Mega Escavalier
Escavalier is, similar to other of my speculated pokemon, another well-forgotten pokemon. I think a mega could actually be good for Escavalier. No, I wouldn't put it at my top choice for a mega, but it isn't totally outrageous. Generation V needs new megas anyways.
What I can see happening for mega Escavalier is it becoming more bulkish, as well as upgrading the looks of its lances. I can also see more detail added to the bottom part of its helmet. However the most important thing Escavalier needs is a better way to move. Whether it is new legs (although that would look awkward, wings, or whatever, it needs a better way than just floating for no apparent reason. With all these changes, I can see massive increases in attack and defense, with a minor increase in special defense, and an even more minor increase in speed. As for its ability, we could make a new one, but there are a ton of abilities that could fit Mega Escavalier. It could keep Shell Armor, or it could have bulletproof, analytic, defiant, or adaptability. However, I think the best fit would be Anger Point.
I do have a second suggestion for Escavalier. Make it much more bulky and much slower. When I say make everything bulky I mean everything. Its lance, its armor, its body, and its helmet, all should be bulkier. If this were to happen it would get increases in all of its stats except special attack and speed.I think it should get Analytic, Anger Point, or just keep Shell Armor.
