Ark
Back in the 1970's there was a set of Bullmark toy makers that spun of the company Akron or Ark (U.S.). This company concentrated on some whimsical designs based on Ultraman and King Kong of all things. Ark robots have interchangeable parts, are made of heavy diecast, and tend to shoot off more missiles than anyone had or has done since. Ark toys are fun and dangerous.
