This is Iblis for ANY PERSONS continuity
Iblis (イブリースIburīsu?) was an immortal monster of mass destruction and was Silver the Hedgehog's main enemy in Sonic the Hedgehog. He was a creature who was born from "The Flames of Disaster", and takes the name "Disaster" from this. Iblis apppears to be mindless creature who only seems to be interested in causing destruction. His primary form has four arms and was a lava-like version of Perfect Chaos in appearance.
Sonic the Hedgehog 2.0Edit
Iblis first appears in book/movie 6: A Trip To The Future. He is seen when Sonic and co. were about to fight him. During the fight, Iblis tried to crush Silver, but Sonic as I-cycle shoved Silver out of the way, allowing Iblis to kill him. Soon, the shards of I-cycle re-formed into Waterdropp, and he (along with Sliver) used the Final Color Blaster to destroy Iblis (movie version only), but his minions remain. They went back to the present wanting to take over the Earth. Sonic and his teammates went to the present as well, and sang "Lead Me" and "Who am I?" to destroy the minions. However, in the movie version, After Sonic sings "Lead Me", Shadow sing "Gravity Hurts" from the BIONICLE saga. In book/movie 9: The Final Battle, Mephiles the Dark made Iblis return to life, and merged with him, and the Nega-Wisps to become Nega-Solaris. He was destroyed by Super Shadic.
Domestic Radical Adventures ForeverEdit
In DRAF, Iblis was mentioned in "Iblis the terror, Silver the deadly!". When Silver was attacking Sonic at the Terracotta Town Contest, Iblis appeared to appear in a very unusual way. It was found that Louis was the "Real Iblis Trigger" When Louis was in Cotonaava City (now known as Crisis City), an Ice Wizard (Wizard 101) made the city freeze then Louis fought the monster with a monster known as "Iblis". So the act of what happened to be "Evil" to Silver was to really save the city.
Iblis was the major boss and the optional Nanoimal as the pup when defeating Domino has Iblis.
