Mega Altaria may be arguably one of the most adorable Mega Evolutions in Pokmon GO, but it can make for a demanding boss you’ll need to target its weaknesses with a strong team of counters to win. Along with a decent CP (Combat Power), this fluffy dragon also comes with a strong balance of Attack and Defense. This means this enhanced form of the Swablu evolution can give out just about as much damage as it can take, adding a bit of danger to its tank-like combat ability.
