[Collectible of the day] Its all started from the device at the centre, the Digital Monster is a virtual pet released in 1997 by Bandai. This pet was much more masculine counterpart to the Tamagotchi that cater for fans of both gender. It was similar to earlier virtual pets with the distinctions of being a fighting pet that could connect with others.
When the first series of Digimon Adventure (Digimon) started, Bandai released a new design of Digital Monster device known as Digivice. The gameplay is a bit different from it's predecessor where you can select any of the 7 characters from the series. There's a clip for you to attach onto your belt or bags or even just put them into your pocket and "walk" with them. When there encounter another monster, it will beep and let you now so you can help your digimon to fight against it. You can still play it by shaking the digivice to let your digimon "walk" and clear the game. There's a hidden 8th character that you need to get which is Tailmon or Gatomon (US) after you collected all 7 digimon. As the game progressed, you can evolve the digimon from child level to Mega level to fight those monster and Boss level.
Due to the successful of the series and toyline, the series continue further with its second season until the latest 7th series, Digimon Universe: Appli Monsters. With all different TV series, also comes with different design and gameplay of the digivice. I skipped Season 4 digivice which is Digimon Frontier as it doesn't interest me much however for Digimon Xros Wars (6th Season) the digivice is pretty expensive due to the gameplay is coloured and different from others (Japan version), but for US released, it's actually black and white. I also manage to get the 15th Anniversary Digivice which is in the last picture, commemorating the 15th years of Digimon and the release of new Digimon Adventure Tri OVA. It's an upgraded version of the 1999 digivice.
