A character created by the Japanese game developer Team ASOBI, first appearing in the 2016 title "Playroom VR" before making his debut in "Astro Bot Rescue Mission" in 2018.
As of 2023, he is used as the de-facto mascot for PlayStation and especially the PS5 and PSVR systems, to which he is native to, appearing in PSVR promotional material and even on Sony Japan's "CurioStep" education initiative. You can also find him on the PlayStation 404 page in every country (sans Japan).
His most recent game, "Astro's Playroom" is dedicated towards the history of PlayStation, with references to past games, hardware and even ideation of the console scattered in every nook and cranny of the platformer, giving most of its players glowing impressions. He is due for a new game soon, although no news has been confirmed as of now.
Also, both his appearance and attitude are extremely saccharine. Just look at him!
"Astro Bot just said hello to you! Now, isn't that adorable?"
