The cosmic entity just short of being cannon
M87 originally appeared at the end of volume 1 (in this original version, season 2) as a dark silhouette floating in front of a balck hole, with the text "wake up." in the corner. You could see him fully in the picture by brightening your screen. This is connected to OG lore of 12 Orbs, which was that the computer and the adventures were all a dream, but in the end it was scrapped, and M87 now sits in the endless void of non-cannon hell to be remebered as an honorable easter egg in the early days of 12 Orbs.
Krabo has somehow managed to escape non-canon hell and has been surfing the multiverse ever since. Leaving M87 to rot in there, and he also sells chicken tenders and fries. In some of the (upcoming) non-canon bloopers he's seen selling chicken tenders to Robin, Batman's sidekick and leader of the Teen Titans. He is also the MDB (Multiverse Defense Bureau)'s most wanted person because of the chaos he "accidentally" caused in the universe of "Astro Bot". He is also an escapee of the Hadal Blacksite.
