From Quiz Elementary Pokémon Part 3
Answer:
Beautifly
The third generation Pokémon games designed for Game Boy Advance included "Pokémon Ruby", "Pokémon Sapphire", "Pokémon Leaf Green"; "Pokémon Fire Red" and "Pokémon Emerald". In the "Ruby", "Sapphire" or "Emerald" version you start with a Treecko (grass Pokémon), Torchic (fire Pokémon) or Mudkip (water Pokémon). On route you may encounter other Pokémon and try to catch them.
Be is beryllium. Au is the symbol for gold. Titanium is abrreviated Ti. Flerovium, one of the newest discovered unstable elements, has the symbol Fl. Y stands for yttrium. Put these symbols together and you get Be-Au-Ti-Fl-Y, the Beautifly.
The Beautifly is one of the final evolutions of a Wurmple. At level 7 the Wurmple evolves either to a Silcoon or a Cascoon, and at level 10 the Silcoon evolves to a Beautifly. The graphic appearance of a Beautifly is a butterfly with many colours and it is attracted to blooming flowers. Don't anger them, for the Beautifly has a strong special attack. The Beautifly is a Bug/Flying type Pokémon, and as such has extra strong attacks against a Grass type Pokémon. So if you use a Treecko and you would stumble upon a Beautifly, you better flee.
There are both male and female Beautiflies, so when you want to use a Beautifly to breed, pay attention to its gender.
