Time for another mega a Mega thread /vp/, There aren't really any rules, just pick a Pokemon you like and make a Mega form for it. Picture can be included or not included, up to you. If you want give it abilities as well.

Normal Mode: Don't optimize it
Hard Mode: Don't make it broken
Dante Must Die Mode: Don't pick a favorite

I'm a casual faggot so I just disregarded everything.

Mega Starmie
Ability: Protean
60 > 60
75 > 75
85 > 105
100 > 130
85 > 105
115 > 145

I would imagine Mega Starmie growing slightly larger while its purple would deepen in color. The eye would shine bright as Gradius like options start circling around it. Protean would make sense to me due to the fact that starfishes can camouflage themselves in real life. It also gets reflect type anyway so I don't see it as big of a stretch. If I was going for maximum broken I'd allow it to learn Shadow Ball or Dark Pulse to round out its possible sets.
