Echovirus (short for Enteric Cytopathic Human Orphan Virus) is one of the leading viral causes of meningitis. I think that this pathogenic would be an interesting, challenging, and overall great boss for the Brain.
Phase 1:
The player enters the boss arena to see the virus attached to the wall (in this case, the meninges). The virus rotates around the wall slowly and shoots cascades of bullets that inflict a burning effect similar to pyrosome, as a nod to the inflammatory effects of the virus in real life.
Phase 2: the walls of the meninges slowly shrink towards the player at a fixed amount and the echovirus' movement circling the wall becomes faster. Touching the walls will deal damage and cause a burning effect to the player.
Phase 3: The walls shrink slightly one last time, and the Echovirus begins to copy attacks of the player to use against them, a nod to the name "Echovirus". The virus is at its fastest when traversing the meningeal wall during this stage.
Upon killing the virus, it bursts into flames and the meninges go back to their normal size.
If anyone would like concept art of this or a more in depth explanation, I would be happy to provide it!
