No starter pokemon will be on this list as all starters will eventually get a mega.
5. Xatu: The only reason xatu is used is because his decent stats of a BST-470 and his great ability magic bounce.
After mega evolution xatu should keep this ability and get a fairly large boost to defenses and HP with smaller boost to his sped and special attack. This will help xatu take a hit, prevent status and other no-attacking moves and he will be able to fire some good damage at the opponent.

4: Octillery: This pokemon is known for his great move pool and mixed attack stats. However his defenses are very low along with his bad speed and HP and a over all BST of 480. After mega evolution Octillery should get a large boost to special attack and a smaller boost to HP, defenses and attack. His ability should become sheer force as most of his moves have a secondary effect and will benifit from the boost.
3. Crobat: Crobat has bad special attack which is okay, his defenses are meh, Hp....meh, attack....how did he become so used! And speed...:D. Even though he may be decent he needs more power. I don't like him usage wise. After mega evolution crobat should revive a large attack boost and speed boost with a small HP and special attack boost. His ability should be defiant to prevent things with intimidate from wanting to come in.
2. Girafarig : Girafarig's stats are pretty bad. He has the special attack and speed he needs to get some rare klls but not much else. After mega evolution he should get a large boost to speed and special attack with a smaller boost to attack and all his defenses and HP. This will give girafarig the needed over all stat boost to help him succeed. His ability should be simple. This may seem like a stupid ability but it will help him set up fast with calm mind.
1. Ledian: Ledian is the best is it not? NO? Its not? Oh...well screw you ledian. He should get a mega for sure come on game freak. After mega evolution he should gain a attack boost taking him to at least base 100. He should also receive a boost to his HP and sp:def. He should get the ability huge power or pure power. This will let ledian do work and be a scary uu/ou threat. Come on should that be ru :I.
