Lvl25 lugia in my pokemon emerald?!?

Question

today i bought a used pokemon emerald game. when i played it, the previous owners' account was still on there so i decided to check it out. i checked the person's party and i find a lvl35 lugia(met at lvl25, route 116). so i go online and it says that the only time you can get lugia in emerald is when it's at lvl70. any possible ways that the previous owner got it?

Answer 1

wait how can u only get a lvl 70 lugia
