I was going through GTS trade and got a shiny Magnezone for my Level 92 Nagandel. It was shiny, so I got a bit suspicious, that it was being traded for something you can get in-game easily. Here are the stats and moves:
Magnezone @ Magnet (Pokérus)
Has a relaxed nature, and sturdy body, and Analytic ability.
"Seems to have traveled across time and space to reach you from the Kanto region."
Flash Cannon /Thunderbolt / Magnet Rise / Volt Switch
289 Sp. Atk / 262 HP / 192 Atk / 291 Def / 227 Sp. Def / 143 Spd.
The only reason I think it's hacked is that shiny + HA + Pokérus + level 100 and that I think it's not possible for a Pokémon bred in Kanto to have a Hidden Ability because they were introduced Generation V. If they used a Virtual Console and transferred it over then it would make more sense, but shiny Pokémon were introduced Generation II, so transferring a Kanto Pokémon, and having it be shiny and HA is very lucky.. Pokérus was also introduced later, also in Gen II. It could be pure luck, but I don't think it just matches up. The player I traded with- I can't paste their name or anything, and it seems they're Japanese, Korean, or Chinese, because of the name of the Pokémon and their own name. (I can't read any of the languages stated above, so I get them mixed up)
Does anyone think this is a hacked Pokémon- or just a lucky trainer?
