It's a Toy Swap.

Sadly it happens all too often and as mentioned, is when someone buys a figure and returns it with anything from parts swapped out to an entirely different figure, and it happens all across the board.

It's common enough that there's an entry on the Transformers Wiki, Toy swapping - Transformers Wiki

Poe Ghostal has a spotlight on it, Toy Aisle Trolls, and in fact has an entry where someone swapped out a Mumm-Ra for a 200X Skeletor figure. Toy Aisle Trolls > Bumm-Ra : Poe Ghostal's Points of Articulation
