All of the Main Protagonists in their transformed states. For anyone wondering, these character's are from their own stories in their own individual universe. They do all share a link as they are in a multiverse. The only two that share a universe are the middle and middle right characters.
This is the big bad multiversal threat for the finale of the series. His presence can negatively effect any universe, and ultimately erase them entirely. His duty is executed by his cult, who seek to gather energy from the erased universes to one day bring their lord back from the void and cleanse all of existence.
The lore behind this picture is that this Capybara inherited godlike powers. The story goes like this, Heaven made a gorilla their champion and bestowed upon him the power of god. Satan became envious, so he decided to make his own champion. The devil gave his power to a Capybara, but this Capybara was a devout buddhist and was so unbelievably zen and carefree that he just kind of purged the evil out of the devil's powers.
If you read the lore above, you'll probably suspect this to be the god powered gorilla in question. I originally made this character to one up the other strongest character, but decided to make a whole other universe for him and other godlike beings, such as the Capybara.
These are drifters. The title of drifter is what links all of these character's, it's that they have no universe to call home and are therefore not bound to a single universe, meaning they wander the multiverse unrestrained. Everyone except for Ignatus had to see their universe be erased by the cult, but Ignatus would see other's universes wither and disappear, saving as many as they could before the universes vanished for ever.
Syndilor woke up to see his universe was no longer there. Doc's world was lost to time and his universe crumbled due to an entropy plague. Gavel is a space viking who indirectly assisted in his own universe's erasure, and seeks to atone by carrying on the memory of what he lost. Medris lost her universe in a bloody war against the cult, and only survived because Ignatus saved her, but the trauma drove her mad, and now she acts the entropy cults boogeyman.
