Leopold the Cat (Mirror Dimension)

Leopold the Cat (Mirror Dimension) is Leopold’s mirror counterpart who appears in the Mirror World. His only appearance is in “Mitya in Mirror World”.

Appearance
Leopold’s mirror counterpart resembles his real counterpart, except that unlike his real counterpart, he doesn’t wear a bowtie and happens to wear biker boots instead of slippers.

Personality
Unlike his real counterpart, he’s a rude hooligan who seeks to cause trouble; he also happens to be a chain smoker.

While his real counterpart just wants to help others, Leopold’s mirror counterpart seeks to wreak havoc and has no problem pulling pranks on the mice.

In the fanfic
When Mitya gets separated from his friends and ends up in the Mirror World, he meets the mirror counterparts of his friends (plus his own mirror counterpart), they enlist him to help him defeat Leopold’s mirror counterpart; once he successfully does just that, they help him return to the real world, where he’s able to reunite with his friends.
