I could not attack, neither did I pass a turn, nothing and I don’t know if it is a bug or hack
You got a monster from a hacker. This is a special form of Maggatsuoh, which (spoiler warning) you will find as the true final boss of the main Story Mode, as of now.
It’s clear it’s a hack from two things:
- the sheer size of the sprite
- the MonsterDex number (there are currently ~1900 registered monsters)
The guy is also rank 38 lol
It’s a pure hack
