When Generation 5 was being rolled out, it was the most exciting time to be a Pokemon fan for me. At that time I was practically coming back to Pokemon so a fresh start was appreciated. Even better is that all the Pokemon were new, which means that every Pokemon reveal is very exciting.
I remembered when a trailer revealed certain Pokemon we won't know about later (the one with Excadrill, Haxorus, Cofagrigus and Galvantula comes to mind). That trailer also had Reuniclus, Gigalith and Gothitelle in a Triple Battle. It's also the time when I realised that fans prefer dual-typings over single-types, because some of the Pokemon with single-types were believed to be dual-typings. Example: Gigalith - Rock/Poison, Haxorus - Dragon/Bug, Cofagrigus - Ghost/Rock.
I would love another fresh start because of how great it is to encounter all-new Pokemon, but also because I hope the anime handles this premise better compared to BW (which I didn't mind, but I know a lot of people in the Pokemon forum that I frequent more often didn't like).
Thank you for reading.
