If the show is going to keep on expanding non-Green Arrow vigilantes on Arrow, I’m glad that Mr. Terrific has the background to make sense as a new fighting member of Team Arrow.
We can’t say at this point just how closely the mask and costume of Arrow’s Mr. Terrific will match those of DC’s Mr. Terrific.
Curtis could have developed Ray’s designs further to craft his unique supersuit for his role as Mr. Terrific.
The Spheres were most notable for malfunctioning and exploding, but it’s entirely possible that Curtis spent the summer perfecting them.
