At 155, Magnitogre has the highest HP of all Pokémon in the Sage Pokédex.
Magnitogre is based on Magnitogorsk 'Magnetic Mountain', a factory city in Russia from pre-war Stalinism.
The initial concept of Magnitogre was doodled by it's creator during one particularly engaging lesson on Russian history, including it's name. This initial doodle, however, consisted of a mountain with a horseshoe magnet stuck on top and lots of zig-zag magnetism lines.
Later designs depicted Magnitogre as having a human-like face comparable to Nosepass and Probopass. However ultimately a less anthropomorphic design path was taken.
Magnitogre's name is a combination of Magnitogorsk and ogre.
