Normal forme is probably the worst. Huge attack, but squishy as **** , and less attack than Attack Forme, and you might as well go all-out with attack forme.
Defense form is pretty good for setups and stuff. If you invest into the HP it's not a bad tank, and pretty fast for a tank too.
Speed forme... well it has more balanced offense/defense, and it is literally the fastest pokemon that exists, but that much speed is almost entirely unnecessary.
I really loved the delta episode, because remember the original RSE? There was ALWAYS an urban legend that if you did something ("something" changes depending on who's telling it) you get to go to space and catch Deoxys.
this little asshat caught me off guard. i managed to quickball rayquaza and expected to happily go on my way, but no. the previously event exclusive asshole showed up at lvl 80 and nearly wrecked my face. had i not had my metagross with me i wouldnt have made it to the last greatball that he finally gave up in.
