I'm hoping it has another ability related to Ice type pokemon. Also yes it does seem to be very defensive.
Yeah I'm hoping it gets an alternate ability alongside Own Tempo, hopefully something like Ice Body or Snow Cloak since those abilities are quite common on Ice-types. As for moves I'm hoping it learns, Icicle Crash is definitely one I want to see, because it's fitting for it considering it's based on a literal piece of ice, and hey it looks like a miniature iceberg.
I'm hoping its evolution turns out epic, I'd love to see how awesome an iceberg monster would look!
"The thing I wanted to share earlier: there is a random person from Hoenn talking about his region. He said it's a nice region etc etc, but the final thing he said was very interesting:
"You will see it in due time"
... k.
LOL it looks like he foreshadowed Ruby & Sapphire remakes! I knew it, especially giving all the "Hoenn Confirmed" jokes I saw floating around on the internet. But yeah, I have to say interesting piece of information there.
