About the guncannon tag
guncannon is a character tag that NovelAI Diffusion can use. On Danbooru it has 255 posts, and its best-rated still image scores 92. The samples above put the tag at the front of a fixed base prompt with seed 1234, so the differences between tags come from the tag alone.

Unit Designation: RX-77 Guncannon (the particular subtype that appeared in the show is RX-77-2)
In the compilation movie trilogy, after the Guntank was decommissioned at Jaburo, a second Guncannon is introduced. To differentiate it from the original Guncannon, both Guncannons receive numbered codenames, marked on the left chest, left shin, and right foot (those being C-108 and C-109).
Its shoulder cannons are sometimes parodied by other characters with similar equipment, such as Blastoise from Pokemon, Yasaka Kanako from Touhou, and Shigure from Kantai Collection.
It was designed by Yasuhiko Yoshikazu.
