'''BlassCFB''' is a former Argentine player who specialised in straight-flying. He was known for creating and verifying his Hatred-difficulty, timing-based level WcropoliX, which was Top-1 difficulty at the time of its verification but was not rated until over eight years later. He is also well-known for being the second victor of [[Sonic Wave]], and the third victor of [[Yatagarasu]]. He currently has over 70,000 subscribers on his YouTube channel.

==History==
BlassCFB created his YouTube channel on 30 August 2015 and beat Deadlocked on the same day.<ref>https://www.youtube.com/watch?v=SirFgjy_Jbs</ref> He then started beating some Easy Demons, such as Wrandering,<ref>https://www.youtube.com/watch?v=sL-o2KFEUsU</ref> The Magma Caverns,<ref>https://www.youtube.com/watch?v=V5wKGtDkVPA</ref> Dark Hell,<ref>https://www.youtube.com/watch?v=lZyf29dEIvw</ref> and The Dragons Lair by NuclearNacho6.<ref>https://www.youtube.com/watch?v=dRS0dLj5LBk</ref> His first major Demon completion was of Theory of SkriLLex, in which he crashed at 98% before beating it on 26 September.<ref>https://www.youtube.com/watch?v=GEfIjsVOtaI</ref>

After many more Demon completions, he beat the unrated Insane 9* difficulty level Wcropolis on 23 October 2015 (a level which would later inspire Blass to create a superbuffed remake of the level named WcropoliX).

He then started beating Insane Demons and went on to beat [[Supersonic]] on 27 December 2015,<ref>https://www.youtube.com/watch?v=oUqcnckmISY</ref> [[Windy Landscape]] on 29 December,<ref>https://www.youtube.com/watch?v=Qdhr-hvirJ0</ref> [[Acropolis]] on 3 January 2016,<ref>https://www.youtube.com/watch?v=9GCwsrZU_oM</ref> and [[8o]] on 5 January.<ref>https://www.youtube.com/watch?v=hjfziGzSgLA</ref>

Following a few easier Demon completions, he beat [[UltraSonic]] on 15 January 2016, Cursed Mansion on 14 February<ref>https://www.youtube.com/watch?v=i4YLKZlT-Lo</ref> (a rated Insane Demon remake of Acropolis), and El Dorado on 29 February.<ref>https://www.youtube.com/watch?v=FT5_b_qISCw</ref>

On 8 March 2016, BlassCFB uploaded a video announcing that he would beat the old version of [[Cataclysm]].<ref>https://www.youtube.com/watch?v=_GvU8H_IW3Q</ref> He uploaded a progress video of 64% on 11 March,<ref>https://www.youtube.com/watch?v=SKzkwfjhKb0</ref> and a video of 71% the following day.<ref>https://www.youtube.com/watch?v=0eP_j-ll-gA</ref> On 13 March, he beat Old Cataclysm after 13,795 attempts,<ref>https://www.youtube.com/watch?v=cpA9hlEr_J4</ref> making it his hardest completion at the time.

After beating Landect on 25 March,<ref>https://www.youtube.com/watch?v=OSgyvMt7ekw</ref> he announced on 29 March that he would beat [[The Ultimate Phase]].<ref>https://www.youtube.com/watch?v=CFkfL9rFOxU</ref> Following several easier level completions, he uploaded a progress video of 78% on The Ultimate Phase on 1 April. He would go on to beat the level on 4 April,<ref>https://www.youtube.com/watch?v=FeiZUlpPTVg</ref> after 9,966 attempts.

On 12 April 2016, he announced his new remake of Wcropolis, WcropoliX.<ref>https://www.youtube.com/watch?v=Anax7mAaom0</ref> It is superbuffed compared to the former and is of Extreme Demon difficulty. He beat Crimson Clutter on 22 April,<ref>https://www.youtube.com/watch?v=qpe7Mq9ygYo</ref> before completing a new hardest Demon, AcropoliX, on 5 May 2016,<ref>https://www.youtube.com/watch?v=kOHNaPiUmBo</ref> after 10,136 attempts and a fail at 98%.

On 31 March 2016, Blass uploaded the first video of a new series on his channel in which he would beat challenge levels made by fans that were named 'Blass Challenge'.<ref>https://www.youtube.com/watch?v=JYJjmm9dtkk</ref>

He announced on 1 June that he would beat the new buffed version of Cataclysm. He beat it the next day, making it his second-hardest Demon at the time.<ref>https://www.youtube.com/watch?v=9D2WzHmuHyU</ref>

He uploaded a final preview of WcropoliX on 20 June 2016.<ref>https://www.youtube.com/watch?v=GPglgejE5Zw</ref> It showed new decoration and design, along with further heavy buffs having been added, making the level Top 1 difficulty at the time.

On 22 June, he beat [[A Bizarre Phantasm]], making it his new hardest Demon.<ref>https://www.youtube.com/watch?v=VWFvj1EA-HE</ref> He continued beating Insane Demons, such as Leminscate, [[Necropolis]], and Ultraviolet, before he started working on verifying his new Extreme Demon, WcropoliX (which he had further buffed). On 25 July 2016, he achieved 77% on the level,<ref>https://www.youtube.com/watch?v=vTt0KIaPzWg</ref> and on 31 July, he verified it after 8,240 attempts,<ref>https://www.youtube.com/watch?v=pQ2PsY1BymE</ref> marking his hardest achievement at the time.

After beating more Insane Demons, such as Infrared,<ref>https://www.youtube.com/watch?v=vBD1YqmUNwQ</ref> Dark RainBow Rebirth,<ref>https://www.youtube.com/watch?v=H7Nt4tTYOGs</ref> and Galatic Fragility,<ref>https://www.youtube.com/watch?v=Kthaw_iHCyQ</ref> He started practicing [[Bloodbath]], the Top 1 hardest level according to the [[Demonlist (Pointercrate)|Demonlist]] at the time, achieving 94% on 20 August 2016,<ref>https://www.youtube.com/watch?v=o7wAd4Ec1hQ</ref> and completing it the next day after 8,345 attempts,<ref>https://www.youtube.com/watch?v=VU7UtX-Z4WQ</ref> making it his second hardest achievement at the time (as WcropoliX is generally considered to be harder).

On 7 May 2017, he announced that he would quit the game and stop any activities on [[Geometry Dash]].
