedgehog fight Iblis' second form, while Silver the Hedgehog fights its first and third form.
After shattering the Flame of Disaster's core inside Flame Core, Silver and Blaze confronted Iblis, who was getting closer to its final form, again. After beating it, Blaze sacrificed herself to seal Iblis away in another dimension.
Iblis Phase 1
When the battle begins, the player must collect Rings and fast. There are four lines of Rings in the arena: two in the air near the center of the platform and two on the extreme edges. While getting the Rings, the player must use their PK to pick up the nearby debris and start hurling it at Iblis. The monster has a significant amount of armor made out of cooled molten earth. However, the armor falls away as repeated attacks are launched on Iblis, exposing its pure ﬂame interior. To make an accurate volley, Silver must be pointed directly at Iblis in order to ﬂing the debris at the beast. Iblis will raise its arms from time to time, blocking his face. When Iblis is guarding itself, the player must not waste time throwing any debris at it. The player must watch for when Iblis raises all four arms. As when Iblis exposes its chest, a torrent of molten rock explodes forth, peppering the platform. Some of the ﬁreballs actually remain on the ledge, though, which can be picked up with PK and ﬂing back at the beast. When Iblis lowers its upper arms into the lava, Iblis will pick up a skyscraper. The monster raises the building high above the platform before bringing it down, casting a large shadow. The player must then get out of the shadow to escape damage. The smashed building leaves behind debris that the player can use against Iblis. After much of Iblis's Health Gauge is depleted, the monster resorts to breathing ﬁre on the platform. The sweeping ﬁre attack cannot be deﬂected in any way, so head for the sides of the platform to avoid getting burned to a crisp. After that, the player must keep hurling debris at the titanic Iblis to bring it down.

Iblis Phase 2
When the battle begins, the player has a few seconds to seek out Rings on the stone platforms in the lava. (The platforms are really fallen stalactites that were shaken loose from the lava dome’s ceiling.) Firstly, the player must collect some of the Rings for safety, but also leave some behind as a back-up supply should they get a damage. After the ﬁrst volley of ﬁeballs, Iblis sinks into the lava for a short time and then makes a large leap toward the player's location. So, the player must run away from the area of his impact or Sonic/Shadow will be damaged along the collapsed footholds. After that, he will bring down a batch of stalactites which creates a make-shift bridge to the three Purple orbs in the center of the chamber. When this happens, the player must make haste to the orbs, and avoid giving Iblis another opportunity to ﬂing more ﬁreballs at them. Then, the player should land a Homing Attack to slam into an orb and make it light up. The illumination stemming from the activated orb attracts Iblis, and the monster clumsily lunges for the orb with its pincers. If the player stands underneath the orb when Iblis arrives, they will be knocked off the platform. Therefore, after lighting the orb, the player should jump back one row of platforms to give the brute ample clearance to investigate the orb. When the worm’s forehead eye opens up, jump forward and use a Homing Attack. If this is done correctly, this attack should result in a loss of one-quarter of the monster’s health, and launch Sonic/Shadow back to the chamber’s far side, near where they started. If any Rings have been lost during the attack, pick up some replacements now. Iblis drops more stalactites into the lava after dealing the damage that was dealt to him, but these do not create a path to the orbs. These break the existing bridges. Jump back and forth around the remaining platforms to avoid the incoming blasts. Note that Iblis never creates the same path to the orbs, and sometimes only speciﬁc orbs will be available, such as the central one's. So, the player must use the available path to them in order to do damage to him, and through the same way. When Iblis has only a quarter of its health remaining, it changes its tactics. After lighting one of the orbs, the worm sinks into the lava, swims behind the platforms, and surfaces under the platforms. When Iblis surfaces, the player must use a Homing Attack to zero in on its green eye one last time, ending the battle.
If the player wants to earn a "S" Rank in this boss battle, they should do the following: Gather up some Rings and jump into the lava. Head to one of the orbs on the solid footholds and activate it during each time Iblis tries to sink into the lava. When Iblis is about to slam the activated orb, jump back off the orb quickly and do a Homing Attack at Iblis right after he has collided with the orb.

Iblis Phase 3
When the battle begins, Iblis raises his arms to issue forth his initial salvo of ﬁreballs. Silver’s platform is long enough to run to either extreme and avoid the volleys. The player should pick up Rings as they move. Several cooling balls of lava are sitting on the platform so the player can lift with PK and hurl them across the molten ocean to chip away at Iblis’s armor. After the ﬁrst batch of cooling balls has been exhausted, the player must wait out Iblis’s ﬁreball attacks to gather some projectiles to throw. Iblis's fireballs do not last for a long time, unlike their cooling variant, so the player has to use them as soon as they get them. If Iblis is building up an attack, do not throw at him as this raises the risk of hitting only one of Iblis’s projectiles instead of the lava leviathan itself. After he withstands several of the attacks launched at him, Iblis moves in for the kill. While he is approaching the foothold, Iblis will unleash a series of shockwaves that speed across the lava toward Silver’s platform. The player can either jump over or duck under the shockwaves as they roll into range. If the player is struck by a shockwave, they will lose Rings, and there is a good chance the ripple will wash them right off the platform. After reaching the foothold, the living ﬂame will slam its arms down on the platform, shattering the edges and making it smaller. The player can avoid the shockwaves made by this impact by Levitating as high as possible over the foothold. When it lowers its head, the player can spy its weak spot: the green eye in the middle of its forehead. A PK mark appears on the eye, signaling that it is now the chance to attack. When this happens, the player should Levitate over to Iblis’s head and stand on the marker, and then unleash a blast of PK to damage the living ﬂame, forcing it to recoil back across the sea of lava. While he is falling back, several cooling fireballs rise to the foothold which can be used to attack him more. After having half of his Health Gauge depleted, Iblis will raise his arms and conjures up a massive lava sphere. The player will have just a few seconds to watch Iblis gather up the lava before it catapults the sphere across the foothold. When the lava sphere is almost upon the foothold, use PK to take control of it, just like a normal ﬁreball. Still facing Iblis, throw the sphere back to deal damage to him. If the player misses the sphere as it descends on the platform, the sphere will destroy a great part of the foothold and cause damage to Silver.
If the player has not managed to defeat Iblis after the lava sphere attack yet, he will go into approaching the foothold in order to break another part of it again. The Shockwaves that he sends during his approach are more and at a faster rate this time. But, other than that, the rest of the fight works the same as before.
