So I started thinking about how Mew could possibly learn every TM, HM, and Move Tutor move; and one thing led to another.
I’m sorry (I’m not sorry).
looks like the symbiont thing from that one anime took over mew….
Apparently two of them actually since its both his head and tail.
actually this makes a lot of sense considering mew is the only one other than ditto that can learn transform and it’s been shown to use transform in the movies.
