Articuno?
You Don't, That's only in Pokemon Gold, Silver & Crystal. Red is one of the name choices for your character when starting a new game.

Well, you should probably name him something like Gold or Heart, because that's the rival version of Soulsilver. Hope I helped!!
Your rival is named Rival and he's the same rival from Gold, Silver, and Crystal version. His official name however is Silver.

There isn't a Pokemon Chronicles episode that Gold meets silver and Gold's real name is actually Jimmy in the show, but I don't know Silver's name.

Think about the pokemon's type and appearance, that helps me decide a nickname for my pokemon. Blaziken is a bird so maybe something bird related with its type like Flamebird or Blazebird.
