Well, Yveltal's confirmed to be part dark-type, so you could be right about it representing death (and Xernias representing life).
It is the Destruction Pokémon, and destruction is usually associated with death, isn't it?
Meanwhile,
Xerneas is the Life Pokémon. Wonder if it knows Arceus?
... Although for some reason I almost thought Xerneas was related to Keldeo, Cobalion, Terrakion and Virizion.
What do you think of Dragon Ball Z?
Have you ever seen Dragon Ball Evolution?
- It's pretty cool.
- Sadly, I haven't.
If you could summon any one starter Pokemon in real life, what would it be?
It would be Pikachu.
EDIT:
I have 100 more questions to answer - those 100 belong to Wayne.
It'll take some time to answer, of course.
