My concept for a Legends ZA mega:
MEGA DITTO!
The idea is that mega evolution caused it to rapidly multiply, so now it’s a big pile of dittos. It would have a new ability called “Shapeshifting Savant”, which works like imposter (auto-transform when activated) but would give a +20 bst increase to ATK, DEF, SATK, SDEF, and SPD (adding up to the +100 BST boost that all megas have). This essentially lets u steal ur opponents Mon but stronger, bulkier, and faster. It would be so annoying I love it
