Underused Transformation
 

Do you have any transformation sequences that would be considered underused?

One that I could think of in particular is any transformation into a character from the 1980s, such as Lum (seen in Akuoreo's "Happy Easter" and Hipper-Reed's "TG That Obnoxious Locket") as well as this 80s-styled Rat Transformation by BringBackTheDead
