Titleinlarge, also known by his former YouTube account name Titleinlarge503, was a popular yet controversial Flash Pooper formerly well-known across the YouTube Poop community. Among being known for his creation of God Rabbit and for pioneering the concept of story-based poops, he is most infamous for his extremely controversial project titled Super Smash Bros. Dimension - a project which never finished (or possibly even began) production, instead being known for the sheer amount of backlash that it had garnered from the YouChew community.

Apparently, there was supposed to be a part four, but Titleinlarge eventually left before he ever finished it. However, the three main parts can still be seen reuploaded on YouTube.

Notably, before Titleinlarge had been able to finish part three of the God Rabbit saga, he announced that his special effects software had malfunctioned and stopped working, even as he tried to open the program again. The stress of this, combined with the mass removal of Dr. Rabbit-related videos by the Colgate-Palmolive Company, eventually led him to close his original Titleinlarge503 YouTube account. The user Meleemario720 was appointed to complete the rest of the third part, officially providing closure to the trilogy.
Super Smash Bros. Dimension and Subsequent Disappearance
After Titleinlarge was able to repair his software, he then began undertaking a project called Super Smash Bros. Dimension, a parody of the Super Smash Bros. series featuring primarily YouTube Poop characters. Titleinlarge would post updates regarding the project on his DeviantART account, and the project began amassing a fair share of fans.
However, as the YouChew community was disapproving of Flash Poops at the time as they did not view them to be "real" YouTube Poops, members began to insult Titleinlarge and mock him on the forums, being harshly critical of the project.
In May 2008, Titleinlarge suddenly disappeared by closing his YouTube account, removing all of his Deviations, and hiding all of the comments on his page. This is said to have been caused by Titleinlarge's depression, as the project was simply too ambitious and he couldn't stand the pressure of both developing the thing and receiving inflammatory comments. SkyBlueFox purports that his disappearance was a decision by his parents, as the amount of hate comments towards him had grown beyond control, necessitating action from his parents.
After some research done through Titleinlarge's FX.com account, "SavagedMarquise", it has been identified that he has had a total of four YouTube accounts throughout his entire YouTube experience. There is a possibility that he may have a new account on YouTube, but this remains unconfirmed.
