Beginning January 1st 2020 Spin Master launched their new 4 inch Batman the Masked Crusader action figure line. Each figure has approximately 11 points of articulation. This guide was lasted update on August 12 2020.
The King Shark Mega Gear is part of the deluxe King Shark set from the new Batman Caped Crusader line made by Spin Master in 2020. While not technically a droid and more an exo-suit I plan on using it exclusively as a predator drone type robot in my collection.
Currently in-store at Target or Wal-Mart seem to be the best places to find this set.
