Cosmo

Description
Cosmo is a powerful spirit and ex-resident of The Citadel. She ran away through the House in an attempt to run away from the Citadel; escaping into The Forest. She was kept around as a ghost after her death at the hands of Infinite when her universe's Amy promised her that 'we'll see eachother again'. Since Amy was killed and not in The Citadel, Cosmo was unintentionally granted immortality. She has also mentioned a four year period where Infinite did some 'even worse shit' than he was already doing. This has so far not been elaborated on.

Ghost Physiology
As a ghost, Cosmo is immortal, can fly, is intangible and can interact with other ghosts.

Agrokinesis
Cosmo has the ability to manipulate plant life, bending tree branches and growing unnatural plants. So far she hasn't really gotten to use her powers outside of that, but she is said to be very adept in this.

Her Amy
Cosmo was in a romantic relationship with the Amy from her universe, and is still not over her death after four years.

Naka
Naka was the one who convinced Cosmo to come to the House after telling her about Rocket, a Bondswap Tails. She prefers to be around Naka, as he doesn't call himself 'Sonic'. Futhermore she said she met a version of Naka in the Citadel, and he was nice to her.

Ashura
Cosmo thinks Ashura is kinda neat.
