OK, voila la question!
I just bought (nary 6 hours ago) the Ultimate Brick, which contains the character White Rhino. Now, this character presumably has the seal of approval of our esteemed Mr. Long (May Peace Be With Him). The character appears to have multiple forms (human + rhinoid), yet to have neither Multiform not OIHID nor any relevant Disad. What's going on? Am I (as is very likely) missing something? Can one have multiple forms in some way without using these methods?
Thanks, I'm scratching my head here.
