Biolizard

From Sonic - Wiki on Neoseeker

Biolizard was a prototype created in the experiment to create the ultimate lifeform. It was developed aboard Space Colony ARK by scientists. Leading the project was Prof. Gerald Robotnik. In a cut-scene near the end of the Dark Story, Rouge prints off data from the ARK's computer, with a good eye, a player can notice that this sheet holds Biolizard's picture. On the print there is alot of clearly written writing which someone can freeze-frame.

Current Status

12:30A.M. on January 27th, we initiated the experiment to start Shadow's first prototype. The experiment was successful. The life form's eternal engine and the organ to start the Chaos control are working normally. However, the measurements of the experiment was higher than we expected, we will continue this experiment at the central dome from now on.

Note

Pr. Gerald pointed out that the growth speed of the prototype is getting faster. The current body length is 2.7m, and the current weight is 350kg. It's growing so fast in the last couple of days at an exponential level. Proffessional--

(subtitles obscure view)

We need to keep an eye on the prototype, because the prototype is still not strong enough to walk by itself but it has a strong neck and tail. The prototype is sensitive to the temperature and humidity changes and its intelligence and learining abil ity level is still low. At this point the prototype is still more like an animal.

EYES ONLY

Biolizard guarded the Emerald shrine which Sonic and Knuckles had to reach to stop the Eclipse Cannon. It was Shadow who fought his predecessor and defeated it to allow them access. However, Biolizard merged itself with the colony and began racing toward the planet as the Finalhazard. Sonic and Shadow used the Chaos Emeralds to become Super and defeated it.

[edit] Trivia

At an early stage in developement when only Sonic, Knuckles and Eggman were playable, Knuckles did battle with Biolizard in the original fight, how he would do this is still unknown.
Biolizard's panther-like roar is the same one used by Perfect Chaos and Devil Doom.
Biolizard is considered to be the most difficult Sonic series boss to date. He is considered unbarable in the Dreamcast version as there are several glitches that cause instant death, usually by falling into water while Shadow can't be controlled. These glitches are fixed in the Gamecube release as Shadow's falling path is set to land at several select points.
A trick can be performed whenever Biolizard uses his egg attack (even in zero-gravity, albeit much harder as one must stand at the absolute edge of the life support system) by charging a Light Speed Attack. Shadow will dash at random through several eggs, and, if done right, damage Biolizard with almost no effort. It seems this was put in on purpose, as the time before Biolizard fire the first egg is just long enough to charge the attack. Although it looks quite impressive, it is usually an avoided tactic as it isn't very safe and will fail if certain eggs are fired. To harm Biolizard using this tactic, one must stand close to his head or tail when they unleash the attack, otherwise they will simply destroy all the eggs on one side and have to wait through another attack cycle.
