I imagine Mega Torterra to be bigger and have taller "mountains" and a taller tree. Maybe it's Ground type will be exchanged for rock. MegaInfernape could have better defenses and have it's arms and hands covered in flames. Also a more red color scheme.
MegaEmboar I see as having much higher defenses (they're some of the lowest if not the lowest out or all final evolve fire starters) so it'll be able to survive for several turns and get to attack, or maybe higher speed...
Yeah I'm hoping that if Unova's starters get Megas they might try and patch up the stats they were lacking in, like having Emboar get usable defenses since his low defenses make him easy kill. Or even buff up Serperior's Attack and Special Attack if it gets a Mega. Given they showed all the final evo starters on that image that showed a list of Pokemon that could have Mega Evolutions, despite some of the confirmed ones missing I wouldn't be surprised if they ended up using more Pokemon from that list.
I feel the new Pokémon in this issue like in the last issue will be overshadowed by the Megas and new type chart.
Yeah same too. It was like how Skiddo, Dedenne and Bunnelby were overshadowed by the announcement of Mega Evolutions itself. But still hoping the type chart turns out good.
