Generation VI comes with a new way of evolving known as Mega Evolution, which grants some Pokémon an extra stage of evolution. A special stone and item is required for this purpose. Several Pokémon from each generation can have this as evolution.
Pokémon games followed 2D movement with 4 directions up to Generation V. In generation VI, this feature is expanded to 8 directions of up, down, left, right, upper left, upper right, lower left, and lower right.
Since the first generation, there have been third versions and as of Generation V, a sequel. However, unlike them, this generation doesn't feature a third version or sequel.
All Pokémon had their original cries updated as of this generation.
The word filter also returns in this generation, however the word filter in this generation works the same as that on the Global Trading System in Generation V: if the word is contained, it is censored entirely, making it less easier to evade. There are exceptions to this however, such as the censor on "kill": the word "skill" does not get blocked by the censor. There are more words added to this filter, and the list of censored words depends on whether one has the version updates or not installed on the 3DS console. This filter also detects using the space character between letters in attempt to evade the filter. Some words however have other words that are contained within the same offending category that are not censored as well, and if trying to enter any of the words on the banlist, the game will tell "You can't enter that word". The banlist is mostly based on the Nintendo 3DS censors.
There is no Pokemon Z, this might be because Zygarde only appears when Kalos is in dissaray.
