Mark's second YouTube channel was originally a shitpost channel called 'LoSer Mark', but he later re-branded it to SplashDash where he makes videos discussing Sonic The Hedgehog. Mark has done many of these videos, starting with his video talking about his love for the Diary of a Wimpy Kid trilogy. These videos on LS Mark's channel focus on movie franchises, usually only going for 2 to 4 movies. In the February of 2021, he relisted his old commentary videos to show the progression of his channel. Mark's last commentary video was 'Game Grumps is on it's last legs'. However, due to too much negativity in the community, Mark decided to stop making commentary videos and privatized as well as unlisted his old videos and started reviewing animated media, movies, and video games. He quickly became a commentator, presumably due to this newfound viewership.

It quickly spiked in popularity, currently sitting at almost 300,000 views. On March 26, 2018, Mark uploaded a video on Butch Hartman. Mark's old sonic videos are now unlisted, but some users saved nearly all of the old LS Mark videos, In 2020, he made a second channel called 'SplashDash' for making Sonic videos. Mark continued making reviews and eventually began to make commentary on the Sonic games.

Mark then went on to doing drawing and pixel art tutorials, the channel was renamed as 'LS Mark' sometime around 2015, (He still uses his older channel name ImmortalResurrection in the link) Mark would produce his first 'commentary' video when he uploaded his review for Sonic The Hedgehog. His earliest accessible uploads were a series of gaming videos, where he played the mobile port of Sonic The Hedgehog 1 for the Sega Genesis/Mega Drive, which would later be unlisted somewhere around 2018. Mark started his channel at the age of 12 as 'Immortal Resurrection' in 2014.
