Doer

Doer the Cat is a non-planeswalker black cat that travels from plane to plane with his brother Michi. He has a complete disregard for the laws of planeswalking and physics in general. He wants to hunt the greatest prey he can find so he has a tendency to get into fights he can't win to become stronger.

First years
Doer and his brother Michi were born togheter, in the same litter. Doer was the first of eight brothers. They were raised in the streets of the plane. They were completely normal cats. Doer was the biggest of all their brothers. Doer was a great hunter and suprisingly stealthy for his size. He hunted for himself and for Michi.

Michi goes missing
One day Michi dissapeared and Doer had to track him to a wizard's house. The wizard wanted to kill Michi to perform a ritual to become immortal. Doer jumped and pushed the wizard into the spell, obliterating him. The magic explosion mutated Doer and Michi, giving them consciousness and igniting Michi's planeswalker spark.

Michi sparked to the plane of Ravnica. Doer was left in their home, alone, but he percieved Michi was somewhere out there and he broke reality in the same spot Michi had planeswallked from, appearing at his brother side.

Travelling
Doer and Michi spent some time in Ravnica. Doer tried to date Massacre Girl, fought Ruric Thar for the leadership of the Gruul and killed a Devkarin Lich.

After that, both brothers spent a time in Theros where they met Elspeth Tirel before she got killed by Heliod. Doer fought with Elspeth against the hydra Polukranos, but that got erased from history books. They travelled to the Underworld and Doer fought in one versus one with Erebos. He got defeated and Michi had to scape with him to avoid Doer getting killed.

Both brothers spent a big time in Balix, where Doer spent most of the time mocking the dwarf smith Jhoannes Jhon. He also hunted some monsters. Soon after, they planeswalked to The Arena.

The Arena
The first thing Doer did after arriving in the Arena was pick a fight with the phyrexian Khon Vasq.
