Those Pokemon are known as two of the strongest Psychic Pokemon around, but who's the better among the two?
-Who's the better battler?
-Whose design do you like?
-Which one is more useful?
-Which one of them do you like in general?
As for my answers:
Question 1: Deoxys (it has 4 formes, making it suited for attacking, defending or supporting)
Question 2: Deoxys (I like how it can turn its arm into strands of DNA)
Question 3: Deoxys (see answer to question 1)
Question 4: Deoxys (see above answers)
