Gen V

A new beginning.
Not just did they chose a completely remote and unrelated region for this generation, but even the legends don't seem to fit anywhere in the old picture.


First the elemental trio has returned.
And it has just a minor type modification to the previous (golems), similar to how ater replaced Ice for generation II. Now, Rock and Steel were used a second time, but Ice replaced by something fresh: Grass.
(an interesting note, they share the exact heights with the legendary beasts)
The legendary musketeers.
/
Cobalion, Terrakion, Virizion


Similar to Regigigas, they have a fourth member.
The apprentice.
/
Keldeo.
(Perhaps the next 2 trios will also have apprentices instead of guardians?)



Then there is the most contrasting mascots ever. They are black and white, Yin and Yang, Truth and Ideals.
The legendary dragons of Unova
/
Reshiram and Zekrom

But they also represent energy, two kinds of positive.
Hence there also exists a negative, an empty shell, the Wuji.
/
Kyurem



I assume this is the beginning of a second Tree of Legend.
We shall see.
